Yahoo Maps w/Shaded Circles

Here are some graphics to give you a (very rough) idea of how flooding of the scale seen in New Orleans would impact other major American cities. (There were similar maps circulating a while ago about the effects of a dirty bomb, etc. Couldn't find any on Google.) Of course, these maps don't take into account topography or the effects of adjacent lakes and rivers for these other cities, but they are still interesting. Via Austin Mayor.
