Governor Cuomo just declared a state of emergency for New York State in the last half-hour or so. This is good – New York City and the Hudson River are going to be in the northeast quadrant of the storm (lots of surge, and it will travel up the Hudson).
Oddly enough, if the current GFS model track verifies with a landfall near or on Long Island, that actually would be better for New York City. The strongest winds of the storm wouldn’t be blowing the Atlantic Ocean and Long Island Sound into town and up the rivers.
But that scenario is looking less and likely right now.
