Long Island weather: Winter storm warning for East End

On the heels of a few inches of snow early Friday comes a system packing more of a punch for Saturday, forecasters say.

Areas in Suffolk east of the William Floyd Parkway could see 4 to 8 inches of dry, powdery snow, blowing and drifting as wind gusts could reach 25 mph, the National Weather Service said late Friday afternoon. That area is under a winter storm warning in effect from 7 a.m. Saturday through 1 a.m. Sunday. Snow-covered roads and visibilities reduced to half a mile or less will make traveling hazardous in the area.

Western Suffolk County is under a winter weather advisory during that same time period, with 3 to 6 inches of snow forecast, as of Friday. That also means to expect hazardous driving conditions that call for cautious driving, the weather service said.

Nassau County is looking at possible accumulation of 1 to 3 inches.

The weather service warned on Twitter that there is still some uncertainty regarding forecast snow totals on Saturday.

Bill Korbel, News 12 Long Island meteorologist, however, said one thing does seem certain: “There will be more snow on the east end of Long Island, perhaps more than half a foot, than the west end.”

A slight shift of the storm’s track to the northwest would increase amounts across the Island, while a shift farther east would lower them, he added.

Those in the storm warning area are advised to travel only in an emergency, the weather service said, and in that case, be prepared with an extra flashlight, food and water in your vehicle.

Temperatures will be in the 20s.

The system will be moving northeast across the area Saturday morning, with snow becoming heavy at times in the afternoon to evening over eastern Suffolk, the weather service said. Snow should be ending in the evening hours from west to east.
