PA, this is truly unprecedented. My folks are in health, under a dry roof, have transportation and credit cards, and are still overwhelmed.
Because the media are focusing on stupid areas like Bourbon Street, they have no idea if their home still has a roof, is underwater, or whatever.
More than one levee has been breached, which is why the aerial shots you see on TV show so much water everywhere. They are moving critically ill patients to the Superdome, which already has overflowing, fetid toilets, no air conditioning, and is already crowded with people, But the water is rising in at least 3 hospitals and the patients cannot be taken care of there anymore.
It's even worse over in Mississippi in Gulfport, Biloxi, and the little towns that surround them, altho I hear at least aid stations are available over there.
Plaquemines Parish, southeast of the New Orleans area, has suffered terribly as well, and they can't even get helicopters in to film the damage. At least 25% of that parish (i.e., county) is just GONE.
