Grew up people taking about Camille. Cat 5 that hit MS in the middle of the night. Read a while back about a group that was in an apartment building and when the surge hit they started moving up the floors. Several of them drowned even with muliple floors to go up. I remember going to Biloxi in the 70s and some pretty large boats being inland from the coast. Behind MS and LA the biggest damage was Virginia where it washed out a number of bridges due to the rain.
I've never run from a hurricane having grown up in LA and most of my adult life in TX. But if you live right on the coast I don't see how people don't leave to avoid the surge. The wind and lack of power wouldn't bother me. The surge would. Even after Katrina the morning after it hit people were taking videos in the quarter talking about how it wasn't a big deal. Until it was due to the levee breaks. MS got it much worse during Katrina for that season, the storm surge.
I imagine there's a lot of "things are going okay" in some of those storms. Until a house down the road goes floating by.
