There was a "disaster expert" (I don't remember his actual title) on the news the other day saying that, in an event of this magnitude, 1/3 of the people remaining in the affected area will die, due to the initial impact (the storm), second impacts (the flooding), disease, starvation, and violence.

They thought about 2/3 of the 900,000 in the NO metro area got out, so that means 100,000 may still be the total.

I mean, we'll never know for sure. Yipes.
