HUDSON VALLEY, NY — A coastal storm is bringing a prolonged period of heavy rain and then strong, gusty winds to the Hudson Valley Monday and Tuesday, and locally severe flooding is possible.

The National Weather Service said the lower Hudson Valley, NYC, northeastern New Jersey and southwestern Connecticut should expect 3 to 5 inches of rain, but some locations could get 5 to 7 inches.

Also, several small rivers and streams in northeastern New Jersey, the lower Hudson Valley, southwestern Connecticut, and the Bronx are expected to reach minor to moderate flood stage in the next 24 hours, the NWS said at 6 p.m. Monday as showers and thunderstorms brought locally heavy rainfall and lightning strikes.

The NWS said the rapidly developing low-pressure system south of Long Island is expected to produce heavy rainfall across the region until Wednesday. Rainfall rates may exceed one inch per hour at times. The heaviest rainfall is expected to occur late Monday into Tuesday.

A flash flood watch has been issued for Orange, Putnam, Rockland and Westchester counties Monday evening through Tuesday afternoon. In addition, hazardous outlooks have been issued for Dutchess and Ulster counties, and for Orange, Putnam, Rockland and northern Westchester.

A coastal flood watch has been issued for southern Westchester, which was hard-hit a month ago by tropical storm Ida. One foot and locally as much as two feet of inundation above ground level is expected in vulnerable areas near the waterfront and shoreline.

In the lower Hudson Valley, flooding is possible in urban and poor drainage areas, fast-responding rivers and small streams.

New York City's emergency management issued a travel advisory for Monday and Tuesday that warned of flooding and strong winds.

"This event may cause flooding in the city, including on highways, streets, underpasses, as well as other poor drainage or low-lying spots," Andrew D'Amora, the incoming acting commissioner for emergency management, said in a statement. "New Yorkers should give themselves additional travel time and take the appropriate precautions if they must move about the city during the storm."

Gale and storm warnings are now in effect for all marine waters Tuesday into Wednesday.

Toward the end of the storm, strong wind gusts up to 50 mph could bring down tree limbs and power lines.

• Flash Flood Threat: Monday night into Tuesday evening.
• Strong Wind Threat: Late Tuesday afternoon and Tuesday night.
• Coastal Flooding Threat: High tide cycles Tuesday afternoon into Wednesday.

In Dutchess and Ulster counties, the NWS warns that total rainfall amounts of 1 to 4 inches may lead to ponding of water on roads in low-lying and poor drainage areas.
