1960:

"The most notable storm of the season was Hurricane Donna, which reached Category 5 status on the Saffir-Simpson Hurricane Scale and was the longest-lasting major hurricane in the history of the Atlantic basin. It was the worst storm to strike Florida in ten years, causing six direct deaths, and causing $387 million in damage ($2.4 billion in 2000 dollars).

Also, Ethel reached Category 5 strength very briefly before falling apart prior to landfall in Mississippi. This marks the first of only four seasons that two or more Category 5 hurricanes were officially recorded (the others being the 1961, 2005 and 2007 seasons); it remains the only season with two consecutive Category 5 hurricanes."

After Donna, Florence was a spring shower for Florida. ;}
