WESTPORT — A winter storm is threatening to dump nearly a foot of snow on the region starting early Tuesday.

Don’t be fooled by clear skies Monday, with temperatures rising to nearly 50 degrees, the National Weather Service says in a “Winter Storm Warning” issued for the region as of early Tuesday.

The storm is expected to start depositing “heavy” snow across the Westport area early Tuesday, with accumulations of between seven to 10 inches before tapering off Tuesday evening, according to the NWS forecast.

Drifting snow is possible with wind gusts clocking up to 35 mph.

There also is a “Coastal Flood Advisory” in effect for the region from 11 p.m. Monday through 2 a.m. Tuesday.

Temperatures during the snowstorm are expected to rise no higher than the mid-30s, but with the wind-chill factor, it will feel as though it’s 20 to 25 degrees, the NWS says.

On Wednesday, the Valentine’s Day forecast is sweeter, with skies clearing, although temperatures also will rise only to the mid-30s and winds may gust over 30 mph.

The outlook for Thursday is basically the same, although the weather service says there is a 40 percent chance of snow showers as clouds move in Thursday night.
