Dangerous cold is expected in New Hampshire in the days ahead. Here's some tips on how to stay safe, and where to turn for help as we move into winter.
How to stay safe and spot signs of hypothermia
During past periods of extreme cold, state officials have urged people to stay inside if at all possible and to prepare for potential power outages. They recommend keeping an emergency kit stocked with about three days' worth of supplies, including blankets, flashlights and extra batteries.
For those who are unable to find a safe place to stay inside, this guide from the National Health Care for the Homeless Council has tips on how to stay safe if you must be outdoors during extremely cold weather — though they strongly advise finding a safe indoor space if at all possible.
This guide from the CDC also includes advice on how to avoid, spot and treat hypothermia.

Where to find shelter
Melanie Haney leads East Coast Evolution Leadership, which oversees the Warming Center for Stafford County and a shelter in Manchester.
She said it’s important to check official sources, like the actual website or Facebook pages of organizations such as shelters, because she has seen search engine AI answers provide incorrect information about shelter hours or opening dates.
A state directory of shelter options is available at this link. You can also try calling 211 or visiting 211nh.org. You can also try contacting your local welfare office, using the contact information listed here.
The Strafford County Willand Warming Center is open as needed throughout the winter, at 30 Willand Drive in Somersworth, including Nov. 27 and 28. For more information on hours and availability, check their Facebook page, call 603-742-2709 or text “willand” to 855-935-4402.
The Littleton Winter Shelter will open Dec. 1, with 12 beds available. Contact the shelter at 603-999-7602 or email chloe.duff@littletonwintershelter.org.
We will update this page as more information becomes available about warming shelters. If you want to share information about a shelter with us, email voices@nhpr.org.
Where to donate cold weather supplies
Waypoint, an organization that serves unhoused and at-risk youth, has information on how to donate needed supplies here.
The Upper Valley Haven, located in White River Junction, Vermont, has a wish list of needed food, toiletry and other items.
Hundred Nights Shelter in Keene is also looking for cold weather supplies, boots and other items.
How to heat your home safely
Heating equipment is a leading cause of fire in New Hampshire. But there are ways to minimize the threat.
New Hampshire’s fire marshal recommends keeping anything that can burn at least 3 feet away from heating equipment and turning portable heaters off before leaving the room or going to bed. They also urge people not to use an oven to heat their home and never use generators indoors. It’s also a good idea to check your fire alarms and carbon monoxide detectors to make sure they're working properly.
The National Weather Service recommends wrapping pipes with insulation and sealing windows to keep heat indoors. If your pipes are located in a cabinet, it helps to open the cabinet doors to allow warm air to reach the pipe. Keeping a slow stream of water running through your faucets can also help keep pipes from freezing.
Don't forget about pets or other animals
Pet owners will also need to take extra precautions this weekend. Lauren Seymour, a veterinary technician in Hopkinton, said in an earlier conversation with NHPR that unless pets are acclimated to below-zero cold, they should only go outside to go to the bathroom.
"I would bring all pets inside," Seymour said. "Cats, for sure. Indoor-outdoor cats, I would try and keep them inside. There's not going to be a lot of warm places to go this weekend. And any outdoor rabbits or anything, I would absolutely bring inside."
Backyard chickens are another story. New Hampshire State Veterinarian Steve Crawford previously told NHPR that flocks should stay in their coops. Bringing birds indoors can pose risks to human health, he said.
Owners should make sure the birds have plenty of deep, dry bedding, walls and a roof to protect them from the wind. They should also have access to fresh water that isn’t frozen and calorie-rich food. Chickens will roost together for warmth, Crawford says.
Livestock owners should do the same: providing animals with enough bedding, food, water and wind protection for the extreme cold.
