Pacific typhoon seasons 2022,2023,2024,2025,2026

The2024 Pacific typhoon season was the fifth-latest startingPacific typhoon season on record. It was average in terms of activity, and ended a four year streak of below average seasons that started in2020. It was also the deadliest season since2013, and became the fourth-costliest Pacific typhoon season on record, mostly due toTyphoon Yagi. This season saw an unusually active November, with the month seeing four simultaneously active typhoons. The season ran throughout 2024, though most tropical cyclones typicallydevelop between May and November. The season's first named storm,Ewiniar, developed on May 25, and eventually intensified into the first typhoon of the season, while the last named storm, Pabuk, dissipated on December 25. This season was an event in the annual cycle oftropical cyclone formation in the westernPacific Ocean, and it featured the most retired names in a single season—nine.

The scope of this article is limited to the Pacific Ocean to the north of theequator between100°E and180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones which can often result in a cyclone having two names. TheJapan Meteorological Agency (JMA)^{[nb 2]} will name atropical cyclone if it has 10-minutesustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin. ThePhilippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in thePhilippine Area of Responsibility (PAR), located between 135°E and 115°E and between 5°N–25°N, regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States'Joint Typhoon Warning Center (JTWC)^{[nb 3][nb 1]} are given a number with a "W" suffix; W meaning west, a reference to the western Pacific region.

During the year, several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium ofUniversity College London,PAGASA, Vietnam'sNational Center for Hydro-Meteorological Forecasting and Taiwan'sCentral Weather Administration.

Tropical Storm Risk (TSR) released their first forecast on May 7, predicting below average activity with 25 named storms, 15 typhoons and 7 intense typhoons. This was primarily due to the dominantEl Niño event at the time, which was expected to transition into a weak or moderateLa Niña by mid-2024.^[3] TSR released their early July forecast on July 5, where they slightly decreased the amount of storms and typhoons, mentioning the same factors as their previous forecast.^[4] On August 7, TSR released their final forecast for the season, retaining the same number of storms. However, they further decreased the predictedACE index, due to a slow start of the season and decreased tropical activity as of early August.^[5] Moreover, with thePacific Decadal Oscillation being in a negative phase since the beginning of 2020, they also mentioned how this season could become the lowest five-year activity since 1965.^[5]

The season began on May 23, when a tropical storm namedEwiniar formed southeast ofPalau, marking it as the fifth-latest start of a Pacific typhoon season since reliable records began. It also made Ewiniar the fourth-latest time and ended a 157-day period (December 18, 2023 – May 24, 2024) during which no named storm was active in the basin.^[8] Ewiniar tracked toward the Philippines, where it was namedAghon by PAGASA, the replacement name forAmbo. Ewiniar made nine landfalls inHomonhon Island;Giporlos, Eastern Samar;Basiao Island; Cagduyong Island;Batuan, Masbate;Masbate City;Torrijos, Marinduque;Lucena, Quezon andPatnanungan. It began to move over the warm tropical waters ofLamon Bay, where both the JTWC and the JMA upgraded Ewiniar into a minimal typhoon. Ewiniar began itsextratropical transition while it was 719 km (447 mi) east-northeast ofKadena Air Base inOkinawa, Japan. On June 6, another extratropical cyclone^[which?] would absorb the remnants of Ewiniar, just off the coast ofAlaska. On May 30, another tropical depression formed southeast ofHaikou, China. The next day, at 03:00UTC, JTWC designated the disturbance asTropical Depression 02W. A few hours later, JMA assigned the nameMaliksi to 02W as it was designated as a tropical storm. Shortly thereafter, on May 31, Maliksi made landfall inYangjiang, Guangdong. The JMA and JTWC discontinued warnings as Maliksi moved inland and dissipated on June 2. No storms formed in June for the first time since2010.

After many weeks of inactivity, on July 13, a tropical depression formed east of Vietnam, designated as03W. Shortly after, it tracked into Vietnam, dissipating soon after. On July 19, two tropical disturbances were recognized by the JTWC: one southeast ofManila and another east ofPalau. Soon after, both disturbances developed into a depression, being named by PAGASA. The first one, west ofBatangas, was namedButchoy while the second, east ofVirac, was namedCarina. Later that day, the JTWC followed suit, designating both as tropical depressions, with Butchoy being04W and Carina as05W. The next day, the more eastern disturbance, Carina, was namedGaemi by the JMA. On July 21, Butchoy also intensified into a tropical storm, receiving the namePrapiroon from the JMA. Prapiroon moved through the South China Sea as a mild tropical storm before making landfall overWanning, Hainan. Prapiroon moved throughGulf of Tonkin, where it further intensified into a severe tropical storm. Early on July 23, Prapiroon made its second and final landfall inQuảng Ninh, Vietnam.

Situated in a favorable environment in thePhilippine Sea, Gaemi continued to strengthen and became the second typhoon of this season. Gaemirapidly intensified into a very strong typhoon, with 10-minute sustained winds of 165 km/h (105 mph). Gaemi stalled and executed a counterclockwise loop near the coast, slightly weakening before making landfall over the northeastern coast of Taiwan. Weakened by the landfalls, the storm accelerated across the island and emerged into theTaiwan Strait, six hours after landfall. The next day, Gaemi made its final landfall atXiuyu, Putian inFujian Province as a weakening tropical storm. Moving inland, the storm rapidly weakened until it dissipated on July 27.

Even though Gaemi never made landfall in thePhilippines, the storm's moisture would enhance the southwest monsoon. Heavy rainfalls were felt overLuzon and some parts of theVisayas, leaving the regions flooded. Overall, Gaemi caused 152 fatalities and US$4.57 billion worth of damages throughout its track.

On August 3, a low-pressure area developed east ofKadena Air Base. At 00:00 UTC, JMA recognize the disturbance as a depression. However, it was downgraded to a remnant low on August 7. The convection later meandered south ofRyukyu Islands for a few days before JMA reclassified it again as a depression on August 11. JMA issued a gale warning the next day, citing that it would intensify in the following days. JTWC later followed suit and upgraded it intoTropical Depression 08W. On August 13, the depression became a tropical storm, receiving the nameAmpil from the JMA. Ampil gradually intensified in the Pacific Ocean, becoming a severe tropical storm. JMA upgraded Ampil into a typhoon two days later, and the JTWC classified it as a Category 2-equivalent typhoon. The next day, it strengthened into a Category 4-equivalent typhoon. The typhoon passed just south ofGreater Tokyo Area before weakening and transitioning to an extratropical cyclone.

On August 5, a low-pressure area formed inBonin Islands. The disturbance was in an environment with low to moderate wind shear and warm SSTs. The JTWC later classified the disturbance as a depression the next day, giving it the designation06W. Early on August 8, JMA upgraded the depression into a storm, naming itMaria. The storm further strengthened into a severe tropical storm on the same day. At the same time, JTWC reported that Maria had rapidly intensified into a typhoon due to strong equatorward and poleward outflow. However, on August 9, Maria weakened into a tropical storm as it moved northeastward. On August 10, another low-pressure area formed just southeast of Maria. The JTWC would classify the disturbance as a subtropical depression in their next bulletin. Despite being in a marginal environment and high wind shear, JMA upgraded into a tropical storm, giving it the nameSon-Tinh. The next day, JTWC reported that Son-Tinh became tropical, designating it as07W. Son-Tinh weakened back into a tropical depression before dissipating on August 14.

On the morning of August 12, Maria made landfall inIwate Prefecture as a tropical storm, bringing strong winds and heavy rains in northern Japan. After moving inland, Maria weakened into a tropical depression. The storm entered theSea of Japan, further weakening on the next day. The JTWC issued its final warning after Maria was last noted west-northwest ofMisawa. JMA continued to track the depression before they issued their final warning at 04:15 UTC.

Activity increased when an area of convection was formed on August 12 near the southwest of Son-Tinh. JMA would immediately recognize the disturbance as a tropical depression. The next day, JTWC went on classifying it as a tropical depression, designating it09W. Similar to Ampil, on August 13, 09W intensified into a tropical storm, receiving the nameWukong from the JMA. Wukong was short-lived due to its poorly organized cloud tops. JTWC made its final warning for Wukong as it moved through cooler waters and dissipated on August 15.

On August 17, JMA recognized a tropical depression that formed east of Taiwan. The next day, PAGASA declared the system a tropical depression, naming itDindo. The depression was namedJongdari by the JMA three hours later upon intensification to a tropical storm. JTWC later followed suit and upgraded Jongdari into a tropical storm, with the designation of10W. However, it did not last long and weakened into a tropical depression while nearing theKorean Peninsula. On August 21, JMA and JTWC reported that Jongdari had dissipated as its low-level circulation center faded when it moved over land. After Jongdari, a low-pressure area formed in theNorthern Mariana Islands on the same day. The system intensified into a tropical storm the next day, with the JMA naming itShanshan. JTWC then gave Shanshan the designation11W.

