I would not be surprised to see some weird and "unplanned for" damage, possibly causing some serious issues. For example, during Hurricane Katrina in Biloxi, casino barges and ships were carried inland and plowed into buildings. I have not been in that region for many years, but I do recall some major high rise buildings set right on the beach. Hopefully, they completely evacuated those buildings. My understanding is that some hotels could not be evacuated so they are requiring guests to stay in their rooms, or maybe even more disturbing, moved them into the mountains. There could easily be 20 inches+ of rain hitting the mountains creating insane floods and mudslides.
