The worst case scenario has never actually happened in New Orleans -- yet -- despite the fact that we've been recording history in the area since the French settled in the area three hundred years ago.
I hypothesize that all the marshland/swampland acts pretty much like dry land in breaking up the storms as they get close. So a storm would have to remain over water to really inundate the area -- come in through the Rigolets and the lakes.
If this storm jogs to the west after coming a bit more north, that would be bad for the Parish of Orleans.
But Plaquemines and Slidell are going to be flooded.
thats what I will take away from this if NO is spared - the models that predict this armadgeddon scenario for NO, in reailty, can't occur, or if they can, the odds are fantastic.
it would be a hoot if the best forecaster for this storm, is "Sam", the guy that Shep Smith interviewed in the Daquiri Bar on bourbon street.
