A snow alert has been issued for the five boroughs ahead of an overnight storm that’s expected to affect the Friday morning commute, the New York City Department of Sanitation said.

The storm is expected to bring light amounts of snow to the area, but its timing could snarl traffic and make traveling more treacherous than usual.

The alert goes into effect at 12 a.m. Friday, the agency said.

A snow alert is not a weather forecast but rather a call to city sanitation crews to prepare for possible precipitation accumulating on the boroughs’ 6,500 miles of streets.

The AccuWeather forecast calls for up to 3 inches of snow in the city, 3-6 inches on eastern Long Island and parts of Connecticut, and 1-3 inches in areas north and west.

The precipitation will arrive as rain Thursday night, changing over to snow during the overnight hours. It will be at its heaviest from 4 a.m. to 9 a.m.

A winter weather advisory has been issued through late Friday morning for parts of central and southern New Jersey.

The snow will clear out by Friday afternoon, and the weekend is expected to be mostly sunny with highs in the mid-40’s.
