1931 Belize hurricane
The 1931 Belize hurricane was a devastating Category 4 tropical cyclone that struck British Honduras on 10 September 1931, killing an estimated 2,500 people. Although weaker than Hurricane Hattie of 1961, it remains the deadliest hurricane and natural disaster in British Honduras history. The hurricane was first detected as a tropical wave off the west coast of Africa on 29 August. Moving westward, the disturbance remained relatively weak till 6 September, when it was first classified as a tropical cyclone just west of the Windward Islands. The depression gradually intensified, reaching tropical storm intensity within the first six hours following tropical cyclogenesis. The cyclone intensified further to hurricane intensity by 8 September. Strengthening and organization remained gradual until the storm reached the Gulf of Honduras, by which time it began to rapidly intensify. The tropical cyclone quickly attained Category 4 hurricane intensity. The hurricane subsequently made landfall on Belize City on 10 September with maximum sustained winds of 135 mph (215 km/h) and a minimum barometric pressure of 952 mbar (hPa; 28.12 inHg). Moving across the Yucatán Peninsula, the tropical cyclone weakened, and continued to weaken when it moved across the Bay of Campeche. This track brought it to a second landfall north of Tampico, Mexico as a tropical storm on 13 September. Once inland, the storm quickly weakened, and dissipated later that day.
==Meteorological history==
The hurricane began as a tropical wave—a westbound low-pressure area—first observed southeast of Cape Verde on 29 August. Traversing the tropical Atlantic, the wave retained a minimum barometric pressure of about 1010 mbar (hPa; 29.83 inHg) and strengthened briefly the following day. By 1 September, however, the wave had become rather weak and indiscernible; it would remain as such for much of its early existence till 6 September, by which time it had moved past the Windward Islands. In this region the system became sufficiently organised to be classified as a tropical depression at 1800 UTC that same day, about north-north-west of Grenada. Some six hours after its inception the depression strengthened to a tropical storm over the eastern Caribbean Sea. Owing to a lack of ship observations, data on the storm were scarce in that region. The first ship to identify the storm clearly was the tanker ''Geo H. Jones'', which recorded strong winds in conjunction with rapidly decreasing barometric pressures late on 7 September.〔 As the storm remained north-north-westbound across the Caribbean, more ships were able to record data on the cyclone.〔
At 1800 UTC on September 8, the tropical storm attained hurricane intensity. Intensification remained gradual until the hurricane moved into the Gulf of Honduras by September 10, when the hurricane began to rapidly intensify. At 0000 UTC on September 10, the cyclone intensified into a Category 2 hurricane. The storm strengthened further before reaching its peak intensity with as a Category 4 hurricane with maximum sustained winds of 135 mph (215 km/h) at 1800 UTC. The strong hurricane made landfall on Belize City at the same intensity two hours later. A barometer in the city recorded a minimum pressure of 952 mbar (hPa; 28.12 mbar); this was the lowest barometric pressure measured in association with the storm.〔 The hurricane substantially weakened over the Yucatán Peninsula, and had weakened to tropical storm strength by the time it had entered the Bay of Campeche. Despite moving back over water, the tropical cyclone continued to weaken in the bay, and made its final landfall roughly 60–70 mi (95–110 km) north of Tampico, Mexico with winds of 40 mph (65 km/h) at around 0000 UTC on September 13.〔 Over the mountainous terrain of Mexico, the storm quickly weakened, and dissipated later on September 13.
