Looks like New Orleans will be going through the rinse cycle.
That might actually be good for the city. A new flood would dilute the toxic sludge on the city streets. Mother nature likes cleaning up after herself.
Looking at all the satellite photos of storms: It is amazing how storms manage to fill the whole gulf. I guess it is actually the gulf that makes the storm. I am now wondering about the extent to which the whole geology of the United States was defined by a continuous stream of hurricanes. Just imagine millions of storms the size of Rita and Katrina battering the coast through geologic time. These storms could be a prime factor in the distintive shape of the Gulf of Mexico.
