Are you crazy ? Have you heard of hurricanes ? If one starts building in the carribean, you'll go days wondering if you should get out. By the time they hurricane trackers say "yes, it will hit Florida", it's too late. Half the population will be on I-95 heading North. But you know what ? It won't just take hours to reach the state border, it will take days. Even then it doesn't matter since you'll still be on the coast. Florida is easy target for every tropical storm.
Here's something else to know: years ago there would coastal flooding once or twice a year from extraordinary high tides. This now happens 30-40 times a year because the rise in sea level caused by arctic ice melt and ocean warming.
The ocean warming means an increase in the number and severity of tropical storms/hurricanes.
Florida is a bad place to consider for a residence.
Look at the videos from this years hurricanes but especially at Hurricane Maria and what happened in Puerto Rico. Hurricane Maria in P.R. is a preview of what will happen increasingly in Florida and the Carolinas.