Shanshan later strengthened into a Category 1-equivalent typhoon. It remained at that intensity as it battled through wind shear. As it went near theAmami Islands, it strengthened into a Category 4-equivalent typhoon. The approach of the typhoon caused the issuance of aspecial warning system in Kagoshima Prefecture, the first time in the area sinceTyphoon Nanmadol in 2022. Around 08:00 JST on August 29, Shanshan made landfall nearSatsumasendai, making it the third tropical cyclone impacting mainland Japan this season. Rapid erosion later ensued as it moved eastward while inland. Shanshan heads overSeto Inland Sea before it makes another landfall inShikoku on the next day. Shanshan's convection began to be disorganized, causing it to weaken into a remnant low. However, it strengthened back into a tropical depression as it moved east-southeastward through open waters. JMA continued to track Shanshan until it dissipated on September 1.

On August 30, a tropical disturbance formed nearPalau. On the same day, JMA started to issue advisories for the system as a depression. As it entered thePhilippine Area of Responsibility (PAR), the PAGASA named itEnteng on September 1. JTWC followed suit, and Enteng was classified as a tropical depression, with the designation12W. At 21:00 JST (13:00 UTC), JMA classified Enteng as a tropical storm, naming the systemYagi. The storm made its first landfall inCasiguran inAurora Province at 14:00PHT on September 2. The mountainous terrain of theCordillera Central made Yagi weaken as it moved inland. It exited the PAR early on September 4 as it continues to intensify in theSouth China Sea.

Entering the South China Sea, Yagi later strengthened into a typhoon due to its highly favorable environmental conditions. The following day, it rapidly intensified, developing a distinct eye and briefly reaching Category 5-equivalent super typhoon status at 00:00 UTC on September 5 as it approachedHainan. The whole cloud system of Yagi covered the entire South China Sea. Yagi slightly weakened before it made its second landfall overWenchang City in Hainan. The storm then moved over Haikou, and continued to make another landfall inXuwen County,Guangdong. Afterward, Yagi entered the open waters of the Gulf of Tonkin.

Yagi became one of only the four Category 5 typhoons recorded in the South China Sea, alongsidePamela in1954,Rammasun in2014, andRai in2021. It also marked the most powerful typhoon to strike Hainan in autumn since Typhoon Rammasun. On September 7, Yagi underwent a period of reorganization and regained Category 4 status before making a historic landfall betweenHaiphong andQuảng Ninh in Vietnam. Upon landfall, Yagi became the strongest storm in history to impactNorthern Vietnam. The typhoon then rapidly weakened as it moved inland, becoming a tropical depression on September 8. The JMA continued monitoring the system before reporting that Yagi dissipated at 18:00 UTC on the next day. Even after dissipation, it still wreaked havoc, bringing heavy floods toMyanmar,Laos, andThailand.

While Yagi was still on its way to making landfall in the Philippines, JTWC announced another formation of a tropical disturbance in the open Pacific Ocean on September 2. JMA also started issuing advisories, and it was recognized as a tropical depression in the same location. Two days later, as JTWC also upgraded it into a tropical depression, it received its designation,13W. The day after, JMA reported that 13W developed into a tropical storm, giving it the nameLeepi as the twelfth named storm of this season. Leepi then accelerated northeastwards before it became an extratropical cyclone on September 6.

On September 9, a tropical depression formed over theMicronesian Islands. The following day, the JTWC designated it as14W. As it moved over Guam, 14W intensified into a tropical storm and was namedBebinca by the JMA. Despite encountering dry air, Bebinca still strengthened as it began its northwestward movement. At 18:00 PHT on September 13, Bebinca entered the Philippine Area of Responsibility and was namedFerdie by PAGASA. Bebinca later strengthened into a minimal typhoon on the next day. On September 16, Bebinca made landfall inLingang New City inShanghai as a weakening Category 1 typhoon. Bebinca became the strongest typhoon to hit Shanghai sinceTyphoon Gloria in1949.

As Bebinca moved toward eastern China, two tropical depressions formed in the Pacific on September 15—one near Guam and another within the Philippine Area of Responsibility (PAR). The JTWC designated the depression near Guam as15W. It soon intensified into a tropical storm and was namedPulasan by the JMA. The other tropical depression, being in the PAR, was given the nameGener by the PAGASA. At 02:00 PHT on September 16, Gener made landfall overPalanan, Isabela. The storm continued to move westward over Northern Luzon, maintaining its strength as a tropical depression. Meanwhile, Pulasan briefly entered the PAR at 18:30 PHT (10:30 UTC) and was given the nameHelen. On September 18, two disturbances in the South China Sea, Invests 98W and 99W were expected to merge and strengthen as 98W, closer to Vietnam. Shortly after, Gener was upgraded into a tropical depression by the JTWC, getting the designation16W. On September 19, 16W was upgraded to a tropical storm and namedSoulik by the JMA. Soulik made landfall overVĩnh Linh District,Quảng Trị Province in Vietnam. Meanwhile, Pulasan also made landfall overZhoushan,China, similar to where Bebinca had made landfall three days earlier. After that, it made a second landfall over Shanghai, marking the first time since reliable meteorological records exist that two typhoons make landfall over Shanghai with only two days in between.

On September 20, a low-pressure area formed over Northern Luzon. The JTWC later designated the disturbance asInvest 90W upon its formation. As it was inside the PAR, PAGASA initiated advisories and named the systemIgme. The JTWC soon upgraded it into a tropical depression, designating it as17W. Igme later curved southwestwards, passing closely toTaiwan. The storm later dissipated on September 22 after topographical interaction, and high vertical wind shear had significantly weakened the system.

Two days later, on September 24, a tropical depression formed in the Pacific south of Japan. That day, JTWC designated the system as18W. The following day, the JMA upgraded the depression into a tropical storm, assigning it the nameCimaron. The storm moved southwestwards, maintaining its intensity. As it moved westwards, Cimaron weakened into a tropical depression as an unfavorable environment hindered any intensification. Cimaron later dissipated on September 27. Shortly later the same day, another low-pressure area formed near theNorthern Mariana Islands. Despite being in a marginal environment, the disturbance managed to organize and was designated as19W by the JTWC. On September 27, the JMA upgraded 19W into a tropical storm, naming itJebi. At first, Jebi struggled to organize due to the presence of moderate low-level wind shear, causing Jebi to weaken into a tropical depression. However, Jebi redeveloped back into a tropical storm after. The storm continued to organize until it further intensified into a Category 1 typhoon by the JTWC, while according to the JMA, it only reached the intensity of a severe tropical storm. Jebi later transitioned to an extratropical cyclone, and both agencies issued their final warning on October 2.

Shortly after Cimaron weakened into a tropical depression, a low-pressure area formed in thePhilippine Sea near extreme northern Luzon on September 26. The PAGASA started issuing bulletins regarding the disturbance and was namedJulian as it strengthened into a tropical depression. The following day, the JTWC designated Julian as20W, also upgrading it into a tropical depression. On September 28, the JMA upgraded 20W into a tropical storm, naming itKrathon, a replacement name forMangkhut. It then intensified into a Category 1 typhoon, heading towardsSabtang, Batanes. Shortly after, the typhoon began itsrapid intensification and in two days, the system reached its peak intensity equivalent to a Category 4 super typhoon. On October 3, Krathon made landfall overSiaogang District inKaohsiung, Taiwan. The typhoon became the first storm to make landfall in Taiwan's densely populated western plains sinceTyphoon Thelma in1977. The storm weakened while moving inland, marking the first time this had happened in Taiwan sinceTropical Storm Trami in 2001. The JMA continued to track the system to the South China Sea before it dissipated on October 4.

On October 5, a tropical depression formed near Guam. The following day, the JTWC designated it as21W. Despite moving through warm waters, high wind shear hindered any further development, causing it to weaken back into a disturbance. On October 8, the JTWC issued its final warning, with dissipation expected in the next 12 hours. The next day, 21W intensified into a tropical storm, receiving the nameBarijat from the JMA. Later in the day, JTWC reissued advisories on Barijat and strengthened into a tropical storm. However, both agencies later made their final warning for the last time as the storm dissipated on October 11.

On October 19, a tropical depression formed nearbyYap. The next day, it was assigned as22W by the JTWC. Then, it moved into the PAR and was namedKristine by the PAGASA. Soon after, the JMA upgraded it to a tropical storm and was given the nameTrami. Many parts of the Philippines were issued wind storm signals prior to its approach to the country. On October 23, Trami strengthened into a severe tropical storm, prompting the upgrade toTropical Cyclone Wind Signal No. 3 in parts of northern and central Luzon. At 04:30 UTC on October 24, Trami made landfall over the province ofDivilacan, Isabela. The following day, Trami emerged above the coastal waters of southernIlocos Sur, leaving the remnants of a circulation center over northern Luzon. This caused torrential rains and gusty winds throughout the day in many areas of the country.

