Forecast: 'Uncertainty' over developing nor'easter's impact

While local meteorologists say a developing nor'easter is likely to track far enough south that it won't have a major impact on Long Island, the National Weather Service says there's still potential for several inches of snow, 50 to 60 mph wind gusts, coastal flooding, and "significant beach erosion" on ocean beaches and along the Twin Forks.

The storm is forecast to hit Wednesday into Thursday, the service said in a hazardous weather outlook, which also referred to "forecast uncertainty" on the storm's details.

As of late Monday afternoon, the forecast indicated rain starting Wednesday morning, with the highest chance during or right after the morning rush, followed by 1 to 2 inches of snow Wednesday night into Thursday morning, said Lauren Nash, weather service meteorologist in Upton. Winds are expected to pick up during the day Wednesday, she said, with strongest gusts of 35 to 45 mph Wednesday evening, and continuing into Thursday afternoon. .

The storm is forecast to track to the south of Long Island, but the question is by how much, Nash said.

If the storm tracks more to the north, Long Island could see "a good amount of precipitation, winds and coastal flooding," said Mike Layer, also a weather service meteorologist in Upton.

The service also said there was a potential for "storm force winds" Wednesday into Thursday, and "diminishing to gales for Friday" for Long Island's coastal waters, including Long Island Sound, Peconic and Gardiners bays and South Shore bays and inlets, according to a hazardous weather outlook issued Monday afternoon.
