It's currently looking pretty unlikely that Florence will impact Florida at all, but still too early to tell anything for sure. Weather models for Florence right now aren't giving anything more useful than "there will be a storm, at a place" more than about 5 days out (when it could make landfall).
Of more concern to Florida is the system that's likely to follow (this is the red X on the
NHC map). Again, still too early to tell about any potential US impacts, but this one's looking likely to at least make its way into the Caribbean and will be worth keeping an eye on if you're in Florida towards the end of next week.
