Manchester, New Hampshire – A late-winter arctic outbreak is forecast to bring dangerous cold and subzero wind chills to New Hampshire from Friday through Monday, increasing the risk of frozen pipes, heating system strain, and cold-related emergencies statewide.
According to the National Weather Service and NOAA’s Climate Prediction Center, a surge of arctic air will spread across the Northeast, Mid-Atlantic, and parts of the Midwest beginning Friday, Feb. 6. The coldest conditions are expected through Sunday night into Monday, with wind chills across much of New Hampshire falling well below zero, particularly in northern areas and higher elevations.
Forecast guidance shows much-below-normal temperatures lingering into early next week, with gusty winds amplifying the cold. These conditions may lead to frostbite on exposed skin in as little as 10 to 30 minutes during peak overnight and early morning hours.
Extended periods of below-freezing temperatures significantly increase the risk of frozen and burst pipes, especially in older homes common across New Hampshire. Pipes located in basements, crawl spaces, exterior walls, and unheated garages are considered most vulnerable during multi-day cold outbreaks. Across the broader region, Lake Erie is now nearly 100% frozen, highlighting the intensity and persistence of the cold air mass affecting the eastern United States.
State and local officials urge residents to insulate exposed plumbing, seal drafts around doors and windows, and maintain consistent indoor heat, even when leaving home. Letting faucets drip slightly and opening cabinet doors can help prevent pipes from freezing. Authorities caution against using open flames, torches, or fuel-burning heaters indoors to thaw pipes due to serious fire and carbon monoxide risks.
Cold weather safety guidance also recommends limiting time outdoors, covering exposed skin, and ensuring pets and livestock have adequate shelter. Additional cold weather advisories or warnings may be issued as the weekend approaches.
