A nor’easter is forecast to bring heavy rains, coastal flooding, beach erosion, some snow, and damaging strong winds that may cause power outages on Long Island on Monday and Tuesday, experts said.

The National Weather Service (NWS) issued a coastal flood advisory for Nassau and Suffolk counties from 5 a.m. Monday to 7 a.m. Tuesday. The advisory warned that flooding of up to 1 ½ feet above ground level is expected in vulnerable waterfront areas.

“Heavy rain during the times of high tide will likely exacerbate street flooding in coastal communities,” Upton-based NWS meteorologists said in the advisory. “Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding.”

The storm is forecast to dump up to two feet or more of snow on parts of upstate New York, but less than an inch of the white stuff is expected on the Island.

Four- to 7-foot waves will cause minor beach erosion and flooding during high tide, NWS said. Scattered downed tree limbs and power lines may cause some power outages in the area, the agency warned. Gusts up to 50 mph are possible on the East End.

Once the storm clears the area Wednesday, the forecast for the rest of the week calls for temperatures in the high 40s to low 50s with a mix of sun and clouds before another chance of rain Friday and Saturday.