Trami continued crossing the South China Sea while maintaining severe tropical storm strength. As it approached the coast of Vietnam, the storm encountered strong easterly vertical wind shear. It made landfall inDa Nang at 10:00ICT on October 27. Trami then drifted southwestward due to weak steering flow and later made a U-turn over Vietnam's coastal regions. The storm eventually weakened into a low-pressure area, with agencies issuing their final warning on October 29.

As Trami crossed the Cordillera Central, another tropical disturbance developed southeast of Guam on October 24. The JMA began monitoring the system as a tropical depression and issued a gale warning. On the following day, the JMA upgraded the disturbance to a tropical storm, naming itKong-rey. At the same time, another disturbance designated asInvest 99W formed to the north. As a result, the JTWC cancelled warnings for the southern system (Invest 98W) and reclassified Kong-rey under 99W. The JTWC later designated the system asTropical Depression 23W. The storm then entered the PAR, where it received the local nameLeon. On October 29, Kong-rey started undergoing rapid intensification and became a Category 4-equivalent super typhoon the following day. With that, Kong-rey achieved a peak intensify of 1-minutesustained winds of 240 km/h (150 mph) and a minimum centralpressure of 925 hPa (27.32 inHg).

Shortly after reaching its peak intensity, Kong-rey started to slightly weaken while undergoing aneyewall replacement cycle as it tracked northwestward. The typhoon later made a historic landfall overChenggong, Taitung in Taiwan, marking the first major typhoon to strike the island after mid-October and the most powerful sinceTyphoon Herb in 1996. Kong-rey then emerged through theTaiwan Strait with a weakened convective structure around the center. It continued to weaken and transitioned to an extratropical cyclone overSasebo, Japan, prompting both agencies to issue their final advisories on November 1.

Shortly after Kong-rey transitioned to a post-tropical cyclone, an area of low pressure formed near Palau on November 1. Initially, the JTWC ceased issuing advisories due to unfavorable environmental conditions. However, as the system began to show increased organization two days later, the JTWC resumed advisories. At 14:00 UTC on November 3, both the JTWC and the JMA upgraded the system to a tropical depression, with the former assigning it the designation24W. Later that day, at 18:00 UTC, it intensified into a tropical storm and was namedYinxing by the JMA, the replacement name forYutu. Upon entering the PAR, Yinxing received the local nameMarce from the PAGASA. It continued to intensify over the Philippine Sea, prompting both agencies to classify it as a typhoon the following day. It then reached its peak intensity of a Category 4-equivalent typhoon, with 1-minute sustained winds of 230 km/h (145 mph) and a minimum central pressure of 940 hPa (27.76 inHg). At around 15:40 PHT (07:40 UTC) on November 7, Yinxing made landfall overSanta Ana, Cagayan. After traversing the Babuyan Channel in theLuzon Strait, it made its second landfall overSanchez Mira, Cagayan. The storm slightly weakened into a Category 2-equivalent typhoon after making landfall, but later reintensified as a Category 3-equivalent typhoon on November 9 as it moved into theSouth China Sea. On November 10, Yinxing was steadily weakening, with itsCDO becoming more asymmetric as it encountered cooler sea surface temperatures and increasing vertical wind shear. The storm moved southwestward between two mid-level subtropical ridges, and its convective structure became increasingly asymmetric. Strong southwesterly shear disrupted the central dense overcast and exposed the low-level circulation, prompting the JMA to downgrade the system to a tropical storm at 00:00 UTC. Despite maintaining a compact circulation with an eye-like feature near the southern coast of Vietnam, convection remained disorganized. At 07:00 UTC on November 12, Yinxing made landfall just north ofQuy Nhơn. The JTWC issued its final warning shortly after landfall, with the JMA continuing to monitor the system until it dissipated inland at 18:00 UTC the same day.

On November 8, a tropical disturbance developed east of Southern Luzon and began moving westward in a favorable environment. At 08:00 PHT (00:00 UTC) on the following day, the system entered the PAR and was assigned the nameNika by the PAGASA. Shortly afterward, another area of low pressure formed near theMarshall Islands and was designated asInvest 93W. With favorable conditions and low vertical wind shear, the JTWC issued aTropical Cyclone Formation Alert (TCFA) for the system. Later that day, both 93W and Nika were upgraded to tropical depressions, with the systems designated as25W and26W respectively.

Later that day, both systems intensified into tropical storms and were namedMan-yi andToraji by the JMA. On November 10, Toraji continued to strengthen and was upgraded to a severe tropical storm by the JMA, while the JTWC classified it as a Category 1 typhoon as its outer bands became more organized. The JMA subsequently upgraded Toraji to typhoon status before it made landfall inDilasag, Aurora. The system then exited into the South China Sea nearMagsingal, Ilocos Sur, with satellite imagery showing a compact and tightly wrapped low-level circulation. As Toraji moved northwestward, its low-level circular convection weakened over the center, and the storm was downgraded to a tropical storm on November 11. Satellite imagery later showed a weakening of deep convection at its center, with low-level cloud banding visible around the center and along the southern edge of the circulation. This was attributed to strong southerly vertical wind shear as the system became embedded in the low-level northeasterly flow associated with a cold surge. As a result of convective decapitation that left the low-level circulation fully exposed, the JTWC issued its final advisory on November 14, downgrading the system to a tropical depression. The JMA continued monitoring the system until it was last noted at 06:00 UTC on November 15.

Meanwhile, on November 9, a tropical depression formed nearMicronesia. The following day, the JMA began issuing warnings on the system. On November 11, the JTWC upgraded it into a tropical depression, designating it as27W. By early morning of the next day, 27W intensified into a tropical storm, prompting the JMA to assign the nameUsagi. This marks the first time in reliable meteorological records that four active systems were active simultaneously in the basin during November.^[9] Around the same time, Usagi entered the PAR, receiving the local nameOfel from PAGASA. The storm continued to intensify and underwent a period of rapid intensification, reaching Category 4-equivalent super typhoon strength on November 14. At 13:30 PHT (05:30 UTC) of the same day, Usagi made landfall overBaggao, Cagayan. After landfall, Usagi began to weaken as its eye became obscured due to interaction with mountainous terrain. After crossing northern Luzon, it emerged into the Babuyan Channel, moving northwestward along the edge of a mid-level subtropical high. The system passed near theBabuyan Islands and northern Cagayan, prompting the JMA to downgrade it to a severe tropical storm. Satellite imagery showed a weakening low-level circulation with convection displaced northeast of a partially exposed center. As Usagi drifted southwest of Taiwan, it continued to weaken due to strong vertical wind shear, leading the JTWC to issue its final warning on November 16. The JMA monitored the system until it dissipated at 12:00 UTC on the same day.

Upon being named Usagi as 27W, the Western Pacific basin experienced a rare meteorological occurrence on November 12: two typhoons were active in the South China Sea simultaneously for the first time sinceAngela in 1992. It also marked the first time since records began in 1951 that four tropical cyclones were simultaneously active in November, and the first time in the basin since 1970.

Meanwhile, after maintaining tropical storm strength for five days, the JMA upgraded Man-yi to a severe tropical storm as it entered a more favorable environment. At 20:00 PHT (12:00 UTC) on November 14, the storm entered the PAR, where it was given the namePepito by the PAGASA. By early on November 16, Man-yi had rapidly intensified and peaked as a super typhoon, with estimated 1-minute maximum sustained winds of 260 km/h (160 mph) and a central pressure of 920 hPa (27.1 inHg). At 21:40 PHT (13:40 UTC), Man-yi made its first landfall overPanganiban, Catanduanes, bringing destructive winds and torrential rain. The following day, it made a second landfall inDipaculao, Aurora in Luzon at around 15:20 PHT (07:20 UTC).,^[10] with theSierra Madre mountain range disrupting its structure and causing the eye to collapse. Man-yi then accelerated northwestward into the South China Sea, weakening into a severe tropical storm as vertical wind shear increased. The JTWC issued its final warning on November 19 as Man-yi weakened into a tropical depression, while the JMA continued monitoring the system until it was last noted at 06:00 UTC on November 20.

After several weeks of inactivity, a low-pressure area developed southeast of Mindanao on December 17. The following day, the disturbance entered the PAR, where it was classified as a tropical depression and assigned the nameQuerubin by PAGASA, replacing the retired nameQuinta. Despite favorable environmental conditions, Querubin struggled to organize due to its proximity to land, which hindered development. The JTWC issued two TCFAs, citing a high probability of intensification. However, as Querubin crossed between the Visayas andMindanao, PAGASA issued its final advisory on December 18, declaring it a well-marked low-pressure area. The JTWC continued to monitor the system, though downgraded it to a low chance of development, before ceasing bulletins the following day.

