The 1933 Treasure Coast hurricane was the second-most intense tropical cyclone to strike the United States during the active 1933 Atlantic hurricane season. The eleventh tropical storm, fifth hurricane, and the third major hurricane of the season, it formed east-northeast of the Leeward Islands on August 31. The tropical storm moved rapidly west-northwestward, steadily intensifying to a hurricane. It acquired peak winds of and passed over portions of the Bahamas on September 3, including Eleuthera and Harbour Island, causing severe damage to crops, buildings, and infrastructure. Winds over affected many islands in its path, especially those that encountered its center, and many wharves were ruined. Subsequently, it weakened and made landfall at Jupiter, Florida, early on September 4 with winds of . The hurricane moved across the state, passing near Tampa before moving into Georgia and dissipating. In Florida, the strong winds of the cyclone blew buildings off their foundations, and numerous trees were prostrated in citrus groves. The Treasure Coast region received the most extensive destruction, and Stuart, Jupiter, and Fort Pierce were heavily damaged. Inland, the cyclone weakened rapidly but produced prodigious amounts of rain, causing a dam to collapse near Tampa. The storm caused $3 million in damage (1933 USD) after damaging or destroying 6,848 homes. Unusually, the storm hit Florida less than 24 hours before another major hurricane bearing winds struck South Texas; never have two major cyclones hit the United States in such close succession. ==Meteorological history== The origins of the hurricane were from a tropical wave that possibly spawned a tropical depression on August 27, although there was minimal data over the next few days as it tracked to the west-northwest. On August 31, a nearby ship reported gale force winds, which indicated that a tropical storm had developed to the east-northeast of the Lesser Antilles. Based on continuity, it is estimated the storm attained hurricane status later that day. Moving quickly to the west-northwest, the storm passed north of the Lesser Antilles and Puerto Rico. Early on September 2, a ship called the ''Gulfwing'' reported a barometric pressure of , which confirmed that the storm attained hurricane status. After passing north of the Turks and Caicos islands, the hurricane struck Eleuthera and Harbour Island in the Bahamas on September 3, the latter at 1100 UTC. A station on the latter island reported a pressure of during the 30 minute passage of the eye.〔 Based on the pressure and the small size of the storm, it is estimated the hurricane struck Harbour Island with peak winds of , making it the equivalent of a modern Category 4 hurricane on the Saffir-Simpson scale. Interpolation suggested that the storm reached major hurricane status, or Category 3 status, on September 2.〔 The hurricane initially followed the course of another hurricane that passed through the area in late August, which ultimately struck Cuba and Texas. This hurricane instead maintained a general west-northwest track.〔 After moving through the northern Bahamas, the hurricane weakened slightly before making landfall at Jupiter, Florida, at 0500 UTC on September 4. A station there reported a pressure of during a 40 minute period of the eye's passage; this suggested a landfall strength of . At the time, the radius of maximum winds was 15 mi (24 km), which was smaller than average. After landfall, the hurricane weakened rapidly while crossing the state. It briefly emerged into the Gulf of Mexico as a tropical storm early on September 5. A few hours later while continuing to the northwest, it made another landfall near Rosewood—a ghost town in Levy County, east of Cedar Key—with winds of about . Turning to the north, the storm slowly weakened as it crossed into Georgia, dissipating on September 7 near Augusta.〔 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「1933 Treasure Coast hurricane」の詳細全文を読む スポンサード リンク
