Do you want a new fifth wheel?
These storms are hundreds of miles wide and Florence is looking to be category 3 or 4.
Don't **** around. The areas it is going to hit aren't built like they are in Florida. There is going to be massive damage.
If you want a new fifth wheel go ahead and leave it. Odds are probably decent even 60 miles in you'll see category 1 sustained at minimum, probably more and winds with gusts well into 2 and 3.
Sure it might make it. Might not. If I wanted to keep it, I wouldn't leave it.
