I agree, keep the people of the city in your prayers.. even the damn fool people who think they are going to ride it out.
The thing is vicious. Just looking at the satellite pictures you can TELL its vicious. I'm kind of into weather myself, and honestly, that thing is about the most perfectly formed hurricane I've ever seen. The eye is perfectly round, and completely clear. In an evil and mother nature is a crazy ass bitch kind of way, its almost beautiful.
If you are in New Orleans, and haven't left yet, get out NOW. As I write this, it aint too late. I hope the city will just experience some flooding but I'm afraid it may be a lot worse. Here is what one meteorologist wrote on his blog:
"I put the odds of New Orleans getting its levees breached and the city submerged at about 70%. This scenario, which has been discussed extensively in literature I have read, could result in a death toll in the thousands, since many people will be unable or unwilling to get out of the city.
I recommend that if you are trapped in New Orleans tomorrow, that you wear a life jacket and a helmet if you have them. High rise buildings may offer good refuge, but Katrina has the potential to knock down a high-rise building. A 25 foot storm surge and 30 - 40 foot high battering waves on top of that may be able to bring down a steel-reinforced high rise building.
I don't believe a high rise building taller than six stories has ever been brought down by a hurricane, so this may not happen Monday, either. We are definitely in unknown waters with Katrina."
In short all bets are off.
