1912 Jamaica hurricane
The 1912 Jamaica hurricane was a slow-moving tropical cyclone that meandered about the island of Jamaica, causing torrential rainfall and severe flooding in November 1912. The strongest hurricane in the Atlantic that year, the cyclone formed in the southwestern Caribbean Sea on November 11. Traveling slowly northward, the storm reached hurricane status on November 13, and slowly intensified before reaching its peak intensity as a Category 3 hurricane-equivalent on November 18 when it made landfall on Jamaica before weakening. After landfall, the tropical cyclone curved westward and dissipated north of Honduras on November 22.
==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 north of Panama at 06:00 UTC that day. Lowering 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 to reach hurricane intensity 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 towards the northeast 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 modern day Category 3 hurricane. Initially, it was believed that the storm reached Category 4 intensity, 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 in Jamaica—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 it dissipated on November 22 north of Honduras.
