Obviously, we're not in a death bowl like NOLA, but the sights from Biloxi and Gulfport are pretty damn scary. A 25ft surge that comes in and out would likely scrub clean any of the areas on the pic above that are blue.
I'm in Largo, but we'd be stuck if we tried to drive north because all the dozens of little bridges on 19, alt19 and all the other N/S roads would be down or damaged even after the water retreats. Welcome to Pinellas Island.
BTW- I can't figure out why they didn't shade out all the barrier islands. They sure as hell are the first to go. We'd have a lot more passes to the Gulf after a "Katrina".
