Through Flood, Cuba and Atmospheric circulation

Heavy rainfall was reported in Jamaica, with as much as 36 inches (910 mm) of precipitation recorded in some areas. Several bridges were severely damaged in the northern and eastern portions of the island. Strong winds generated by the storm destroyed approximately 25% of banana trees, while telegraph lines were downed in a number of places. Railway lines were also heavily damaged by the winds and rain. Rough seas also lashed the island, with Savanna-la-Mar suffering near complete destruction and 42 deaths in that city alone. Across western Jamaica, roughly a hundred homes were destroyed, while 5,000 buildings were damaged or demolished. About 100 fatalities and $1.5 million (1912 USD) in damage occurred in Jamaica. Extensive flooding and five fatalities occurred in Cuba in the Guantánamo Bay area.

Meteorological history

The origins of the 1912 Jamaica hurricane can be definitively traced to a low-pressure area first identified on November 10 in the central Caribbean Sea, south of Hispaniola. Although a tropical wave that crossed the Lesser Antilles several days prior was believed to be a possible precursor to the hurricane, this could not be fully concluded due to the lack of observations in the eastern Caribbean Sea. Early on November 11, the development of a closed atmospheric circulation led to the classification of a tropical storm about 110 mi (180 km) north of Cacique, Colón, in Panama at 06:00 UTC that day. Decreasing barometric pressures in the region confirmed the presence of a cohesive and developing system. The tropical cyclone remained weak as it moved slowly northward, but gradually intensified into a Category 1 hurricane on the modern day Saffir–Simpson hurricane wind scale east of Nicaragua at 18:00 UTC on November 13. A ship at or near the storm's center during that time documented a pressure of 992 mbar (hPa; 29.30 inHg).

Slow intensification took place after classification as a hurricane, though after recurving northeastward, the storm began to quicken in strengthening. On November 18, the cyclone reached its peak intensity with maximum sustained winds of 115 mph (185 km/h), making it equivalent to a Category 3 hurricane. Initially, it was believed that the storm became a Category 4 hurricane, but this was determined to be too strong of an intensity. A relatively small tropical cyclone, the hurricane made landfall along the western coast of Jamaica late on November 18. At the time of landfall, a pressure of 965 mbar (hPa; 28.50 inHg) at South Negril Point — the lowest barometric pressure documented anywhere during the storm's existence. Despite only briefly moving inland, the hurricane quickly weakened after landfall and continued to do so upon reentry into the Caribbean Sea. On November 20, the hurricane weakened to a tropical storm south of Cuba. Due to ambiguous surface observations in the area at the time, the storm was originally believed to have progressed northwards through the Atlantic before clipping Newfoundland; another scenario indicating that the storm made landfall in New York also seemed possible. However, reanalysis concluded that the system instead tracked westward across the Caribbean, slowly weakening before dissipating on November 22 north of Honduras.
