Hurricane Irma and Hurricane Wilma we're which category of hurricane at their strongest?
Hurricane Irma Hurricane Irma was an extremely powerful and catastrophic Cape Verde-type hurricane, the strongest observed in the Atlantic since Wilma in 2005 in terms of maximum sustained winds. It was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Hurricane Maria only two weeks later. It was also the most intense Atlantic hurricane to strike the United States since Katrina in 2005, and the first major hurricane to make landfall in Florida since Wilma in 2005. The ninth named storm, fourth hurricane, and second major hurricane of the 2017 Atlantic hurricane season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in parts of the northeastern Caribbean and the Florida Keys.
List of United States hurricanes 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 293 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.
