Foley should be OK from storm surge. In Camille, the storm surge (70 ft waves) took out everything within 3 to 4 miles of the coast. That's the best I recall as a teen at the time.
Foley is more like 10 or 15 miles in. But it would be hit hard. There's nothing but flat, barren land between Foley and the coast...nothing to slow down the storm.
Thinking of you....and will pray hard that you and yours stay safe...and that Fl sends you some left over bottled water.
Can you screw the plywood on over your windows? How close to the coast are you? Prayers your way.
