Hurricane Wilma formed on October 17 in the western Caribbean southwest of Jamaica and rapidly strengthened. On October 19 it became the strongest tropical cyclone on record in the Atlantic basin, with 185 mph (295 km/h) winds and a central pressure of 882 millibars (26.0 inHg). It then moved slowly and struck Quintana Roo on October 22 as a Category 4 hurricane, causing very heavy damage to Cancún and Cozumel.
