I was a trucker.
I helped with the aftermath of Katrina and half a dozen other hurricanes.
After what I saw during those years I'd be high tailing it for the high ground way ahead of any mandatory evacuation odur.

oh..fun fact.
I was in dallas when they had a F5 tornado rip thru. I saw a video of it tossing semitrucks around like kids playtoys.

That was a MONSTER F5 (windspeeds of over 200 mph)
Irma has windspeeds of over 200mph.

Irma is a tornado the size of Ohio...
Just so ya know.
