I did hear on two different radio stations that only 20% of the residents in the Keys left the island. They showed some footage of people partying at various bars in Key West. They just mentioned about an hour ago that they are "no longer partying here."
Steve Jerve just went through when and what affects we will feel in each county.
Since I live in Polk, here's what he said:

9AM - 2PM :
Squalls/Tornados
Winds 30-50mph === possibility of being sustained winds
Gust to 60 possible.

So, I think maybe those of us in Polk county may be able to get some sleep tonight instead of waiting another 7 hours!