The final tropical cyclone of 2024 developed on December 20 over northeast Malaysia and was designated as Invest98W. The system brought gusty winds acrossSarawak,Sabah, andBrunei throughout its formation. The next day, the JTWC issued a TCFA, citing high chances of development. However, the emergence of a nearby disturbance, designatedInvest 99W, led the JTWC to lower the development potential of 98W and shift focus to the new system. Despite remaining outside the PAR, the PAGASA named the disturbanceRomina, replacing the retired nameRolly due to its potential impact on theKalayaan Islands. This marked the first time that PAGASA has assigned a local name to a system outside the PAR since 1963. The JTWC later designated Romina as28W, and the JMA subsequently upgraded it to a tropical storm, assigning the international namePabuk. The storm tracked westward before turning toward Vietnam, weakening into a tropical depression as it encountered strong low-level northeasterly flow associated with a cold surge. The final advisory on Pabuk was issued at 18:00 UTC on December 25 as it degenerated into a well-marked low-pressure area.

Peak intensity	140 km/h (85 mph)(10-min); 970 hPa (mbar)

On May 21, theJoint Typhoon Warning Center (JTWC) began tracking an area ofatmospheric convection 441 km (274 mi) southeast ofPalau, noting that the system was moving northwestward towards an environment favorable fortropical cyclogenesis.^[11] By May 23, the disturbance became a tropical depression.^[12] The depression would later enter PAR, assigning the nameAghon, a replacement name forAmbo.^[13] At 18:00 UTC, the JTWC designated the depression as01W, based on surface observations fromGuiuan.^[14] Aghon made landfall overHomonhon Island and subsequentlyGiporlos,Eastern Samar in the early morning of May 25 (PHT).^[15] It made five more landfalls overBasiao and Cagduyong Islands ofCatbalogan;Batuan inTicao Island;Masbate City; andTorrijos, Marinduque.^[15] At 12:00 UTC, 01W intensified into a tropical storm while it was still inTayabas Bay, which prompted the JMA to name the storm asEwiniar.^[16] In the morning of May 26 (PHT), the storm made its eighth landfall overLucena, Quezon inLuzon island.^[15] Ewiniar later intensified into a typhoon overLamon Bay^[17] The storm made its final landfall overPatnanungan in thePolillo Islands.^[15] The typhoon left the PAR on May 29 and continued to weaken due tosubsidence around the mid-latitude.^[17][15] On May 30, Ewiniar transitioned into anextratropical cyclone south-southwest ofYokosuka, Japan.^[18] Then at 18:00 UTC on May 31, Ewiniar entered thebaroclinic zone and an area of high wind shear.^[17]

Typhoon Ewiniar resulted in ₱1.03 billion (US$20.88 million) in total damages in the Philippines, with ₱85.63 million (US$1.74 million) to agriculture and ₱942.55 million (US$19.14 million) to infrastructure, while also causing six deaths, injuring eight people, and impacting around 152,266 others. In Japan, heavy rainfall was observed in several regions, with a maximum of 52.5 mm (2.07 in) of rain being recorded inMiyake, Tokyo.^[19][20]

Duration	May 30 – June 2
Peak intensity	65 km/h (40 mph)(10-min); 998 hPa (mbar)

On May 29, the JTWC began tracking an area of convection located 406 km (252 mi) southeast ofHaikou,China. Being in an area of warm waters and low vertical shear and having southerly outflow, the system sustained a weak circulation, inhibited from development by another area of convection nearMainland China.^[21] It was recognized as a low-pressure area by theJapan Meteorological Agency (JMA) early the next day,^[22] before the agency upgraded it to a tropical depression at 06:00 UTC.^[23] Later that day, the JTWC issued aTropical Cyclone Formation Alert (TCFA) on the depression since it had rapidly developed.^[24] At 00:00 UTC the next day, the JTWC upgraded the system into a tropical depression, designating it as02W.^[25] Later, the JMA upgraded it into a tropical storm, and it was given the nameMaliksi.^[26] However, the JTWC reported that it did not intensify into a tropical storm as it was disorganized, with the circulation elongating.^[27][28] At 21:00 UTC on May 31, the JTWC discontinued warnings on the system as it made landfall inYangjiang, Guangdong.^[29] Soon after, the JMA last noted Maliksi as a depression on June 1 before weakening further into a low-pressure area the next day, as it tracked inland.^[30][31][32]

On May 30, theHong Kong Observatory issued aNo. 1 standby signal as the depression neared Hong Kong.^[33] The next day, it upgraded the warnings into a No. 3 Strong Wind signal.^[34] Although it was likely to not directly affectTaiwan, theCentral Weather Administration noted that Maliksi's remnants were likely to merge with a frontal system and bring heavy rains to Taiwan over the weekend.^[35] InMacau, the storm caused unstable weather, with theMeteorological and Geophysical Bureau issuing Typhoon Signal No. 3.^[36][37] In China, torrential rainfall occurred, peaking at 272.3 mm (10.72 in) somewhere in theLeizhou Peninsula. Additionally, heavy rain was recorded inFujian,Zhejiang andJiangxi.^[38]

Duration	July 13 – July 15
Peak intensity	55 km/h (35 mph)(10-min); 1000 hPa (mbar)

On July 13, the JTWC began tracking an area of convection 423 mi (682 km) east-southeast ofDa Nang,Vietnam. At the time, the disturbance was in a marginal environment for development, with high vertical wind shear offsetting good divergence aloft alongside warm sea surface temperatures.^[39] At 06:00 UTC of that day, the JMA designated the system as a tropical depression.^[40] The JTWC then issued a TCFA on the system the next day, noting its symmetrical center had improved as it moves northwest, though convection was disorganized.^[41] By 18:00 UTC the next day, the JTWC upgraded the system into a tropical depression, designating it03W.^[42] However, they issued their last warning on the depression early the next day as it moved overVietnam and rapidly weakened.^[43] Later that day, the JMA stopped tracking the depression as it dissipated.^[44]

Very strong typhoon (JMA)
Category 4 typhoon (SSHWS)
Duration	July 19 – July 29
Peak intensity	165 km/h (105 mph)(10-min); 935 hPa (mbar)

On July 17, the JMA reported that alow-pressure area had formed east ofPalau.^[44] Shortly after, both the JMA and the JTWC followed suit and upgraded the tropical depression,^[44] with the latter designating the system as05W.^[45] The PAGASA followed suit a few hours later, recognizing the system as a tropical depression and naming itCarina.^[46] Early the next day, the depression intensified into a tropical storm, and was given the nameGaemi by the JMA.^[47] Due to a weak steering environment between thesubtropical ridge to the northwest and east, the JTWC upgraded Gaemi to minimal typhoon around 21:00 UTC that day.^[48] On July 24, Gaemi later rapidly intensified and peaked at Category 4-equivalent intensity on theSaffir-Simpson scale at 21:00 UTC on 23 July, with 1-minute sustained winds of230 km/h (145 mph) by the JTWC, 10-minute sustained winds of165 km/h (105 mph) by the JMA, and a central pressure of 935 hPa (27.61 inHg).^[49][47] After stalling and executing a tight counter-clockwise loop near the coast,^[50] Gaemi slightly weakened into a below-equivalent typhoon status due to land interaction before it madelandfall on the northeastern coast ofTaiwan on July 24.^[51] Gaemi accelerated as it moved across the island and emerged into theTaiwan Strait just six hours after making landfall.^[52] Soon after,^[53] the JTWC ceased issuing advisories on the system as it made its final landfall atXiuyu, Putian inFujian Province.^[54] Once inland, the JMA downgraded Gaemi into a tropical depression on July 26^[47] and continued tracking the system until it dissipated at 18:00 UTC of July 29.^[32]

Thesouthwest monsoon, combined withTropical Storm Prapiroon, brought heavy rains to southern and northern Luzon, triggering widespread flash floods that resulted in at least 126 deaths and caused damage estimated at US$2.31 billion across several countries.^[55][56][57]

Severe tropical storm (JMA)
Tropical storm (SSHWS)
Duration	July 20 – July 25
Peak intensity	100 km/h (65 mph)(10-min); 985 hPa (mbar)

On July 15, the JTWC started to monitor a persistent area of convection roughly 623 km (385 mi) southeast ofManila,Philippines. At that time, the disturbance was in a favorable environment for development, with warm 29–30 °C (84–86 °F), sea surface temperatures, low wind shear and good equatorialoutflow.^[58] At 06:00 UTC the same day, the JMA designated the system as a low-pressure area.^[44] Shortly after, the JMA designated it as a tropical depression.^[44] The PAGASA declared the system a tropical depression a few hours later. Since the storm formed within thePhilippine Area of Responsibility, the agency named itButchoy.^[59] The JTWC began issuing advisories on the system, classifying it as04W.^[60] It intensified into a tropical storm and was namedPrapiroon by the JMA on July 21.^[61][62] The center of Prapiroon made landfall nearWanning, Hainan, with 1-minute sustained winds of95 km/h (60 mph) on July 22.^[63] After making landfall, the storm maintained its well-defined eye while moving across central Hainan.^[64] Prapiroon soon encountered high wind shear and a dry environment,^[65] and by 6:30 a.m. local time on July 23, it made its second landfall inQuảng Ninh, Vietnam.^[66][67] After the system moved inland, both the JMA and the JTWC ceased monitoring it on July 24.^[44][68]

