Katrina is scary. The photos from the news sites reminds me of the Day After Tomorrow. Here are photos from real people posted at flickr. Even scarier photos from newswires

Also, here are some evidence that Hurricanes will go from bad to worse in the upcoming years due to global warming.

An implication of these studies is that if the frequency of tropical cyclones remains the same over the coming century, a greenhouse-gas induced warming may lead to a gradually increasing risk in the occurrence of highly destructive category-5 storms.

I don't understand much of the science that goes behind weather and hurricane systems, but it looks bad. And will be not nice to know that the reason that Katrina is a category 5 hurricane is due to global warming.
