Winter weather warning for Long Island: up to 8 inches of snow
A winter weather warning is in effect for Long Island Monday, with anywhere from 6 to 8 inches of snow expected, forecasters said.
The warning is in effect from 5 a.m. to 7 p.m. Monday.
Earlier, the service had predicted just 2 to 5 inches of snow, but the 9:54 p.m. winter weather message upped the totals and said sometimes heavy snow would fall in the morning and early evening.
The change came late Sunday night as National Weather Service officials said a low pressure system passing south and east of Long Island on Monday was expected to "push heavier precipitation closer to the coast," said Joe Pollina, a meteorologist with the National Weather Service in Upton.
Temperatures are expected to fall into the lower 30s early Monday, and with winds blowing 10 to 15 mph, visibilities may be "a half mile or less at times Monday morning into the early afternoon hours," the National Weather Service said.
A light rain or rain-snow mix should begin after midnight, and as the precipitation gets heavier, it should change to all snow by daybreak, forecasters said.
Expect slippery travel during the morning commute, the weather service said.
"The wet snow may add extra weight to tree branches and power lines . . . potentially causing isolated power outages," the weather service said.
Meteorologists are also keeping an eye on another storm system expected to affect Long Island on Wednesday, and with this one, "there is the potential for significant precipitation," according to a hazardous weather outlook issued Sunday by the weather service.
The forecast calls for a wintry mix at this point, but "the main question" is where the rain-snow line will fall, weather service meteorologist Lauren Nash said.
