Mourning in New Orleans?

New Orleans may very well get wiped off the map tomorrow. If I was a prophet I'd predict it but I'm not and so I won't. All I know is that I read something very similar to this series about a year ago (Read all of it, pretty scary and it was all known in advance) .

Researcher Jay Combe has reached a troubling conclusion. He's told his supervisors at the Army Corps of Engineers that if The Hurricane hits New Orleans, most of the buildings in the city would probably be destroyed. If the water didn't demolish them, the hurricane's horrific winds would. And Combe says that raises a question: How many people would die?
Some researchers say 40,000. Some say 20,000. This Army Corps researcher says those figures are probably too low.
Combe worries, "I think of a terrible disaster. I think of 100,000."
Do you dream sometimes about a hurricane?
"It's strange you should ask that," answers Combe. "I had a dream the other night about flooding, and it's unusual because I don't usually have bad dreams. I can't really remember the dream except that water was coming down a slope. I don't remember much of it, fortunately. I don't want to remember."
