There really is nothing showing New Orleans getting hit DIRECTLY by this hurricane. She will be impacted though. I am not sure why some people keep saying N.O. is going to be hit head on. Doesn't look that way.
Major delays at airport in Houston. Not enough screeners.
I'm certainly not thinking a direct hit at New Orleans -- yet. But, it sure is possible. The tracks are constantly shifting eastward and this monster is much closer to the Louisiana Gulf Coast than it is to Texas. In any event, as the cone, graphs, whatever keep shifting eastward, New Orleans will get decidedly much more than it can handle (and that isn't much).
