It will probably be higher than that rather than lower. Could be wrong, but sounds like Mississippi is a horror. New Orleans people just didn't evacuate when they were supposed to. The worst is past, but we haven't discovered it yet.
We had that report about Gulfport from a FReeper the other evening saying there were numerous bodies in trees when the waters receded. Also a report of many NG and refrigerated trucks going to Mississippi for body retrieval. They are now announcing just 150 dead in that state, but that number is grossly underreported.
