Surviving a Winter Storm Power Outage at Home

A winter storm power outage usually arrives with three problems stacked together: falling indoor temperature, no working heat source, and roads too bad to easily get help or supplies. None of these individually is unmanageable, but together, over several days, they get dangerous fast — especially for very young, elderly or unwell household members. The plan is about managing heat loss, avoiding carbon monoxide, keeping food safe and staying informed, roughly in that order.

1. 01

   Check for immediate hazards before anything else. Downed lines, gas smells, or damage from whatever caused the outage — these take priority over comfort.

1. 01

   Close off and insulate one room. Shut doors, hang blankets over doorways and windows, and concentrate the household there rather than trying to heat the whole house.

1. 01

   Protect pipes from freezing. Open cabinet doors under sinks near exterior walls, and let taps drip slightly if a hard freeze is expected, since moving water freezes slower than still water.

1. 01

   Layer clothing before reaching for heat sources. Wool or synthetic layers, hats and blankets do more for comfort per unit of effort than most people expect, and buy time before any heat source is needed at all.

1. 01

   Set up safe heat and light only with carbon monoxide in mind. Never run a generator, camping stove or charcoal indoors, even in a garage with the door open — see the safety section below.

1. 01

   Check on medically vulnerable household members and neighbours. Cold homes are genuinely dangerous for infants, the elderly and anyone with certain health conditions, faster than most people assume.

Any combustion heater, generator or stove that burns fuel produces carbon monoxide, an odourless gas that can kill without warning signs the way smoke does. It must only run outdoors, or in the specific location and ventilation a device is rated for — never in a room, garage, tent or vehicle without dedicated, code-compliant venting. A battery-powered carbon monoxide alarm is worth having in any home that might use backup heating or cooking. For genuinely powerless heating of a single room, see heating one room without power for layering and insulation techniques that don't involve combustion at all.

A full freezer stays safe for roughly 48 hours unopened, a fridge for around 4 hours — keep both closed as much as possible to preserve that window. Favour foods that need no cooking or minimal heating over the first day, since cooking indoors without power has its own carbon monoxide considerations covered in cooking indoors without power. Keep a few days of stored water on hand regardless of outage length, since water systems can also fail during severe winter weather.

Trying to heat the whole house rather than one room, which wastes both fuel and body heat. Running a generator in a garage "for ventilation" — attached garages still allow carbon monoxide into the house. Opening the fridge or freezer repeatedly to check on food, which shortens the safe window. Waiting until the storm is imminent to check on elderly or vulnerable neighbours, rather than checking early and often.

A battery or hand-crank radio keeps you connected to official warnings when mobile networks and home internet may both be down — solar radio with flashlight covers a device that does both jobs from one battery. Weather and road-condition warnings for your specific area are worth checking before the storm arrives, not just during it.

If indoor temperature drops close to outdoor levels despite these measures, or a vulnerable household member shows signs of hypothermia (confusion, slurred speech, shivering that stops), treat it as a medical emergency and get to a warm shelter or call for help rather than continuing to improvise. No amount of layering substitutes for evacuating a home that has become genuinely unsafe.

It can't fix a genuinely failed heating system or a multi-day regional outage on its own, and none of these measures replace a real backup heat source if you live somewhere with severe, prolonged winters — that's a bigger investment decision, not a same-day fix.

Is it safe to burn candles for warmth? Candles produce negligible heat relative to fire risk, especially left unattended overnight — they're a light source, not a heat source.

Should I keep taps running to prevent frozen pipes? A slow drip on vulnerable pipes is usually enough; running taps fully wastes stored water without meaningfully improving protection.
