Hurricane Michael was a very powerful and destructive tropical cyclone that became the first Category 5 hurricane to strike the contiguous United States since Andrew in 1992. In addition, it was the third-most intense Atlantic hurricane to make landfall in the contiguous United States in terms of pressure, behind the 1935 Labor Day hurricane and Hurricane Camille in 1969. It was the first Category 5 hurricane on record to impact the Florida Panhandle, the fourth-strongest landfalling hurricane in the contiguous United States, in terms of wind speed, and the most intense hurricane on record to strike the United States in the month of October.
The thirteenth named storm, seventh hurricane, and second major hurricane of the 2018 Atlantic hurricane season, Michael originated from a broad low-pressure area that formed in the southwestern Caribbean Sea on October 1. The disturbance became a tropical depression on October 7, after nearly a week of slow development. By the next day, Michael had intensified into a hurricane near the western tip of Cuba, as it moved northward. The hurricane rapidly intensified in the Gulf of Mexico, reaching major hurricane status on October 9.
