New Orleans isn’t out of the woods yet by any means, but it looks like the strange course change that Katrina made shortly before making landfall prevented the predicted worst case scenarios from happening. Here are a few different links with more up to date information:
The SuperDome roof didn’t hold up too well as Wonkin’ in Detroit shows.
New Orleans Metroblogging has the best coverage of damage and flooding in the various parishes in and around New Orleans.
Josh Britton has also been doing a ton of posting on Hurricane Katrina (although he just lost power).
And of course brendanloy.com still has a ton of good information as well.
