Hurricane Wilma, of October 2005, was the most intense tropical cyclone ever recorded in the Atlantic basin. Wilma was the twenty-second storm (including the subtropical storm discovered in reanalysis), thirteenth hurricane, sixth major hurricane, and fourth Category 5 hurricane of the record-breaking 2005 season. A tropical depression formed in the Caribbean Sea near Jamaica on October 15, and intensified into a tropical storm two days later, which was named Wilma. After heading westward as a tropical depression, Wilma turned abruptly southward after becoming a tropical storm. Wilma continued intensifying, and eventually became a hurricane on October 18. Shortly thereafter, extreme intensification occurred, and in only 24 hours, Wilma became a Category 5 hurricane with winds of 185 mph (295 km/h).

Intensity slowly leveled off after becoming a Category 5 hurricane, and winds had decreased to 150 mph (240 km/h) before reaching the Yucatán Peninsula on October 20 and 21. After crossing the Yucatán Peninsula, Wilma emerged into the Gulf of Mexico as a Category 2 hurricane. As Wilma began accelerating to the northeast, gradual re-intensification occurred, and the hurricane became a Category 3 hurricane on October 24. Shortly thereafter, Wilma made landfall in Cape Romano, Florida with winds of 120 mph (190 km/h). As Wilma was crossing Florida, it had briefly weakened back to a Category 2 hurricane, but again re-intensified as it reached the Atlantic Ocean. The hurricane intensified into a Category 3 hurricane for the final occasion, but Wilma dropped below that intensity while accelerating northeastward. By October 26, Wilma transitioned into an extratropical cyclone southeast of Nova Scotia.
