http://www.nd.edu/~adcirc/movies/pam1.swf Takes a while to load cuz its flash, but it shows a moving map of the water direction and water levels as a theoretical hurricane moves through the barataria area up east of new orleans.. exact same path that Katrina is following....
Notice to the west the water is actually drawn out away from the land before the storm comes in and pushes it back up..
it looks like this storm actually goes west of no while katrina looks like it will end up making landfall east of no. atleast let's cross out fingers it does.