Typhoon Gaemi and Prapiroon, along with its precursor, significantly impacted the southwest monsoon over the Philippines, leading to heavy rainfall that caused 23 deaths, 9 people missing, and US$32.9 million in damages across several countries.^[69][70][71]

Severe tropical storm (JMA)
Category 1 typhoon (SSHWS)
Duration	August 5 – August 14
Peak intensity	100 km/h (65 mph)(10-min); 980 hPa (mbar)

On August 5, the JMA stated that a tropical depression had formed.^[44] Later that day, the JTWC began tracking it, noting the depression was in an environment with low to moderate wind shear, warm sea surface temperatures, and good equatorward outflow aloft.^[72] At 09:00 UTC on August 6, the JTWC issued a TCFA on the disturbance, which was located 423 mi (682 km) north-northwest ofIwo Jima, along the eastern periphery of the monsoon gyre,^[73] prior to it being designated as06W.^[74] The development of acentral dense overcast and a ragged eye feature signified its intensification into a tropical storm,^[75] leading the JMA to name itMaria on August 7.^[76] Maria then turned northeastward,^[47] and intensified into a severe tropical storm on August 8 due to a favorable environment for development.^[47] Concurrently, the JTWC then reported that Maria had rapidly intensified into a minimal typhoon due to strong equatorward and poleward outflow.^[77] However, Maria's wind field became more asymmetric, with its associated convection shifting northward,^[78] causing Maria to weaken into a tropical storm on August 9.^[79] Around 00:00 UTC on August 12, the storm made landfallŌfunato,^[80] a city inIwate Prefecture,Japan with winds of85 km/h (50 mph) before traversing northernHonshu and emerging into theSea of Japan.^[81] The JMA continued to monitor the system until it was last noted at 18:00 UTC on August 14.^[44]

Record-breaking rainfall in Iwate Prefecture, with 19 inches (482.6 mm) inKuji and 12.6 inches (320.0 mm) inOtsuchi—nearly double the average for August—led to controlled releases from theTaki Dam in Kuji, necessitating the evacuation of 8,300 people and the issuance of the highest evacuation alert level, though no damage or injuries were reported in association with Maria.^[82]

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	August 10 – August 14
Peak intensity	75 km/h (45 mph)(10-min); 994 hPa (mbar)

On August 10, the JMA noted that a tropical depression had formed southeast of Severe Tropical Storm Maria.^[47] A few hours later, the JTWC began tracking the system, noting that it could transition into a tropical cyclone despite intense wind shear.^[83] Early the next day, they noted that the depression had transitioned into a subtropical cyclone.^[84] As a result, a few hours later, the JMA named itSon-Tinh.^[47] The next day, the JTWC noted that it had transitioned into a tropical storm, designating it07W.^[85] Soon after, the low-level circulation center became fully exposed with no deep convection existing near the center.^[86] On August 13, Son-Tinh turned northwest along the western edge of a subtropical ridge.^[87] Both the JMA and the JTWC stopped monitoring it as a tropical depression that day,^[47] though the JMA continued to track it until it was last noted the following day.^[44]

Very strong typhoon (JMA)
Category 3 typhoon (SSHWS)
Duration	August 11 – August 19
Peak intensity	155 km/h (100 mph)(10-min); 950 hPa (mbar)

On August 3, the JTWC began tracking an area of convection 976 km (606 mi) east ofKadena Air Base on August 3.^[88] At 18:00 UTC the same day, the JMA designated the system as a low-pressure area.^[44] However, the following day, the system was upgraded to a tropical depression.^[44] The depression weakened and was last noted by the JMA on August 7.^[44] The disturbance later meandered south of theRyukyu Islands for a few days before it was re-designated by the JMA as a tropical depression on August 11.^[44] A few hours later, they recognized the system as a tropical depression, designating it as08W.^[89] Soon after, the JMA noted that it had intensified into a tropical storm and named itAmpil.^[47] The JMA then reported that Ampil had intensified into a typhoon due to warm sea surface temperatures and low vertical wind shear on August 15.^[47] The JMA reported that Ampil reached its peak intensity at 12:00 UTC that day with 10-minute sustained winds of155 km/h (100 mph) and a central pressure of 950 hPa (28.05 inHg) before making its closest approach toJapan, and transitioned into an extratropical low on August 19.^[47]

Ampil brought strong winds and coastal waves to westernAlaska, whileTokyo experienced minimal damage according toNHK, althoughKanagawa Prefecture saw several injuries; the remnants of Ampil also contributed to anatmospheric river as its moist core flowed into a low-pressure system, ultimately being absorbed into the Pacificjet stream and anticipated to impactCalifornia.^[90]

Tropical depression (SSHWS)
Duration	August 11 – August 16
Peak intensity	65 km/h (40 mph)(10-min); 1002 hPa (mbar)

On 12 August, the JMA noted that a tropical depression formed southwest of Tropical Storm Son-Tinh.^[44] A few hours later, strong convection south of the system's low-level circulation center consolidated, which prompted the JTWC to issue a TCFA for the disturbance.^[91] Soon after, they recognized the system as a tropical depression, designating it as09W.^[92] Satellite imagery revealed that a central dense overcast obscured the center, leading to the depression strengthening into a tropical storm namedWukong by the JMA,^[93] although moderate vertical wind shear displaced the deep convection to the southeast.^[94][47] Wukong then shifted northwestward, following the eastern edge of a subtropical ridge, while also being affected by the shear and outflow fromTyphoon Ampil to the southwest.^[95] On August 15, both the JMA and the JTWC ceased monitoring the system, with the JMA reporting that Wukong had transitioned into an extratropical low due to moderate vertical wind shear and cooler sea surface temperatures.^[96][47]

Tropical storm (SSHWS)
Duration	August 18 – August 22
Peak intensity	75 km/h (45 mph)(10-min); 996 hPa (mbar)

On August 17, a low-pressure area east of Taiwan developed into a tropical depression.^[44] Soon after the development of a low-level circulation center and deep convection, the JTWC issued a TCFA for the disturbance.^[97] A few hours later, PAGASA declared the system a tropical depression and named itDindo,^[98] while the JMA reported it had intensified into a tropical storm and named itJongdari,^[47] and the following day, the JTWC recognized it and designated it as10W.^[99] Jongdari became devoid of convection as it was displaced from its exposed low-level circulation center and turned north-northeastward along the western edge of a subtropical ridge.^[100] Jongdari then weakened as it moved into theYellow Sea and made landfall over theKorean Demilitarized Zone on August 20 before emerging into the Sea of Japan.^[44][101] The JTWC assessed the cyclone as having dissipated and ceased issuing advisories on the system,^[102] while the JMA continued to monitor the system until it was last noted on August 21.^[44]

In some parts of the southern islands ofJeju, Jongdari accumulated 60–130 millimetres (2.4–5.1 in) of rain as it moved closer to the coast.^[103] One person was killed as a result of Jongdari, when a 60-year-old man drowned in a port located onHeuksando,Sinan County. He was a 43-ton fishing boat crew member that docked in the port to seek refuge from the storm.^[104]

The remnants of Jongdari caused heavy rain and triggered flooding inLiaoning,China. 27 people were dead or missing, total damage reached 15.47 billion yuan (US$2.15 billion).^[105]

Very strong typhoon (JMA)
Category 4 typhoon (SSHWS)

Peak intensity	175 km/h (110 mph)(10-min); 935 hPa (mbar)

On August 20, the JMA reported that a low-pressure area had formed near theMariana Islands.^[106] At midnight on August 21, both the JMA and the JTWC upgraded the tropical depression, with the latter designating the system as11W.^[107][108] Shortly after, the depression intensified into a tropical storm and was namedShanshan by the JMA due to low vertical wind shear and warm sea surface temperatures.^[107] A ragged eye-like feature appeared on satellite imagery, and on August 24,^[47] both the JMA and the JTWC upgraded it to a minimal typhoon.^[109] The JMA reported that Shanshan reached its peak intensity at 15:00 UTC on August 27, with 10-minute sustained winds of175 km/h (110 mph) and a central pressure of 935 hPa (27.61 inHg).^[107] Shanshan then turned northward and made landfall nearSatsumasendai inKagoshima Prefecture on August 29.^[107][110] It then turned eastward along the northern periphery of a subtropical high,^[111] quickly crossed theSeto Inland Sea, and made landfall over the northern tip ofShikoku on August 30.^[111] Shanshan's circulation later diminished as its LLCC became disorganized.^[111] However, convection slightly increased after six hours as Shanshan's circulation moved back over open water and began moving east-southeastward, causing to regenerate back to a depression.^[112][113] The JMA continued to monitor the system until it dissipated at 18:00 UTC that day.^[44]

