As a Florida native, being thru each Hurricane in the last 44 years, I will be out immediately following the storm. If you use common sense you should avoid serious issue. Hurricane Andrew, a Cat 5, caused about 65 deaths.......most of which was south florida, which was about 40 and easily attributable from stupid things such as trying to be outside (homeless) during the storm. That puts the odds at around .000005
The roads will be hell, every public area that can be fenced/locked will be, no one would advise you to be out.........but I will be going, as I have done each time. I hate these storms, but if its going to come, and do its thing, I am at least going to capture the silver lining.
