IIRC, before the hurricane hit, people were told to bring food and water sufficient for 5 days.
Those in need of urgent medical attention are being (100's have been) moved out, and I picture the dome as a staging point for transportation to dry land and outside destinations.
It is mind boggling, the sudden relocation of a million people.
This also blows my mind about this entire tragedy. Not only do we probably have hundreds (at minimum) dead in coastal Mississippi, Alabama, and the areas south of New Orleans from the wind and storm surge. We're talking about the complete disruption of one of the larger cities in the United States. No housing, no infrastructure, no jobs. It's incomprehensible. The closest thing we've seen recently is the aftermath of Andrew, and while the total destruction of Homestead and south Dade County was bad, this may even be worse.
