I don't believe the superdome can withstand the expected wind pressure. I think the sides and the entire structure will go.
I wouldn't want to be in the Superdome during this storm.
I agree. That's what happened with Hurricane Camille in 1969 -- the coastline got wiped out. The buildings could not handle 200 mph sustained winds (in 1969).
A taller and larger structure (such as the Superdome) would probably be even more vulnerable.
