Winter Weather Advisory Issued For Long Island

The National Weather Service has now issued a winter weather advisory for Long Island with the season's first accumulating snowfall on the way.

The advisory will be in effect from 6 a.m. Saturday until 6 a.m. Sunday. A total of 4-6 inches of snow is expected across the entire island, except for the South Fork, which will likely see 2-4 inches.

A winter weather advisory means periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use caution while driving, the NWS says.

The snow will start falling Saturday morning and then accumulating snow is expected to continue for much of the day.
