The1855 Atlantic hurricane season featuredtropical cyclonelandfalls in theGulf Coast of the United States, theGreater Antilles, and Mexico, but none along theEast Coast of the United States. It was inactive, with only five known tropical cyclones. Another tropical storm was believed to have existed offshoreAtlantic Canada in late August and early September,[1] butHURDAT – the official Atlantic hurricane database – now excludes this system.[2] The first known system was initially observed on August 5, while the final known storm was last noted on September 17. These dates fall within the period with the most tropical cyclone activity in the Atlantic. At one point during the season, two tropical cyclones existed simultaneously. Two of the cyclones only have a single known point in their tracks due to a sparsity of data.
Of the season's five tropical cyclones, four reached hurricane status. Furthermore, one of those four strengthened into amajor hurricane, which are Category 3 or higher on the modern-daySaffir–Simpson scale. The strongest cyclone of the season, the fifth system, peaked at Category 3 strength with 125 mph (205 km/h) winds. It reportedly produced some of the worst impacts inLouisiana andMississippi since1819 and killed at least one person in the latter. The first storm of the season brought locally severe impact toTampico, Tamaulipas, in Mexico in early August. Additionally, the fourth storm caused severe damage in theLesser Antilles.
| Category 2 hurricane (SSHWS) | |

| Duration | August 6 – August 6 |

| Peak intensity | 105 mph (165 km/h)(1-min); |
Based on newspaper reports,[3] the first hurricane of the season was within the vicinity ofTampico, Tamaulipas, on August 6. Maximum sustained winds were at 105 mph (165 km/h), indicating a Category 2 hurricane.[2] No further information is available on the meteorological history of this storm. However, it is possible that the storm developed in the Caribbean in late July, due to data obtained from thebarqueBercaldine.[4] Torrential rainfall in the Tampico area caused disastrous flooding, with heavy damage to goods and property. Eleven vessels were docked at Tampico, some of which lost their cargo. At the mouth of thePánuco River, apilot station and a fort were swept away. The event was considered the worst inundation of Tampico over the last 30 years.[3]

The shipJames Foster Jr. encountered a hurricane on August 10,[4] while located about 575 mi (925 km) east-southeast ofCape Race,Newfoundland. Sustained winds of 105 mph (165 km/h) were observed, equivalent to a Category 2 hurricane.[2] Data from theJames Foster Jr. andRebecca indicate that the storm moved rapidly northeastward.[5] This system was last noted about 560 mi (900 km) west of Ireland on August 11.[2] Climate researcher Michael Chenoweth proposed the removal of this storm from HURDAT, noting "Insufficient supporting evidence from other neighboring data sources".[6]
| Category 1 hurricane (SSHWS) | |
 | |
| Duration | August 11 – August 11 |
|---|---|
| Peak intensity | 80 mph (130 km/h)(1-min); |
HMSWalverine reported a hurricane at 12.5°N, 83.0°W, which is located about 15 mi (25 km) north ofNicaragua'sCorn Islands.[5] A sustained wind speed of 80 mph (130 km/h) was observed.[2] Shortly thereafter, HMSWalverine was wrecked and no further information is known about this storm.[5] Chenoweth also argued for the exclusion of this cyclone from HURDAT, noting that logbooks do not seem to indicate the presence of the storm andWalverine actually sank due to crashing into rocks for reasons unrelated to weather.[6]
| Tropical storm (SSHWS) | |
 | |
| Duration | August 24 – August 27 |
|---|---|
| Peak intensity | 70 mph (110 km/h)(1-min); 997 mbar (hPa) |
Based on reports of a strong gale,[5] a tropical storm was first tracked about 250 mi (400 km) east-southeast ofBarbados early on August 24. It initially headed westward, before re-curving west-northwestward early on the following day. Shortly thereafter, the storm passed through theWindward Islands betweenGrenada andSaint Vincent and the Grenadines. The storm peaked with winds of 70 mph (110 km/h) while moving northwestward across the Caribbean Sea. It weakened slightly before making landfall nearSan Pedro de Macorís,Dominican Republic, with winds of 60 mph (95 km/h) early on August 27. The storm slowly weakened overHispaniola and was last noted nearBombardopolis,Haiti, later that day.[2]
Considerable damage occurred in theLesser Antilles. OnSaint Vincent, rains destroyed roads and a number of houses. Many sugar cane fields were also ruined. Several vessels were lost there and on other islands, including Barbados,Dominica, andMartinique. OnSaint Croix in the present-dayUnited States Virgin Islands, at least one vessel was destroyed by the heavy gales. There were also strong gales reported inPuerto Rico and the Dominican Republic.[5]
| Category 3 hurricane (SSHWS) | |

The Middle Gulf Shore Hurricane of 1855
The shipOrphan encountered a hurricane with winds of 80 mph (130 km/h) in the central Gulf of Mexico on September 15.[7] It strengthened quickly while moving northward, becoming a Category 2 hurricane later that day. By 00:00 UTC on September 16, the storm peaked as a Category 3 hurricane with maximum sustained winds of 125 mph (205 km/h), making it the strongest tropical cyclone of the season. Shortly thereafter, the hurricane made landfall nearBuras-Triumph, Louisiana, at the same intensity.[2] Based on the pressure-wind relationship, the storm had a minimum barometric pressure of approximately 945 mbar (27.9 inHg) upon striking the coast.[8] It weakened after moving inland, decreasing to Category 1 intensity later on September 16. Early on the following day, the system weakened to a tropical storm, several hours before dissipating over centralAlabama.[2]
This was regarded as the worst hurricane in the region since1819. In Louisiana, winds and storm surge impacted the eastern portions of the state. The wharf and bathhouse in Proctorville were swept away. About 4 ft (1.2 m) of water was reported at Proctor's Landing. A combination of strong winds and storm surge destroyed a number of houses along the shores ofLake Borgne. Along the coast of Mississippi, most structures were swept to sea.[9] The foundation of theBiloxi Lighthouse was endangered due to erosion from this storm.[10] Additionally, locals described theCat Island Lighthouse as being left in "severe peril". Several ships were damaged or capsized in theMississippi River, includingAtchafalaya,J.S. Chenoweth,Ship Shoal, andVenice.[9][11] One death occurred inMississippi City after winds unroofed some lodging at the Teagarden Hotel,[12] while two women may have drowned along the coast of the state.[13]
In addition to the five tropical systems, another storm was operationally believed to have existed in late August and early September. The shipAtlantic encountered a very heavy gale while located west ofSable Island,Nova Scotia, on August 31.The storm moved rapidly east-northeastward offshore Atlantic Canada.[1] It was last noted on September 2, when the storm transitioned into anextratropical cyclone.[14] However, HURDAT no longer includes this system in its database.[2]
This is a table of all of the known storms that formed in the 1855 Atlantic hurricane season. It includes their duration (within the basin), areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm wasextratropical, awave, or alow, and all of the damage figures are in 1855 USD.
