"It is going to result in havoc throughout the Downstate region – Long Island, New York City, the Hudson Valley," Gov. Kathy Hochul told 1010WINS. "We could have anywhere from three to five inches of rain, one inch an hour. And that may not sound like a lot, but if you are driving on a road and you start to see the water puddling on the street, you need to get off the road immediately."
