Speaking of New Orleans, here is the NOAA prediction for the most likely path for Hurricane Gustav (actually, it is Tropical Storm Gustav right now, but it should strengthen and become a hurricane again soon).
It is unlikely that Gustav will be a category 4 or 5 hurricane like Katrina, but it could still do a lot of damage wherever it hits. This map is called a 5-day cone, with the stippled area from south Texas to the Florida panhandle indicating the possible landfall area, and the black dashed line being the most probable path.
