Thanks for the update. No, I wish no harm on anyone. It's my wish that Gustav peters out in the Gulf, but it doesn't look like that will happen.
The BYU worst case scenario was (and maybe still is) for the eye to come ashore to the right of the city. That way, Lake Pontchartrain to the north fills up and overtops the levees. Much like happened with Katrina.
From what I have seen its rare that a cat 5 storm keeps that level for a long, long time, just very rare. Seems the conditions have to be almost perfect to achieve that level and maintain it.
I think the rain possibilities will all be controlled by forward speed.
