The list of United States hurricanes includes all tropical cyclones officially recorded to have produced sustained winds of greater than 74 mph (118 km/h) in the United States, which is the minimum threshold for hurricane intensity. The list, which is sorted by U.S. state, begins in 1851 with the start of the official Atlantic hurricane database (HURDAT), as provided by the National Oceanic and Atmospheric Administration's Hurricane Research Division; the data from 1951 to 1979 is subject to change, due to the lack of official wind speed estimates during the time period. Since 1851, a total of 289 North Atlantic hurricanes produced hurricane-force winds in 19 states along the Atlantic coast. Some of these storms may not have made a direct landfall (i.e. remained just offshore) while producing hurricane-force winds on land; some of them may have weakened to a tropical storm or became extratropical before landfall but produced hurricane conditions on land while still a hurricane and some of them made landfall in an adjacent state but produced hurricane conditions over multiple states. This list does not include storms that only produced tropical storm conditions on land in the United States. Additionally, three Pacific hurricanes struck Hawaii, and one Pacific tropical cyclone brought hurricane force winds to California. The tables list hurricanes by category on the Saffir-Simpson Hurricane Scale, based on winds that occurred in each state. ==Statistics== A total of 289 Atlantic tropical cyclones have produced hurricane-force winds in every state along the Atlantic Ocean and Gulf of Mexico, as well as Pennsylvania. Florida was affected by 116 hurricanes, which was more than any other state; Texas ranked second. Hurricane Donna affected a total of eight states—more than any other hurricane.〔 The earliest time in the year for a hurricane to strike the nation was June 9, which was set by Hurricane Alma in 1966. The earliest major hurricane to strike the nation occurred in 1934, when an unnamed tropical cyclone made landfall on June 16. The latest in the year for a hurricane to strike the nation was on November 24 with Hurricane Iwa in Hawaii; for the Atlantic basin the latest was on November 22, which was set by Hurricane Kate in 1985. The latest in the year for a major hurricane to strike the nation was from the 1921 Tampa Bay hurricane, which moved ashore on October 25.〔 The 1880s were the most active decade for the United States, with a total of 25 hurricanes affecting the nation. By contrast, the least active decade was the 1970s, with a total of only 12 hurricanes affecting the American coastline. A total of 32 seasons on record passed without an Atlantic hurricane affecting the country—the most recent of which was the 2013 season. Seven Atlantic hurricanes affected the country in the 1886 season, which was the year with the most United States hurricanes.〔 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「List of United States hurricanes」の詳細全文を読む スポンサード リンク
