The head of the Federal Emergency Management Agency calls the destruction on the Mississippi Gulf Coast and in New Orleans "a very sobering scene."
FEMA Director Michael Brown says patience is an extreme priority right now and authorities aren't going to allow people to return to flooded neighborhoods.
Brown was interviewed this morning by NBC's "Today" show.
He said all low-lying area in Biloxi, Gulfport, and New Orleans are just devastated.
Brown says President Bush has declared virtually all of Louisiana, Mississippi, and Alabama as disaster areas.
