Look at the hurricane Ike advisories in 2007 for Galveston prior to landfall. The phrase "certain death" was in it. Ike was a cat 2 hurricane with light winds, but the large size brought deadly flooding. This storm compare with Ike more than Katrina. They were wrong though, practically everyone on the bolivar peninsula that stayed, died. There were 2 survivors. I guess death wasn't certain. But they had a hell of a ride. One guy ended up travelling 17 miles over land (with the storm surge) by travelling with houses, boats, cars and trees and managing to not get fatally impaled by the drift. The other guy luckboxed it in a kayak.
