You mentioned JFK Airport yesterday. Can you provide more details about that? I found a source indicating elevation of 13ft there. What events are you expecting upon storm arrival?
LaGuardia is actually more vulnerable than JFK, as it turns out.
One problem is that it will hit New York PRECISELY at high tide, which is 5 feet tacked on to the surge.
LaGuardia is under 3 feet of water in a “standard” Category 1; thats without a high tide, and doesn’t take into account the enormous size and slow movement of Irene.
