HUDSON VALLEY, NY — Remembering the damage caused by rainstorms Henri and Ida in the past month, New York State readied equipment and resources as a storm front began moving through central and southern New York Thursday.

There's a small chance of thunderstorms or an isolated tornado. But with 1-2 inches of rain predicted, up to 3 or even more in some areas, most vulnerable are small streams and low-lying areas. Flood watches have been issued for Dutchess, Orange, Putnam, Rockland and Ulster counties.

The village of Mamaroneck warned residents already battered by Henri and Ida to take precautions, including moving cars from flood-prone streets.

Some storms may contain damaging winds, which could cause downed trees and power lines, New York officials warned. The state has also activated its swift water rescue teams, which were needed during Ida.

Remembering the flooding that closed I-87 in Rockland County, the New York State Thruway Authority is also prepping for the storm. The NYSTA encourages motorists to download its mobile app which provides direct access to live traffic cameras, real-time traffic information and navigation assistance.

Communities west of the Hudson River are particularly likely to see steady, heavy rain, said Bill Potter and Alex Marra of Hudson Valley Weather, noting the tropical feel "as a strong southerly flow ahead of the approaching cold front pulls warm and humid air into the Hudson Valley" with temperatures and dew points in the 70s.
