It is way too early to start worrying about N.O. any more than anywhere in the Gulf. If you want to make God laugh; tell him when, where, or how strong a hurricane will be next week...
That doesn't mean that everyone on the Gulf coast shouldn't have already packed plenty of water, batteries, assessed their shutters etc. They should also have in place an exit strategy if
the storm comes their way. I would hope the incompetents that run N.O. at the very least have a bus plan to get the people out who don't have cars. N.O. is uniquely vulnerable as the city is actually below sea level... and surrounded by water.
(People really shouldn't live there. It’s kinda like pitching camp at the base of an active volcano.)
