The1944 Jamaica hurricane was a deadly major hurricane that swept across theCaribbean Sea andGulf of Mexico in August 1944. Conservative estimates placed the storm's death toll at 116. The storm was already well-developed when it was first noted passing westward over theWindward Islands into theCaribbean Sea on August 16. A ship nearGrenada with 74 occupants was lost, constituting a majority of the deaths associated with the storm. The following day, the storm intensified into a hurricane, reaching its peak strength on August 20 withmaximum sustained winds of 120 mph (195 km/h). At this intensity, the major hurricane madelandfall on Jamaica later that day, traversing the length of the island. The damage wrought was extensive, with the strong winds destroying 90 percent of banana trees and 41 percent of coconut trees in Jamaica; the overall damage toll was estimated at "several millions of dollars". The northern coast of Jamaica saw the most severe damage, with widespread structural damage and numerous homes destroyed across several parishes. InPort Maria, the storm was considered the worst since1903.
Land interaction weakened the hurricane, and the storm maintained this lessened intensity as it passed theCayman Islands, producing measured gusts of 80–90 mph (130–140 km/h). On August 22, the hurricane moved ashore theYucatán Peninsula nearCozumel and eventually emerged into theBay of Campeche as atropical storm. On August 24, the storm made landfall for a final time nearTampico, Mexico, bringing with it heavy rains that caused flooding throughout the coasts ofVeracruz andTexas, killing 12. The storm dissipated over the mountainous terrain of inland Mexico later that day. Heavy rains were reported across theRio Grande Valley, causing minor flooding. A tornado produced by the storms killed one person inMcCook, Texas and injured fifteen others.
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionOn August 16, 1944, decreasedpressures just east ofBarbados were indicative of a passingtropical storm.[1][2] The storm's first entry in theofficial Atlantic hurricane database lists the system as already possessing winds of 50 mph (80 km/h);[3] theAtlantic hurricane reanalysis project noted that the possibility that the tropical cyclone forming east of theLesser Antilles remains ambiguous due to a lack of observations over the open Atlantic. Not long after its first detection, the tropical storm intensified into a hurricane on August 17 as it crossed into theCaribbean Sea nearGrenada. Gradual intensification took hold as the storm progressed west-northwestwards across the Caribbean.[2] A ship en route toBuenos Aires, Argentina crossed theeye of the hurricane 180 mi (290 km) south ofPuerto Rico the following day, recording a central pressure of 973 mbar (hPa; 28.73 inHg); this was the lowest pressure measured in connection with the storm.[4] On the following day, the small tropical cyclone strengthened into the equivalent of aCategory 3 hurricane on the modernSaffir–Simpson hurricane wind scale, making the storm amajor hurricane.[2]
At around 16:00 UTC on August 20, the hurricane madelandfall in the vicinity ofBoston Bay along the coast ofJamaica with winds of 120 mph (195 km/h). At landfall, the hurricane's eye spanned 5 mi (8.0 km) across, resulting in a 15–20 minute lull in winds over eastern portions of Jamaica as the eye passed overhead.[2] The storm traversed the island over several hours, emerging nearMontego Bay by 23:00 UTC that day as a weakened system equivalent to a Category 1 hurricane.[2][3] The storm largely maintained its strength in the western Caribbean Sea, passing nearGrand Cayman on August 21 with the same intensity with which it departed from Jamaica.[1][3] The following morning, the hurricane struck theYucatán Peninsula nearCozumel Island and degenerated into a tropical storm over the peninsula. Despite reemerging over theBay of Campeche, weakening continued; the system ultimately moved ashore nearTuxpan, Mexico as a minimal tropical storm early on August 24 before dissipating inland later that day.[2]

On August 19, theUnited States Weather Bureau issued a hurricane alert for Jamaica and advised precaution to points in the Caribbean west and northwest of the island.[5] Waves began buffeting the Jamaican coast in advance of the storm: a "very heavy" swell was noted alongPalisadoes with the center still 70 mi (110 km) away.[2] Early reports, although scant, suggested that the hurricane was one of the most significant in Jamaica's history, with no comparable storm in the preceding two decades.[6] The most powerful effects were felt in theBlue Mountains,[6] resulting in a swath of devastation on the northern shore of Jamaica.[7] The island sustained heavy losses to its banana and coconut crop, with an estimated damage toll of several millions of dollars. An estimated 90 percent of banana trees and 41 percent of coconut trees were lost.[1] These crops were primarily located in the parishes ofClarendon,Portland,Saint Thomas,Saint Catherine, andTrelawny, as well as in theMontego Bay valley.[7] Within the core coconut-producing region between Saint Thomas and Saint Ann, 30 percent of coconuts were either blown down or destroyed.[8] Entire coconut plantations were denuded by the strong winds.[1] Heavy rains caused the reservoir atHermitage Dam to overflow—the reservoir's water level was initially 53 ft (16 m) below the spillway. The 10.88 in (276 mm) of rainfall measured in the dam's watershed was a record for the area.[9]
