The National Weather Service has issued a blizzard watch for southern Fairfield County, New York City, Long Island, southern Westchester, Middlesex and New London counties.

A blizzard watch means there is a potential for falling and/or blowing snow with strong winds and extremely poor visibility, which can lead to whiteout conditions and make travel very dangerous.
The storm is expected to start late Monday night through Tuesday evening and snow accumulations could be from 12 to 18 inches. Damaging wind gusts are possible which could lead to power outages. The gusts could be up to 40 to 50 miles per hour, and up to 60 miles per hour in southeastern Connecticut. Temperatures are expected to be in the upper 20's.