The JMA issuedspecial weather warnings forKagoshima Prefecture, marking the first such emergency alert sinceTyphoon Nanmadol in2022.^[114] Shanshan caused six fatalities and damaged hundreds of structures throughout Japan.^[115] In response to the severe weather, evacuation orders were issued for 996,299 people in Miyazaki Prefecture and 982,273 people in Kagoshima Prefecture.^[116]

On August 30, the JMA reported the formation of a low-pressure area approximately 540 km (330 mi) northwest of Palau.^[44][117] This broad low-pressure system began to organize and developed into a tropical depression on August 31.^[44] The following day, PAGASA designated the system as a tropical depression and named itEnteng, as it formed within the Philippine Area of Responsibility.^[118] Shortly after, the system was classified asTropical Depression 12W.^[119] As it intensified into a tropical storm, the JMA named itYagi.^[119][107] At 14:00 PHT (06:00 UTC) on September 2, Yagi made landfall inCasiguran, Aurora.^[120] Early the next day, both the JMA and the JTWC upgraded the storm to a typhoon as satellite imagery revealed the formation of an eye. On September 5, Yagi reached peak intensity as a Category 5-equivalent super typhoon, with 1-minute sustained winds of 260 km/h (160 mph) and a central pressure of 915 mbar (27.0 inHg).^[119] It made landfall inWenchang City,Hainan, and passed directly overHaikou,China, before moving into the open waters of the Gulf of Tonkin and making landfall overXuwen County inGuangdong.^[119]On September 7, Yagi reorganized and restrengthened into a Category 4-equivalent typhoon before making its final landfall overHaiphong andQuảng Ninh,Vietnam.^[119] It continued to weaken rapidly as it moved southwest along the southeastern edge of a mid-level subtropical high,^[107] becoming a tropical depression on September 8. The JMA monitored Yagi until it was last noted at 18:00 UTC that day.^[121]

Yagi, combined with the effects of thesouthwest monsoon, resulted in at least 21 deaths, 22 injuries and 26 missing people in the Philippines.^[122] Yagi also caused extensive damages, landslides and floods in Vietnam, Laos, Thailand and Myanmar and left 815 people dead.^[123]

Tropical storm (JMA)

On September 2, theJapan Meteorological Agency noted that a tropical depression had formed over the open Pacific.^[124] Despite unfavorable conditions, JTWC later issued a TCFA warning, citing that it will intensify in the upcoming days. Two days later, the JTWC designated the system as Tropical Depression13W. A day later, JMA reported that it intensified into a tropical storm, assigning the nameLeepi. Although the storm was in a high wind shear and unfavorable environment, Leepi continued to maintain that intensity as it accelerated northeastward. Satellite imagery depicted that the low-level circulation center (LLCC) of Leepi passed under strong upper-level southwesterlyflow, indicated by a broad region of cirrus streamers. The storm did not last long, and JTWC later announced its final warning on September 6 as the system transitioned to an extratropical cyclone. The JMA later followed suit and issued its final advisory on 18:00 UTC of September 6.^{[citation needed]}

On September 20, a tropical depression formed near northern Luzon. The disturbance was in a marginal environment, with moderate to high wind shear and warm sea surface temperature. Hours later, JMA later recognized the LPA as a depression. At 14:00 PHT of the same day, PAGASA followed suit and named the system asIgme.^[157] JTWC later issued a TCFA warning as the LLCC started to organize. The next day, the JTWC upgraded Igme as a tropical depression and designated it as17W.^[158] Igme later curved southwestwards, passing closely throughTaiwan with the JMA last noting it as it became embedded in a front.^[158] On September 22, the JTWC reported that Igme had strengthened into a tropical storm as it neared China, though reanalysis showed that it remained as a depression throughout its track.^[158] JTWC later discontinued issuing bulletins on Igme after high vertical wind shear and the topographic interaction had caused to weaken significantly and dissipated after.^[159]

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	September 23 – September 27
Peak intensity	65 km/h (40 mph)(10-min); 998 hPa (mbar)

On September 24, a tropical depression formed south ofJapan, designated as18W by the JTWC later that same day. The following day, 18W was upgraded by the JMA to become a tropical storm, thereby earning the nameCimaron. JTWC later followed suit and upgraded into a storm as it moved westward. Cimaron later moved northeastward, with the presence of moderate and high shear, which caused a weakening of a tropical depression. The environmental analysis also depicted that Cimaron is in an unfavorable environment, characterized by moderate poleward outflow and the presence of dry air.^[160] At the latter part of September 27, JTWC reported that Cimaron became a remnant low due to its increasing vertical wind shear, resulted of eroding of the low-level circulation center (LLCC). The agency made its final warning as it absorbed within the frontal boundary.^[161] The JMA downgraded the system to a low-pressure area on 18:00 UTC of the same day.

Typhoon (JMA)
Category 1 typhoon (SSHWS)
Duration	September 25 – October 2
Peak intensity	120 km/h (75 mph)(10-min); 980 hPa (mbar)

On September 25, a tropical depression formed near theNorthern Mariana Islands. Later that day, JTWC started issuing advisories, stating that it would gradually intensify in the upcoming days. On September 26, it was classified as19W by the JTWC as it was in a marginally favorable environment.^[162] 19W developed into a tropical storm, thus gaining the nameJebi by the JMA. Satellite imagery shows that Jebi struggled to organize as moderate low-level wind shear was present.^[162] The storm was downgraded back into a depression on September 28. However, Jebi regained tropical storm status for the second time as it moved northeastwards. On October 1, Jebi further strengthened into a Category 1-equivalent typhoon according to the JTWC, while JMA retained severe tropical storm status. Both agencies later issued their final warning the next day, as Jebi became anextratropical cyclone.

Violent typhoon (JMA)
Category 4 super typhoon (SSHWS)
Duration	September 26 – October 3
Peak intensity	195 km/h (120 mph)(10-min); 920 hPa (mbar)

On September 26, the JMA reported a tropical depression 250 km (155 mi) south-southwest ofKadena Air Base,Japan,^[163] characterised by a partially exposed low-level circulation centre with persistent deep convection in the southern semicircle and formative banding to the north.^[44] On the next day, the PAGASA announced that the system had developed into a tropical depression, naming itJulian.^[164] At 09:00 UTC, the JTWC upgraded the tropical depression, designating the system as20W.^[165] On September 28, the depression intensified into a tropical storm namedKrathon by the JMA as it moves southwestward along the southeastern periphery of a mid-level subtropical high.^[107] Early the next day, both the JMA and the JTWC upgraded it to a minimal typhoon after it had opened a broad,raggedly-defined eye,^[166] which had since become cloud-filled.^[107] Early on October 1, the JMA upgraded Krathon to aviolent typhoon, estimating its peak intensity with a minimum centralpressure of 915 hPa (27.02 inHg) and 10-minute maximum sustained winds of195 km/h (120 mph).^[107] On October 3 at 12:40 p.m. local time, Krathon made landfall nearSiaogang District inKaohsiung, Taiwan as a weakening Category-1 typhoon.^[167] After making landfall, the system rapidly slowed down and deteriorated, weakening rapidly to a depression.^[168] The JMA continued to monitor the system as it emerged into the South China Sea before dissipating on October 4.^[44][107]

Krathon caused landslides and flooding in parts of the Philippines, leaving five people dead and another missing. Eight others were injured.^[169] Four deaths, 714 injuries and one missing person was also reported in Taiwan.^[170]

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	October 4 – October 11
Peak intensity	85 km/h (50 mph)(10-min); 985 hPa (mbar)

A tropical depression formed near Guam on October 5. The following day, the JTWC issued a TCFA on the system and later upgraded it to Tropical Depression21W. With convection flaring and persisting to the east of a partial low-level circulation center, the JTWC upgraded it to a tropical storm on October 7. Despite moving over warm waters, high wind shear further displaced the convection, weakening 21W to a tropical depression a few hours later. On October 8, the JTWC issued its last warning on 21W as it further weakened, with the agency expecting it to dissipate within the next 12 hours. The next day, the JMA upgraded 21W to a tropical storm, naming itBarijat. After a few hours, the JTWC reissued warnings for it. However, Barijat would begin its extratropical transition, prompting the said weather agency to issue its last warning the following day, at 09:00 UTC.

