Heavy Rain, Scattered Flooding Possible Across The Hudson Valley

HUDSON VALLEY, NY — Showers and thunderstorms through the region from Monday night into Tuesday evening could produce locally heavy rain and flash flooding.

"A completely saturated, off the charts, tropical like atmosphere late tonight and early Tuesday will have capabilities of producing heavy downpours with rainfall rates in excess of 1" to 2" per hour," said Bruce Furbeck of First Due Weather.

The National Weather Service issued a hazardous outlook for Orange, Putnam, Rockland and Westchester counties that covers Monday and Tuesday: Showers and thunderstorms could produce locally heavy rainfall that leads to scattered areas of flash flooding, mainly late Monday night and early Tuesday morning. Isolated strong to severe thunderstorms are possible during this time as well.

For Dutchess and Ulster counties, the NWS issued a hazardous outlook for Tuesday: Periods of moderate to heavy rain are possible beginning early Tuesday morning. Locally heavy rain could produce minor flooding of poor drainage, urban and low-lying areas. Additionally, isolated instances of flash flooding are possible, especially in the southernmost portions of the Mid-Hudson Valley and Litchfield County.

This is part of a big cold front.

"Rounds of disruptive thunderstorms will erupt from the Ohio Valley to the Eastern Seaboard from Monday to Tuesday evening as energy surges eastward ahead of a broad zone of low pressure," said AccuWeather Meteorologist Alyssa Glenny.
