A coastal storm is expected to move into the region Friday night into Saturday with loads of rain, heavy winds and the possibility of some wet snowflakes, forecasters said.

The National Weather Service said the storm could bring two to three inches of rain for Long Island, with the potential for coastal flooding.

"An intensifying low pressure system will track southeast of the region Friday Night into Saturday. This will bring heavy precipitation, gusty winds, minor coastal impacts, and gale conditions on the waters," the weather service said in a briefing Thursday evening.

Winds could reach 35 mph to 45 mph Saturday morning and are expected to be highest on the coast, the weather service said.

Rain will start Friday night but is expected to be heaviest Saturday afternoon, with the possibility of wet snowflakes mixed in.

Friday's high should be about 50 degrees but it will cool down to a high in the mid-40s by Saturday.

Sunday has a 40% chance of showers, and once again it will be mild, with a daytime high of 47 degrees predicted, the weather service said.

Monday, however, brings the sun back — and the daytime high will be just a touch cooler at 44 degrees.

That is well above the mean temperature for this month of 35.6 degrees. The range is 28.2 to 43, according to weather service statistics for Islip that begin on 1963.
