man that sounds very very bad. Ketrina might miss NO, thought looks to still have a strong west component, NO might still dodge this bullet.
Not really. Even if Gulfport, MS gets the worst of it, there will still be at least CAT 4 winds blowing south on the west side of Katrina - driving Lake Ponchartrain right into the city. The Superdome might not cave in from 200 mph winds, but the flooding will still amount to a worst-case scenario.
