Another Katrina casualty?

LSU (Geaux Tigers!) has a hurricane expert on staff who PBS says warned officials of the potential for disaster in a Katrina-like event:

"A slow-moving Category 3 hurricane or larger will flood the city. There will be between 17 and 20 feet of standing water, and New Orleans as we now know it will no longer exist."

The Times-Picayune reports that he has been fired and the resulting letters are interesting.
