Monday’s winter storm watch was upgraded to a blizzard watch by the National Weather Service on Sunday morning, Jan. 25.

The blizzard watch is in effect from Monday afternoon through Tuesday evening, according to the weather service. A blizzard could blanket Trumbull and the rest of the greater New York City metropolitan area with heavy snow and blowing snow that leaves one to two feet of snow — even higher in some areas.

Winds in the area could be 20 to 30 mph with gusts up to 50 mph, according to the weather service, which also warns of visibility less than a quarter of a mile. Temperatures on Monday and Tuesday are expected to be in the low-20s.

The heaviest of the snow and strongest winds are expected overnight on Monday into Tuesday, according to the weather service.

Expect “extremely dangerous travel due to heavy snowfall and strong winds — with whiteout conditions likely,” according to the weather service’s blizzard watch bulletin. “Secondary and tertiary roads may become impassable. Strong winds may down power lines and tree limbs.”

A blizzard watch means there is a potential for falling and/or blowing snow with strong winds and extremely poor visibilities that could lead to whiteout conditions and make travel dangerous.

Malloy to activate Emergeny Operations

Governor Dannel P. Malloy is ordering the State Emergency Operations Center  to be activated at 4 p.m. on Monday, Jan. 25, in anticipation of a potentially historic blizzard.

In addition, he will hold a news briefing from the EOC at 10 a.m. that morning to provide updates on the state’s preparations for the forecasted winter storm.

“Based on the forecasts we’re looking at now and assessing the situation with state emergency management officials, I have directed the state’s EOC to be activated at 4 p.m. on Monday,” Malloy said. “We urge Connecticut residents to take necessary  precautions. The state will continue to monitor, prepare and stay in front of this storm and react quickly.”

The state EOC, staffed by state emergency management personnel and representatives of the state’s major utility companies, will remain open throughout the duration of the storm.
