Hurricane Irma was an extremely powerful and devastating tropical cyclone that caused extensive damage and loss of life across the Antilles and Eastern United States in September 2017. Irma was the first Category 5 hurricane to strike the Leeward Islands on record, though it was followed by Hurricane Maria, which struck the region at Category 5 intensity as well two weeks later. At the time, Irma was considered the most powerful hurricane on record in the open Atlantic region, outside of the Caribbean Sea and Gulf of Mexico, until it was surpassed by Hurricane Dorian two years later. It was also the third-strongest Atlantic hurricane at landfall ever recorded, just behind the 1935 Labor Day Hurricane and Dorian. Irma was the ninth named storm, fourth hurricane, second major hurricane, and first Category 5 hurricane of the extremely active 2017 Atlantic hurricane season.
