I too didn't understand what all the fuss was about. The weather guy (central alabama) explained it better. He said the Mississippi River is already very high. This storm is expected to push a lot of water back up the river. The dams/levee part protecting New Orleans is at 20'. This is expected to push that up to 19'. Not a good scenario for our neighbors over there. I don't know much about the levee's or such but it bears watching.