Severe tropical storm (JMA)
Category 1 typhoon (SSHWS)
Duration	October 18 – October 29
Peak intensity	110 km/h (70 mph)(10-min); 970 hPa (mbar)

On October 17, the JMA reported a low-pressure area located 633 km (394 mi) west of Guam. The low-pressure area later moved westward slowly before it was designated as a tropical depression by the JMA.^[44] The following day, the JTWC designated the system as22W, as low-level banding wrapped into the circulation center.^[171] At 18:00 UTC that day, the JMA upgraded the system to a tropical storm and named itTrami.^[107] At around 06:00 UTC on October 23, the JMA reported that Trami had intensified into a severe tropical storm as it was moving west-northwestward along the southwestern edge of a mid-level subtropical high,^[107] At 12:30 AM PHT of October 24 (16:30 UTC on October 23), the storm made landfall inDivilacan, Isabela,^[172] The following day, Trami emerged over the coastal waters of southernIlocos Sur and encountered easterly vertical wind shear as it approached the coast of Vietnam.^[173] It made landfall inThua Thien-Hue andDa Nang at about 10 AM local time on October 27,^[174] before drifting slowly inland while moving southwestward over the past few hours.^[175] The storm rapidly weakened as it moved around theLaos–Vietnam border.^[107] It then moved southwestward before making a U-turn and gradually moving toward the coastal regions of Vietnam.^[176] The JMA continued to monitor the system, which further weakened into a low-pressure area at 18:00 UTC the following day.^[44]

Overall, Trami was responsible for 178 deaths, with 23 people reported missing and 151 others injured, causing approximately US$426 million in damages.^[177] In Vietnam, Trami's strong winds caused trees and billboards to fall inDa Nang,^[178][179] while heavy rainfall inQuang Tri province resulted in severe flooding of several bridges and left 18,000 people without power.^[180]

Very strong typhoon (JMA)
Category 5 super typhoon (SSHWS)
Duration	October 24 – November 1
Peak intensity	185 km/h (115 mph)(10-min); 925 hPa (mbar)

On October 22, the JTWC started monitoring a weak exposed low-level circulation at14°54′N141°24′E / 14.9°N 141.4°E /14.9; 141.4, about 394 km (245 mi) west-northwest of Guam.^[181] The JMA designated the disturbance as a low-pressure area the following day,^[44] and on October 24, it was upgraded to a tropical depression.^[107] At 00:00 UTC on October 25, the JMA upgraded the system to a tropical stormnamedKong-rey,^[107] which the JTWC later designated as23W. On October 30, the JTWC reported that the system had peaked as a Category 4-equivalent super typhoon after Kong-rey attained 1-minute sustained winds of240 km/h (150 mph),^[182] and a 10-minute sustained winds of185 km/h (115 mph) and a centralpressure of 925 hPa (27.32 inHg).^[107] The following day at 1:40 p.m. local time, Kong-rey made landfall inChenggong, Taitung in eastern Taiwan.^[183] It was later reemerged over theTaiwan Strait with a weakened convective structure, and its rapid movement across Taiwan may be attributed to a lee-side jump.^[184] It moved along the eastern coast of China as it began its extratropical transition^[185] On November 1, JMA reported that Kong-rey had transitioned into an extratropical low as it moved north-northeastward, with JTWC alongside discontinued the warnings as it completed its extratropical transition.^[186]

Kong-rey triggered strong winds and storm surges that flooded several houses inGonzaga, Cagayan and Batanes,^[187] and destroyed the historicItbayat Church, the oldest church inItbayat, Batanes.^[188] In Taiwan, typhoon warnings were issued all around the country.^[189] Multiple large wave warnings and a singular surge warnings were issued, all in the eastern coast of Taiwan.^[190] At least three people were killed and 690 others were injured in Taiwan.^[191]

Very strong typhoon (JMA)
Category 4 super typhoon (SSHWS)
Duration	November 2 – November 12
Peak intensity	185 km/h (115 mph)(10-min); 945 hPa (mbar)

Yinxingemerged from an area of convection 494 km (307 mi) east ofYap, with satellite imagery showing the lower-level winds beginning to consolidate as the convective banding wrapped around the low-level circulation center on November 2.^[192] At 00:00UTC the following day, theJapan Meteorological Agency (JMA) classified the system as a tropical depression. Later that day, the JTWC designated the system as24W due to its compact structure and a small burst of deep convection occurring near the circulation center.^[193] At 18:00 UTC the same day, the JMA upgraded the system to a tropical storm namedYinxing,^[107] as it exhibited improved convective banding tightly wrapping around the obscured LLCC.^[194]

On November 7, the JTWC reported that the system had peaked as a Category 4-equivalentsuper typhoon after Yinxing attained 1-minutesustained winds of240 km/h (150 mph),^[195] while the JMA indicated that it reached its peak intensity with 10-minute sustained winds of175 km/h (110 mph) and a centralpressure of 940 hPa (27.76 inHg).^[107] Later that day, Yinxing madelandfall onSanta Ana, Cagayan on Luzon island around 3:40 PM PHT (07:40 UTC).^[196] After crossing theBabuyan Channel, Yinxing made its second landfall inSanchez Mira, Cagayan, also on Luzon, at 9:00 PM PHT (13:00 UTC).^[197] As the typhoon accelerated westward over theSouth China Sea, it weakened due to terrain interaction.^[198] Yinxing later restrengthened with an oblong eye and an 11.8 °C eye temperature, prompting the JTWC to estimate winds at 205 km/h (125 mph) on November 9. By the next day, Yinxing began weakening as cooler sea surface temperatures (around 26 °C) and increasing wind shear disrupted its structure. Moving southwest between two subtropical highs, strong shear exposed its low-level circulation. The system maintained a compact center near southern Vietnam, with limited convective activity.^[199] The JMA tracked Yinxing until it dissipated at 18:00 UTC on November 12.^[200]

Violent typhoon (JMA)

Man-yi emerged from an area of convection 220 km (140 mi) east ofKwajalein Atoll, with satellite imagery showing a more organized low-level circulation center and a persistent area of deep convection on the southwestern periphery on November 8.^[201] The JMA designated the disturbance as a low-pressure area on the same day,^[44] and the next day, it was upgraded to a tropical depression.^[107] Later that same day, the JTWC assigned the system the designation25W, noting that it was a consolidating system with formative bands wrapping in from the north. Moving northwestward, the JMA upgraded the system to a tropical storm namedMan-yi at 06:00 UTC on the same day.^[107] The system became disorganized as it passedGuam on November 13.^[202]

Two days later, Man-yi began to strengthen whilst almost simultaneously being assigned the namePepito by thePAGASA agency. Shortly after Man-yi began its intensification period, it was upgraded to a typhoon.^{[citation needed]} Just one day later, the JTWC upgraded the system to super typhoon status, with estimated 1-minute maximum sustained winds of260 km/h (160 mph), making it a Category 5-equivalent super typhoon.^[203] Meanwhile, the JMA upgraded Man-yi to aviolent typhoon, estimating its peak intensity with aminimum central pressure of 920 hPa (27.17 inHg) and 10-minute maximum sustained winds of195 km/h (120 mph).^[107] Man-yi made its first landfall inPanganiban, Catanduanes at around 9:40 PMPHT (13:40 UTC).^[204] After making landfall in Catanduanes, the system’s appearance slightly degraded as it passed north of theCalaguas Islands.^[205][206] The following day, Man-yi made its second landfall inDipaculao, Aurora on Luzon Island at around 3:20 PM PHT (07:20 UTC) and quickly moved inland.^[10][207] Man-yi accelerated northwestward over the South China Sea, rapidly deteriorating as the storm experienced a low-level northeasterly cold surge and increased vertical wind shear.^[208][209] The JTWC issued its final warning on the same day as the system weakened to a tropical depression, while the JMA continued to monitor it until it was last noted at 06:00 UTC on November 20.^[44]

Typhoon (JMA)
Category 1 typhoon (SSHWS)
Duration	November 8 – November 15
Peak intensity	130 km/h (80 mph)(10-min); 980 hPa (mbar)

On November 8, the JMA reported that alow-pressure area had formed 620 km (386 mi) north ofYap,^[44] Environmental analysis indicated a favorable environment for further development, withsea surface temperatures of 30–31 °C (86–88 °F), strong poleward outflow aloft, and low vertical wind shear.^[201] At 18:00 UTC on the same day, the JMA classified the system as a tropical depression.^[44] At 06:00 UTC the same day, the JMA upgraded the system to a tropical storm namedToraji,^[107] which the JTWC later designated as26W.^[210] Satellite imagery shows that Toraji was undergoingrapid intensification, with a small system displaying an elongated, compact CDO feature, measuring around 81–92 miles (130–148 km) in diameter. Amicrowave imaging reveals a complete eyewall surrounding a small microwaveeye feature, along with a deep convective band over the southern quadrant.^[211]

