The National Weather Service has issued a Winter Storm Warning for the Hamptons and North Fork Wednesday, in effect starting at 7 p.m. and lasting for 24 hours.

A winter storm warning is more severe than a winter storm watch. The National Weather Service states, “A warning is issued when a winter storm is imminent or occurring. If you hear a warning, immediately go home or shelter in place until it is safe to travel again. If you are home, bring in pets and plan to stay inside until you are told it is safe to go out again. Blizzards, extreme cold and windchill can quickly become deadly outside.”

Snow accumulations of 4 to 8 inches are expected Wednesday night through Thursday.

Rain will mix with snow and sleet this evening, and change to all snow before midnight. Snow may be heavy at times later tonight into Thursday morning, before tapering off Thursday evening.

Hazardous travel conditions are expected due to reduced visibility, ice roads and significant snow accumulations.
