How to Stay Warm Without Power During a Winter Storm

You will see a winter storm coming. That has never been the problem.

Winter storms are among the best-forecast events in the country. The National Weather Service issues watches days ahead. Local news counts down to it. Nobody is surprised.

The problem is what happens afterward. Roads close. Ice brings down a line. Crews work through a backlog, and your street may not be near the top of it. A winter power outage is measured in days, not hours.

And cold compounds. Every hour without heat makes the house harder to warm back up.

Good winter storm preparedness is less about the forecast and more about the three days after it.

Why winter storms are different from other emergencies

Most emergency guidance is written around evacuation. Grab a bag, get in the car, go.

Winter inverts that. Roads are the dangerous part. So the guidance is the opposite of a hurricane or a wildfire. You are staying put, and you need to be comfortable doing it.

That changes what belongs in your kit. Portability matters less. Warmth matters far more. A kit you can carry for a mile is worth less in January than a kit that keeps four people warm in one room for three nights.

There is a second scenario worth naming, though. Winter is also the only disaster that regularly catches people mid-commute. A storm that arrives an hour early can strand you twenty miles from anywhere. That calls for a separate kit, in the trunk, and we will get to it.

What should be in a winter storm emergency kit?

A winter power outage kit needs a few things a general emergency kit does not.

• Warmth. Sleeping bags, emergency blankets, and hand warmers. This is the category most kits under-serve.
• Multiple light sources. In January, darkness arrives by five. One flashlight is not enough for a house.
• Food that needs no cooking. If the power is out, your range may be out too.
• Water stored in advance. Well pumps stop without electricity. City water can lose pressure.
• A weatherband radio. Cell towers have backup power, but not unlimited backup power.
• First aid. A clinic visit may not be possible for two days.

Our winter storm and blizzard emergency kits are built around that list, in a few sizes depending on household.

How do you stay warm without power?

This is the question that matters most, and it has a genuinely good answer.

Pick one room and close the rest. Choose the room with the fewest exterior walls. Interior rooms hold heat far better than a living room with three windows.

Hang blankets over the windows. Glass is where most of your heat leaves. A blanket over a window does more than people expect.

Everyone sleeps in that one room. Pets included. Body heat in a small space is real heat, and it is free.

Wear a hat indoors. You will look ridiculous. You will also be warmer than anyone else in the house.

Eat and drink regularly. Your body needs fuel to generate heat. Skipping meals in a cold house makes you colder.

Open your faucets to a slow drip. Moving water resists freezing. This is the step that turns a cold weekend into just a cold weekend, rather than a plumbing bill.

Why carbon monoxide is the real winter risk

This section is not about a product, and it is the most important part of this article.

Carbon monoxide kills people every winter during power outages. Not from the storm. From how they tried to stay warm.

Generators get run in garages. Charcoal grills come inside. Gas ovens get left open with the door down. Camp stoves come in from the porch.

The rules are simple and worth following exactly.

• Run generators outdoors only, at least 20 feet away from the house, never near a window, door, or vent.
• Never bring a grill or camp stove indoors, including into a garage.
• Never heat a home with a cooking appliance.
• Candles are the other one. They are not a carbon monoxide risk, they are a fire risk, and a multi-day outage is when a forgotten candle finds the curtains.
• Keep a battery-operated carbon monoxide detector.

That last one matters more than it sounds. A hardwired detector stops working in exactly the outage where you need it. A battery unit costs about twenty dollars.

What to keep in your car in winter

Roughly half of winter emergencies happen on the road rather than at home. A car emergency kit covers the vehicle itself. These items cover you.

• A blanket, plus a spare hat and gloves, in the car from November onward.
• A charged power bank.
• Water and a few high-calorie snacks.
• An ice scraper and snow brush.
• Sand, non-clumping cat litter, or a traction mat under a spinning tire. Clumping litter turns slick once it gets wet.
• At least half a tank of fuel. Fuel is heat if you end up sitting for hours, and a fuller tank leaves less room for the condensation that can freeze in a fuel line.

What to do if you get stranded

Stay with the vehicle. This is standard National Weather Service guidance and it saves lives. Your car is shelter, and it is far easier for a plow or a trooper to spot than a person walking in blowing snow.

Run the engine for about ten minutes an hour to warm up, and clear snow away from the exhaust pipe first. A blocked tailpipe pushes exhaust into the cabin, which brings us back to carbon monoxide. Open one window slightly to let in air.

Tie something bright to the antenna or door handle. Turn on the dome light at night when the engine is running.

And move a little. Clapping your hands and shifting your feet keeps circulation going without producing the sweat that later makes you colder. The CDC also advises against eating snow, because it lowers your body temperature.

Our full guide to what to do when your car breaks down covers the roadside side of this in more detail.

When should you check your winter kit?

Every fall, before the first storm of the season. The easiest anchor is the weekend you change your smoke detector batteries.

Test the lights. Check expiration dates on food and water. Replace the batteries in your carbon monoxide detector. Confirm the car kit is actually in the car, not in the garage where it migrated in July.

If the power went out tonight and stayed out until Thursday, which room would your household sleep in?

Frequently asked questions

How long should a winter emergency kit last?

Three days is the standard minimum for food and water. In rural areas or places where crews take longer to reach you, a week is a better target.

Do I need a generator?

Not necessarily. A generator solves a specific problem, usually a medical device or a well pump. For warmth and light, a well-stocked kit is safer and far cheaper.

Can I use my fireplace during a power outage?

Yes, if the chimney has been inspected and swept. A blocked flue is a carbon monoxide risk and a fire risk.

What about frozen pipes?

Keep faucets dripping, open cabinet doors under sinks to let warm air reach the pipes, and know where your main shutoff valve is before you need it.

Should pets have their own supplies?

Yes. Pets need water, food, and warmth on the same timeline you do, and they are often overlooked. Our pet emergency kits cover cats and small dogs.

The short version

You will see the storm coming. Use those days.

Fill some water. Check the batteries. Pick the room you would all sleep in. Put a blanket in the car. Then let it snow.

Peace of mind, packed and ready.
