METAR KMSY 282053Z 06016G23KT 7SM BKN038 BKN047 32/24 A2961
Translation: At 2053Z (4:53 pm EDT), Louis Armstrong International had winds out of 060 degrees (ENE) at 16 knots gusting 23, visibility 7 miles, ceiling broken 3800 feet, broken 2700 feet, temperature 32C, dewpoint 24C, barometric pressure 29.61. That's flyable...or it was as of an hour ago. The window's basically closed, because in a couple hours, it *won't* be flyable.

That's kind of my point - it's too late to try aerial evacuation.
However, evacuation by rail should still be a viable option. Load up the boxcars and flatcars, chain locomotives at the front and rear and firewall the throttles. Should get out pretty quick - people weigh a lot less than what those things usually haul.