In total, over 30 fatalities occurred in Jamaica, primarily as a result of the hurricane's strong winds. The severest damage was inflicted upon Portland,Saint Ann, andSaint Mary parishes.[2] Five people were killed and many others reportedly injured in Saint Mary Parish.[10] Numerous homes were destroyed in the parish, leaving hundreds of people displaced.[11] In the parish's capital town ofPort Maria, nearly all buildings sustained damage and hundreds of people including infants and schoolchildren required immediate assistance;[10][7] a hospital was destroyed in nearbyAnnotto Bay,[10] injuring 40 people.[7]The Daily Gleaner called the hurricane Port Maria's worst storm since1903, as an estimated 75 percent of buildings in the town were at least heavily damaged. The parish's church sustained significant damage, with both of itstransepts unroofed andclergy house destroyed.[12] The overturning of two 14.5 long tons (14.7 t) railway cars in Annotto Bay suggested that winds reached 100–120 mph (160–190 km/h) there.[2] Acopra factory in the adjacent communities of Frontier and Wentworth was also badly damaged.[12]
At least six people were killed in Saint Ann Parish. Most homes located on the parish waterfront were destroyed. InSaint Ann's Bay, the court house and parish church all sustained heavy damage. Sugar stores and factories in the town were damaged.[13]Port Antonio in Portland Parish was heavily damaged by the hurricane—nearly all buildings were damaged, with most flattened and others unroofed.[7] Several public buildings, including the city's town hall and court house, were either damaged or destroyed.[14] A five-wardpoorhouse was destroyed and several schools lost their roofs.[7] Two people were killed in the port by flying debris.[12] All telecommunication lines were downed in Port Antonio and electricity and transportation service was hampered.[14] Virtually all homes inBuff Bay were damaged, and three churches were destroyed. Ninety-five percent of coconut trees in the settlement were blown down, as well as local banana and breadfruit plantations. Many other communities in Portland Parish suffered similar effects, reporting the destruction of most of their buildings;[7] thousands were left homeless.[14] TheMember of Parliament for the parish, H. E. Allen, conservatively estimated the number of homeless persons at 6,000, along with the complete loss of the banana industry and significant loss to coconut trees.[15] Three people were killed and several others injured in Skibo, with considerable losses to livestock reported throughout the parish.[7] AtFamouth inTrelawny Parish, the Rose Hall Sugar Factory lost its chimney, and a police station 2 mi (3.2 km) away was destroyed; 500–600 people were rendered homeless in the parish. Other communities in Trelawny reported numerous destroyed homes and an 80–100 percent loss of bananas.[16] Small houses were destroyed and a girls' school severely damaged in Montego Bay inSaint James Parish by 60 mph (97 km/h) winds, with the storm's severest effects lasting for roughly two hours. One indirect death was reported in the city.[17]
Winds in the capital city ofKingston topped out at 60 mph (97 km/h).[1] Damage to buildings in the capital city was relatively minor,[18] though transportation and electrical service was disrupted. Fallen trees and fencing tore wires and laid across tramways and streets. Flooding rivers exacerbated the traffic disruptions, submerging or destroying bridges across several parishes.[7] Communications between Kingston and the rest of Jamaica were also severed.[19] Elsewhere in Saint Andrew Parish, widespread crop and infrastructure damage occurred in Swains Spring, Coopers Hill, and Padmore.[7] AtSpanish Town in Saint Catherine Parish, trees were uprooted and communications lost between the town and Kingston. While businesses there otherwise avoided significant impacts, their roofs were damaged.[20] Most homes and plantations were destroyed in districts in western Saint Andrew Parish, displacing hundreds of people.[21]
Following the storm,The Daily Gleaner initiated a relief fund to aid in the storm's aftermath;[22] the fund was later managed by the Central Council of Voluntary Social Services.[23] On August 22,Governor of JamaicaSir John Huggins compelled a conference atHibbert House with all heads of the colony's ministries, establishing a Central Relief Committee to coordinate with local relief operations and serve as the government's principal communications channel vis-à-vis hurricane relief.[24]
Across the Caribbean outside of Jamaica, the hurricane's effects were scattered. A British vessel nearGrenada with 74 people on board was lost. Gusts of 80–90 mph (130–140 km/h) swept over theCayman Islands.[1] One station documented a gust of 90 mph (140 km/h) early on August 21.[2] A ship was lost off the Yucatán Peninsula, though information on its crew and effects was unknown. Twelve people were killed inVeracruz as a result of flooding from the hurricane's third and final landfall near Tuxpan.[1][25] Others–their numbers unknown–were missing following a surge ofmeltwater fromPico de Orizaba triggered by the tropical storm.[25] Communication lines were downed inTampico, delaying early damage reports.[26]
The U.S. Weather Bureau issued a storm warning for the lowerTexas coast fromMatagorda Bay toBrownsville, anticipating that the hurricane would eventually make landfall in the Brownsville area. Aircraft stationed at coastal airfields were moved farther inland, and small craft northwards to theLouisiana coast were brought to port.[27] The passing storm brought heavy rains to theRio Grande Valley, with rainfall totals reaching over 5 in (130 mm) in Brownsville.[28][29]Roma reported 5.1 in (130 mm) on the night of August 22, marking the first rainfall event of that magnitude in nearly a decade. A slightly rain-swollenRio Grande resulted in minor flooding downstream, disrupting transportation between the United States–Mexico border southward toMonterrey, Mexico.[28] Projections suggested that a few hundred acres of crops in the immediate floodplain would be inundated, with marginal effects elsewhere. Five oil wells inWilacy County were suspended after the flooding cut off their water supplies.[30] A tornado struckMcCook, killing one person and injuring fifteen others; fourteen of the injured were located in a single home. Crop damage was also reported in connection with the tornado.[31]
