I have the Hurricane Evacuation Map from the NYC office of Emergency Management hanging right here on the wall behind my desk.

Get it here in the language of your choice:

It's a really, really interesting map, as it puts places like JFK and LGA airports UNDER WATER in a Category 2 or better hurricane. Think about that for a moment. That's a scenario that has GLOBAL implications.

South Brooklyn is in a bad way no matter what.
