Ed, best of luck to you and all Florida/GA/SC/NC members who will be affected by Hurricane Irma. If you are having to get out of hunker down, my prayers are with you, as they still are for all those still affected by Harvey.
Now my question; I'm seeing predictions of storm surge numbers up to and above 12 feet. I know these will affect areas like Ft. Myers, where my in-laws recently sold their home, but how far inland can these surges be expected? My concern is for an area like Lake Okeechobee. I understand it is several miles inland but what might be the damage if it did sustain a surge of salt water?
