In a press conference today, New Orleans Mayor Ray Nagin said six houses had collapsed – five within one hour, and that 28 others are in danger of collapsing today, presumably as a result of Hurricane Gustav. He urged hurricane survivors returning home to avoid any buildings that appear dangerous.

Hurricane Katrina began a blight assault on the city, and many homes and other buildings – as many as 400 – have been slated for demolition, with many others already demolished as a result.

The homes that fell down today were all unoccupied, and there were no injuries reported.
