Long Island weather: Strong winds and heavy rain for Christmas

Long Islanders will be greeted Christmas morning to a weather equivalent of a lump of coal, with the National Weather Service predicting strong winds and around two inches of rain.

A high wind warning has been issued for Long Island from 6 p.m. Thursday through 10 a.m. Friday. South winds of 25 to 40 mph are expected, with gusts as high as 67 mph possible on Suffolk County's East End, the weather service said.

The weather service warned of "scattered to numerous downed trees, tree limbs and power outages," and "dangerous travel conditions for high-profile vehicles."

Nassau County Executive Laura Curran urged residents to avoid travel Thursday evening, secure outdoor decorations and items, and have extra batteries handy. Outages can be reported to PSEG Long Island at 800-490-0075.

Minor flooding and beach erosion are also possible.

A coastal flood advisory was issued for all of Long Island's South Shore from 11 p.m. Thursday to 11 a.m. Friday.

"Some roads and low-lying properties including parking lots, parks, lawns, and homes and businesses with basements near the waterfront will experience minor flooding," the weather service said.

"Brief minor coastal flooding" is also possible in southwestern and eastern Suffolk during the early-morning high tide on Friday, the weather service said.

The heaviest rain is likely to fall between around 11 p.m. Thursday and 11 a.m. Friday, the weather service said.

Long Island may see rain later than other parts of the region.

Temperatures are expected to drop to about the low 40s by Friday evening, the weather service said.

There is a slight chance of rain and snow showers Friday night, the weather service said. And ice could form Friday night, when temperatures are expected to plunge into the 20s.

The weather should clear for the weekend, which is expected to be sunny with lows in the 20s and highs in the 30s, the weather service said.
