Orleans Parish is under mandatory evacuation. It includes the city within the flood wall and Algiers Point on the West Bank. A few other parishes are closed--and the ones adjacent to NOLA--I am sure are being rescued and taken to the interstate or the dome.
ETA: I have followed the story with interest as Algiers Point is my old neighborhood....
