Lamont Activates Cold Weather Protocol as Arctic Blast Sends Temperatures Plunging

Governor Ned Lamont activated Connecticut’s first Severe Cold Weather Protocol of the winter season Thursday as an arctic blast sent temperatures plunging 10 to 20 degrees below normal across the state.

The protocol, which remains in effect through December 9, triggers the opening of emergency warming centers and expanded shelter capacity for vulnerable populations facing potentially life-threatening conditions.

“We want everyone to take this cold snap seriously,” Lamont said in a statement. “These temperatures can be dangerous, especially for our most vulnerable neighbors. Please check on elderly family members, bring pets inside, and know that warming centers are available.”

Wind chills in the single digits are expected across much of the state through the weekend, with overnight lows approaching zero in some areas. The National Weather Service issued wind chill advisories for all eight Connecticut counties.

Under the protocol, municipalities must ensure adequate shelter capacity and warming centers for residents without housing. The Department of Housing coordinates with local emergency management offices to track bed availability and connect individuals with services.

State officials urged residents to:

• Check on elderly neighbors and family members
• Bring pets and outdoor animals inside
• Allow faucets to drip slightly to prevent frozen pipes
• Keep emergency supplies including flashlights, batteries, and blankets accessible
• Dress in layers if traveling outside

The Connecticut Department of Transportation increased salt and sand distribution on roadways and positioned crews for rapid response to any weather-related incidents.

Social service agencies reported increased demand for warming supplies and emergency shelter beds ahead of the cold snap. United Way 211, the state’s helpline for social services, saw call volume spike as temperatures began dropping.

“This is when our partnerships with shelters and service providers really matter,” said Housing Commissioner Seila Mosquera-Bruno. “No one should be forced to weather these conditions without adequate protection.”

The protocol represents the state’s formal mechanism for coordinating cold weather response across agencies and municipalities. It was established following several severe winters that highlighted gaps in emergency shelter coordination.

Forecasters predict temperatures will moderate somewhat by mid-week, though another arctic system may bring additional cold later in December.
