The 1926 Louisiana hurricane caused widespread devastation to the United States Gulf Coast, particularly in Louisiana. The third tropical cyclone and hurricane of the 1926 Atlantic hurricane season, it formed from a broad area of low pressure in the central Caribbean Sea on August 20. Moving to the northwest, the storm slowly intensified, reaching tropical storm strength on August 21 and subsequently attaining hurricane strength after passing through the Yucatán Channel. The hurricane steadily intensified as it recurved northwards in the Gulf of Mexico, before reaching peak intensity just prior to landfall near Houma, Louisiana on August 25 with winds of . After moving inland, the tropical cyclone moved to the west and quickly weakened, before dissipating on August 27. The hurricane's strong storm surge at landfall caused extensive damage to coastal regions, especially lighthouses. Strong winds caused severe infrastructural and crop damage, destroying homes and disrupting communications. Heavy rainfall, peaking at in Donaldsonville, Louisiana, also helped to damage crops. Widespread power outages also occurred in areas along the Gulf Coast. 25 deaths were reported as a result of the hurricane, with damages estimates totaling $6 million. ==Meteorological history== A tropical depression first formed on August 20 in the central Caribbean Sea from a broad area of low pressure, based on weather reports from weather stations and ships in the vicinity. Moving steadily to the west-northwest towards the western Caribbean, the disturbance slowly intensified, attaining tropical storm strength by 1200 UTC the next day. Prior to the Atlantic hurricane reanalysis project, however, the system was analyzed to be an open trough up until August 22.〔 The tropical storm began to move more towards the west in the Gulf of Mexico after clipping the Guanahacabibes Peninsula—the westernmost region of Cuba—late on August 22. Once in the Gulf of Mexico on August 22, the tropical storm continued to intensify, reaching hurricane strength early the next day north of the Yucatán Peninsula. A ship in the hurricane's vicinity reported a barometric pressure of 994 mbar (hPa; 29.36 inHg), and other ships also reported similarly low pressures.〔 Beginning on August 24, the system began to curve northwards towards the Louisiana coast in response to a nearby cold front. The hurricane continued to intensify as it moved northwards, reaching Category 2 hurricane intensity the same day and subsequently the equivalent of a Category 3 hurricane on August 25. A ship reported an eye associated with the system, observing 100 mph (160 km/h) winds with a pressure of 959 mbar (hPa; 28.32 inHg) at 2100 UTC that day.〔 The major hurricane intensified up until making landfall near Houma, Louisiana at 2300 UTC late on August 25, with winds estimated at 115 mph (185 km/h) and an estimated minimum barometric pressure of 955 mbar (hPa; 28.20 inHg), based on a pressure report of 959 mbar (hPa; 28.32 inHg) in Houma. Maximum sustained winds extended 23 mi (37 km) from the hurricane's center. Once over land, however, the hurricane rapidly weakened. By 1200 UTC on August 26, the system had already degenerated to a tropical storm, while still located over Louisiana near Baton Rouge. The next day, the storm weakened further to tropical depression strength as it moved towards the west, before degenerating into an open trough of low pressure near Hillsboro, Texas by 1800 UTC on August 27.〔 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「1926 Louisiana hurricane」の詳細全文を読む スポンサード リンク
