The National Weather Service has issued a "hazardous weather outlook" for New York City, but it doesn't sound like snow will be the big issue.
Don't expect any snow days in the NYC-area because of this :-(
The NWS predicts between 1 to 2 inches for the city, though the ever-fear mongering Weather Channel is predicting around 3 to 5 inches of snow. Expect some gross rain-snow mix either way on Wednesday evening, becoming snow overnight, as well as a lot of wind. Winds could occasionally gust over 40 mph.
Things will get terrible Thursday morning, so commuting might be awful. Worst of all, however, the wind will continue to ravage the already ailing beaches, as the winds and flooding will cause "significant erosion." Expect coastal flooding ... the worst since Hurricane Sandy.
Expect most of the flooding during high tide Wednesday afternoon as well as late Wednesday night.
