Effects of Hurricane Dennis in Florida

The effects of Hurricane Dennis in Florida included 14 deaths and $1.5 billion (2005 US$) in damage. The tropical wave that became Hurricane Dennis formed on June 29, 2005, and proceeded westward across the Atlantic Ocean. It became a tropical depression on July 4, a tropical storm on July 5, and a hurricane on July 7. Dennis rapidly intensified to attain Category 4 status on the Saffir-Simpson Hurricane Scale, and made landfall in Cuba where it weakened to Category 1 status, before re-emerging in the Gulf of Mexico and re–intensifying. The storm made landfall as a Category 3 hurricane on Santa Rosa Island on July 10.

As Dennis was impacting Cuba, the outer rainbands affected the Florida Keys causing moderate wind gusts peaking at 87 mph (140 km/h) on Sombrero Key. In central Florida, Dennis produced numerous tornadoes, one severely damaging a house. In Punta Gorda, three people were found dead in a car submerged in a ditch flooded by heavy rain. Dennis made landfall in the Florida Panhandle, causing moderate damage, although not as severe as previously predicted. Wind gusts peaked at 121 mph (195 km/h), and maximum rainfall reached 7.08 inches (180 mm). Storm surge of −-15 ft (−0.91 m) inundated parts of St. Marks and nearby locations. During the height of the storm, approximately 236,000 customers in the Florida Panhandle were without electric power.
