The 1924 Cuba hurricane is the earliest officially classified Category 5 Atlantic hurricane on the Saffir–Simpson scale. It formed on October 14 in the western Caribbean, slowly organizing as it tracked northwestward. By October 16, it attained hurricane status to the east of the Yucatán Peninsula, and subsequently executed a small counterclockwise loop. On October 18, the hurricane began undergoing rapid deepening, and the next day it reached an estimated peak intensity of 165 miles per hour (270 kilometres per hour). Shortly thereafter, it struck extreme western Cuba at peak intensity, becoming the strongest hurricane on record to hit the country. Later the hurricane weakened greatly, striking southwestern Florida with winds of 90 mph (150 km/h) in a sparsely populated region. While crossing the state it weakened to tropical storm status, and after accelerating east-northeastward, it was absorbed by a cold front on October 23 south of Bermuda. Across the western Caribbean Sea, the developing storm produced heavy rainfall and increased winds. Strong winds in western Cuba caused severe damage, with two small towns nearly destroyed. About 90 people were killed in the country, all in Pinar del Río Province. Later, the hurricane brought heavy rainfall to southern Florida, which caused flooding and crop damage. Damage was light in the state, and there were no casualties. ==Meteorological history== On October 14, a tropical depression was first observed over the western Caribbean Sea, just off the eastern Honduras coast. It was a large and weak tropical cyclone, moving slowly northwestward and gradually intensifying. On October 15, it is estimated the depression attained tropical storm status, and its strengthening became more steady. The next day, the storm reached hurricane status about 130 mi (215 km) southeast of Cozumel, Quintana Roo. Around that time, it began to execute a small counterclockwise loop off the east coast of the Yucatán Peninsula. By October 18 the hurricane completed the loop, during which its winds increased to 115 mph (185 km/h); this is the equivalence of a major hurricane, or a Category 3 on the Saffir–Simpson Hurricane Scale. The estimation of its strength at this point was based on subsequent analysis of peripheral recordings of atmospheric pressure and maximum sustained winds by ships and land stations. Beginning late on October 18 as it tracked north-northeastward toward Cuba, the hurricane underwent rapid deepening, evidenced by a ship wind report of 120 mph (193 km/h). This wind report was initially thought to be the peak intensity of the cyclone; however, subsequent research confirmed further deepening, based on very low pressures recorded across the region. A ship in the radius of maximum winds reported a reading of 922 mbar; the barometer on the ship was found to be 5 mbar too high, resulting in a pressure of 917 mbar.〔 Additionally, a station on land reported a pressure of 932 mbar (27.52 inHg). Based on the readings, the Hurricane Research Division estimated the hurricane attained a minimum central pressure of 910 mbar very near the western coast of Cuba; this suggested peak winds of 165 mph (270 km/h). Late on October 19, the hurricane made landfall in extreme western Cuba in Pinar del Río Province.〔 José Carlos Millás, director of the National Observatory at Havana, believed that "this hurricane () one of the most severe ever experienced in our latitudes."〔 After exiting Cuba into the Gulf of Mexico, the hurricane weakened greatly. On October 20 it passed a short distance west of Key West, Florida, and very early on October 21 the hurricane moved over Marco Island with winds of 90 mph (150 km/h). The cyclone weakened further as it turned eastward through the state, deteriorating to tropical storm status as it passed near or over Miami. It accelerated east-northeastward, moving over the Abaco Islands in The Bahamas. Gradually weakening, the storm interacted with an approaching cold front; late on October 23 it transitioned into an extratropical cyclone, and shortly thereafter it was absorbed by the front.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1924 Cuba hurricane」の詳細全文を読む スポンサード リンク
