How to prepare for a winter storm

A winter storm rarely kills with cold alone. Holding heat without power, keeping pipes from bursting and heating a house without carbon monoxide.

Winter storms are unusual among disasters in that the weather itself is rarely what harms people. The cold outside is survivable and well understood. What causes the deaths is what happens inside a cold house: an improvised heater, a generator in the wrong place, a driveway cleared too fast by someone whose heart was not up to it.

So the preparation is mostly about being able to stay warm for several days without burning anything indoors, and about the house surviving it too.

The three problems, in order

ProblemWhat it doesWhat prevents it
Losing heatHouse drops below liveable in a day or twoOne insulated room, layers, bags rated for cold
Carbon monoxideKills within hours, without warningNever burn fuel indoors; battery CO alarm
Frozen pipesBursts flood the house when it thawsHeat reaching the pipes, water moving, mains shutoff known

Before the season

Find your main water shutoff and test that it turns. Ten seconds of knowledge that saves a house.

Insulate the pipes that run through unheated space — crawl spaces, garages, exterior walls — and disconnect outside hoses before the first hard freeze. The full method.

Put a battery CO alarm on each sleeping floor and test it. Hardwired alarms stop when the power does.

Service the heating and clear the vents. Blocked flues are the other half of the carbon monoxide problem.

Stock for a week without shops or roads: water, food that needs no cooking, medication, formula, pet food, and the batteries.

Prepare one room — small, interior if possible, on a lower floor, with a door that closes. That is where the household lives if the heat fails.

When the power goes

  1. Consolidate into the prepared room. Close doors to everywhere else, cover windows at night, block the gap under the door.
  2. Dress in layers with a hat, including indoors and in bed. Most heat loss is a solved problem with wool and a closed door.
  3. Eat and drink warm things. Hydration matters as much in cold as in heat, and it is easy to forget.
  4. Keep pipes moving — a slow drip on the vulnerable runs — and if it gets very cold with no heat at all, shut the water off and drain the system.
  5. Check the fridge rules, and use the outdoors as a cooler only in a sealed container. How to hold heat without power.

Ice storms are their own category

Freezing rain is the winter event that removes infrastructure rather than blocking it. A quarter-inch of ice brings down branches; half an inch brings down lines and poles, and restoration in those conditions runs for days or weeks.

  • Assume a multi-day outage, not an evening one.
  • Stay out from under loaded trees and lines, which fail without sound.
  • Do not drive. Freezing rain removes traction completely, and salt stops working at low temperatures. Preparing for an ice storm.

On the road

  • Do not travel during a warning unless there is no alternative.
  • Keep the tank above half all season: fuel is heat if you get stuck.
  • Carry the winter kit — blankets, water, food, light, shovel, sand, phone power.
  • If you get stuck, stay with the vehicle, keep the exhaust pipe clear of snow, and run the engine only a few minutes at a time. Trapped in a vehicle.

  • Battery carbon monoxide alarm

    CO is the single largest killer in winter outages, it cannot be smelled, and a hardwired alarm stops working exactly when the risk starts.

  • Zero-degree sleeping bags

    One warm room with proper bags gets a household through a multi-day outage without burning anything indoors.

  • Weather radio with alerts

    Ice storm warnings and the outages that follow arrive overnight, and this is the season where the phone runs out first.

Frequently asked questions

  • What actually causes most winter storm deaths?

    Not exposure in the open. The larger causes are carbon monoxide from improvised heating, traffic collisions on ice, heart attacks during snow clearing, and falls. Almost all of them come from decisions made indoors or in a driveway, not from being caught in a blizzard.

  • Is an ice storm worse than a blizzard?

    Usually, for infrastructure. Freezing rain loads power lines and trees until they come down, and the resulting outages last days to weeks in temperatures that make a house uninhabitable fast. Snow closes roads; ice removes the grid.

  • How do I keep pipes from bursting?

    Keep heat reaching them and keep water moving. Open cabinet doors under sinks on exterior walls, let vulnerable taps drip, keep the house above 55°F even when empty, and disconnect outdoor hoses before the first freeze.

  • Can I heat with the oven or a grill indoors?

    No. A gas oven, charcoal grill, camping stove or generator indoors produces carbon monoxide that can kill within hours, and it is odourless. Nothing that burns fuel belongs inside a house without a permanent vent to the outside.