Early the next day, the JMA upgraded it to a severe tropical storm as it moved west-northwestward, with formative bands wrapping tighter around the obscured low-level circulation.^[107][212] At 09:00 UTC on that day, the JTWC upgraded the storm to a minimal typhoon, noting a more asymmetric CDO in the eastern quadrant.^[213] Satellite imagery reveals a decrease in easterly vertical wind shear, with the CDO becoming more symmetric and building back over the low-level circulation center.^[214] At 15:00 UTC on the same day, the JMA upgraded Toraji to a typhoon.^[107] On November 11, Toraji madelandfall onDilasag, Aurora, on Luzon Island at around 8:10 AM PHT (00:10 UTC),^[215] before moving inland over mountainous terrain, which caused significant weakening.^[216] Satellite imagery showed a weakening of deep convection at the storm's center, resulting from strong southerly vertical wind shear as it became embedded in the low-level northeasterly flow associated with a cold surge.^[217][218] The JMA continued to monitor the system until it was last noted at 06:00 UTC on November 15.^[44]

Peak intensity	55 km/h (35 mph)(10-min); 1004 hPa (mbar)

After a month of inactivity, at 15:00 UTC on December 16, the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert, designating the system asInvest 96W.^[224] The next day, it became a depression and entered thePhilippine Area of Responsibility, which PAGASA namedQuerubin,^[225] a replacement name forQuinta. On 17:00 PHT (09:00 UTC), PAGASA declared Signal No. 1 toDavao Oriental.^[226] Six hours later, the JTWC issued a TCFA to Querubin, citing that it will strengthen for the next couple of days. Satellite imagery shows the banding organizing, with Querubin inside a favorable environment.^[227] At 11:00 PHT (03:00 UTC) in December 18, PAGASA also placed Signal No. 1 inSurigao del Sur.^[228] At 17:00 PHT (09:00 UTC), PAGASA downgraded it to a low pressure area.^[229] On 13:00 UTC, JTWC cancelled TCFA for the system. However, the agency reissued it for the second time on 19:30 UTC, citing a high chance of formation of a tropical cyclone. Later that day JTWC cancelled the TCFA and downgraded it to a low chance before dissipated. Its remnants' energy later re-formed into Pabuk.

Tropical storm (JMA)

Peak intensity	65 km/h (40 mph)(10-min); 1000 hPa (mbar)

On December 20, the JMA reported a low-pressure area located 460 km (290 mi) west-southwest ofBrunei,^[44] which was later upgraded to a tropical depression.^[44][230] At 06:00 UTC the following day, the JTWC issued a TCFA, noting that formative banding was organizing around the circulation and deep convection was building over the center.^[231] However, due to its imminent threat to the Kalayaan Islands, PAGASA named the depressionRomina, a replacement name forRolly, even though it was still outside the PAR, at 11:00 PHT (03:00 UTC) on December 22, and began issuing advisories on it.^[232] This marked the first time since 1963 that PAGASA named a tropical cyclone outside the PAR.^[233] Later that same day, the JTWC assigned the system the designation28W, noting a strong northeast surge was occurring with winds shifting from north-northeasterly to northerly, whileInvest 98W, which had formed near the storm, rapidly weakened and was absorbed into the storm's southeastern periphery.^[234] Pabuk showed deep convection flaring on the northwestern periphery of a low-level circulation that was mostly exposed.^[235] On December 23, PAGASA issued its final advisory on Romina as it moved away from the Kalayaan Islands and lifted the wind signals.^[236]

On 06:00 UTC, the JMA upgraded the storm to a tropical storm and named itPabuk, following the observation of a favorable environment as it moved westward along the southern periphery of a mid-level subtropical high.^[107] Pabuk moved westward and turned toward Vietnam as it lost its vertical structure, steered by the low-level flow associated with a northeasterly cold surge along the eastern coast of Vietnam.^[237] The system was last noted by the JMA on 18:00 UTC of December 25.

• On August 18, the JMA reported the formation of a low-pressure area over thePhilippine Sea.^[44] The next day, it was designated as a tropical depression but weakened to a low-pressure area by August 22.^[44] The following day, the JMA re-designated it as a tropical depression as it turned southward.^[44] Over the next few days, the depression gradually moved southwestward whileTyphoon Shanshan approached Japan from the west.^[44] The JMA continued to monitor the depression until it dissipated on August 26.^[44]
• A tropical depression briefly formed south ofSouth Korea on August 19 and was last noted by the JMA at 18:00 UTC as it moved northward.^[44][44]
• A tropical depression briefly developed southeast ofJapan on August 20.^[106] Thereafter, it was designated as an extratropical low while drifting southeastward.^[44]
• A tropical depression briefly formed southeast of Typhoon Shanshan on August 30 and was last noted by the JMA at 18:00 UTC.^[44][44]
• On September, formerHurricane Hone moved into the basin from the Central Pacific. At that time, it was classified as a tropical depression by the JMA and as a subtropical depression by the JTWC the next day.^{[238][124][239]} The depression persisted for several days, and was tracked by the JMA until September 8.^[240]
• A tropical depression formed over the Philippine Sea on September 4. Two days later, it degenerated into a low-pressure area as it slowly turned to the west. On September 9, it re-strengthened back into a tropical depression as it moved west-northwest towards Eastern China where it made landfall before dissipating.
• On September 25, the JTWC marked a subtropical storm nearTokyo and designated it with an invest tag96W, stating the system has a low chance of transitioning to a tropical system. The next day, the agency last noted the system as it merged with a frontal boundary while moving to the east. The JMA did not recognize the system.
• A tropical depression formed west ofGuam on September 26. The depression did not last long, dissipating the next day, with its remnants moving northwards across the Philippine Sea.
• Another tropical depression formed west ofGuam on October 6. The depression moved eastwards as it interacted with a nearby tropical depression that would later become Tropical Storm Barijat. The JMA last noted it the next day as the depression became embedded in the latter's circulation.
• A tropical depression formed in northeast of Mukojima on October 12. JTWC classified it as a subtropical depression on October 13. JTWC upgraded it into a subtropical storm on October 14. At the same time, JMA declared the system had transitioned to a developing extratropical low.
• A tropical depression formed north of Micronesia on October 16. The depression did not last long, and JMA downgraded the system into a low pressure area the next day.

Within the basin, both theJapan Meteorological Agency (JMA) and thePhilippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names.^[241] The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of theWorld Meteorological Organization's Typhoon Committee when they have 10-minute sustained winds of 65 km/h (40 mph).^[242]

PAGASA names tropical cyclones which are active in theirarea of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has already been named.^[241] If the list of names for the Philippine region are exhausted, then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked ingray. The names of significant tropical cyclones were retired by bothPAGASA and theTyphoon Committee in the spring of 2025.^[242]

During the season, 26 tropical storms developed in the Western Pacific and all of them were named by the JMA once they had 10-minute sustained winds of 65 km/h (40  mph).^[243] The JMA selected the names from a list of 140 names, that had been developed by the 14 members nations and territories of theESCAP/WMO Typhoon Committee.^[244] Retired names, if any, will be announced by theWMO in 2025, though replacement names will be announced in 2026. During the season, the namesPulasan,Krathon andYinxing were used for the first (and only, in the case ofKrathon) time after they replacedRumbia,Mangkhut andYutu, which were retired following the2018 season.

At their 57th Session in February 2025, the ESCAP/WMO Typhoon Committee announced that the namesEwiniar,Yagi,Krathon,Trami,Kong-rey,Toraji,Man-yi andUsagi would be retired from the naming lists, and they will never be used again for another typhoon name. Additionally, the nameJebi was also retired due to its pronunciation being identical to that of a derogatory word inCroatian.^[245] The replacement names will be announced in early 2026. With nine names retired, this surpassed the previous record for the number of typhoon names retired after a single season – six, held by the2022 season.

If a tropical cyclone enters the Western Pacific basin from theEastern and Central Pacific basin (west of 180°E), it will retain the name assigned to it by theNational Hurricane Center (NHC) andCentral Pacific Hurricane Center (CPHC). The following storms were named in this manner.

• Hone

During the season, PAGASA used its own naming scheme for the 18 tropical cyclones, that either developed within or moved into their self-defined area of responsibility.^[246] The names were taken from a list of names, that was last used during2020 and are scheduled to be used again during 2028.^[246] All of the names are the same exceptAghon,Querubin,Romina andUpang which replaced the namesAmbo,Quinta,Rolly andUlysses after they were retired.^[246] The namesAghon,Querubin, andRomina were used for the first (and only, in the case ofAghon) time this year.

On February 20, 2025, PAGASA announced that the namesAghon,Enteng,Julian,Kristine,Leon,Nika,Ofel, andPepito would be retired from the naming list, after they all caused over₱1 billion in damages to the Philippines. They will be replaced on the naming list withAmuyao,Edring,Josefa,Kidul,Lekep,Nanolay,Onos andPuwok respectively. These new names will first be used in the 2028 season.^[247]

With a total of eight names, this set a new record of names retired in a single season since the beginning of its current naming system in 2001, surpassing the previous record of five names, held by the2011 and2014 seasons.^{[248][249][250]}
