Winter storms cost Americans more than $1 billion in property damage every year, according to NOAA. Burst pipes and failed heating systems account for most of those losses. Almost all of it was preventable with prep done before the storm arrived, not scrambling during it.
Each section below covers one room with specific tasks, ranked by what matters most. Three days out or three hours out, you will know where to start.
Before you start: two scenarios to plan for
Grab a notepad or open your phone's notes app. As you walk room to room, write down anything that needs repair or replacement: cracked window seals, dripping pipes, a furnace filter overdue since last spring. Things you have been putting off become real problems at 15 degrees.
Plan for two situations: sheltering at home for two to five days, and losing power for anywhere from a few hours to a few days. Both happen regularly in serious winter storms, and most of the prep below covers both at once.
Step 1: the kitchen
Start here. Food and water both run through the kitchen, so if you only have an hour, spend most of it in this room.
Check your pantry and stock three to five days of non-perishable food: canned soups, dried beans, pasta, peanut butter, and instant oatmeal. Keep a manual can opener within reach. Electric models are useless when the power is out.
Fill your largest pots with water and leave them on the stove. The CDC recommends one gallon per person per day as a minimum. Two gallons per person is a safer target once you factor in cooking and basic hygiene.
Gas stoves work fine during a power outage. If yours is electric, keep a camping stove and sealed fuel canisters in your supplies. Never use an outdoor propane grill or charcoal indoors. Carbon monoxide poisoning from improper indoor heating use kills dozens of people every winter storm season, according to the Consumer Product Safety Commission.
Step 2: the bathrooms
Burst pipes are the most expensive claim most homeowners ever file after a winter storm. Bathrooms are where most of those pipes run.
Pipes along exterior walls freeze first. Open the cabinet doors beneath every bathroom sink so warm air can reach the pipes. If a hard freeze is coming, let a thin trickle of water run from the faucet farthest from your main shutoff. Moving water takes much longer to freeze than standing water does.
Find your main water shutoff valve before the storm, not during it. If a pipe bursts, getting to that valve fast limits the damage. If you are not sure where it is, check the basement, utility room, or near the water heater.
Bathrooms also make a good medication staging area. Stock a two-week supply of any prescription medications your household takes, plus a first aid kit. After a major storm, pharmacies and urgent care clinics can be closed or unreachable for several days.
Step 3: the garage and utility room
Two things in this space will define your winter storm experience: your heating system and your water heater. If either fails mid-storm, you go from inconvenienced to in trouble fast.
Get a licensed technician to inspect your furnace or boiler every fall. A cracked heat exchanger or failing igniter is a non-issue in October. It is a crisis in January. While you are at it, test your carbon monoxide detectors and swap out batteries older than six months.
If you have a backup generator, run a test before the storm arrives and fuel it enough to run 48 to 72 hours. Always operate it at least 20 feet from any window or door. Wrap exposed pipes in the garage with foam pipe insulation, a few dollars per foot at any hardware store, and under an hour to install. It can prevent a lot of expensive water damage.
Step 4: the bedrooms
Pull your warmest blankets and sleeping bags out of storage before the storm hits. If the heating system fails at 2 AM, you do not want to be pulling boxes off a closet shelf in the dark to find them.
Give every household member their own flashlight and put a charged power bank next to each person's charger. When the power goes out, people scatter looking for light. That is when someone trips over something in the dark. Knowing exactly where the flashlight is keeps that from happening.
Bedroom storm prep at a glance
- Warm blankets and sleeping bags pulled out of storage, not buried in the back of a closet
- Personal flashlight assigned to each household member
- Charged power bank next to each phone charger
- Children's coats, boots, and warm layers in a bag near their bedroom door
- Extra socks and gloves in each room for a quick grab
For families with young children, pack a bag with their coats, boots, and warm layers and set it near their bedroom door. Evacuation in a winter storm happens with almost no warning. Having the gear in one known spot takes a real variable out of the equation.
Step 5: the living room
If you have a wood-burning fireplace, get the chimney inspected and cleaned every year. Creosote buildup causes chimney fires, and chimney fires during winter storms happen when roads are icy and fire trucks are already stretched across dozens of calls.
Keep a NOAA weather radio and spare batteries in the living room. Cell towers get overloaded fast during regional storms. A battery-powered radio stays on when everything else goes dark. Research from Oregon State University Extension found that households with battery-powered weather radios make better decisions during outages, largely because they still have access to updated information when their phones are offline.
Throw in some board games, cards, or books. A three-day power outage is long and boring, and that matters more than people expect.
Step 6: the exterior
Finish outside tasks at least 24 hours before a storm is forecast. Working on a roof or a driveway during active snowfall is how accidents happen.
Clear gutters of leaves and debris so melting snow and ice have somewhere to drain. Ice dams form when water backs up under shingles because it cannot exit the gutter, and the resulting interior water damage is expensive. Trim any branches hanging over your roof or power lines. Wet heavy snow can snap them without much warning.
Check the weather stripping on exterior doors. If you can slide a piece of paper under a door without resistance, cold air is getting in and warm air is leaving. Restock your ice melt or sand if supplies are low from last year.
For broader guidance on home structural prep before winter weather, FEMA's Ready.gov winter weather guide and Wikipedia's overview of winter storm classifications are both worth reading. The National Weather Service winter safety page explains the difference between storm watches and warnings, which tells you how fast you need to act.
Pre-storm checklist by room
- Kitchen: 3-5 days of non-perishables, manual can opener, largest pots filled with water, camp stove if you have an electric range
- Bathrooms: cabinet doors open under sinks, faucet trickling during a hard freeze, main shutoff valve located, 2-week medication supply on hand
- Garage/utility: furnace inspected, CO detectors tested and batteries fresh, generator fueled and tested, exposed pipes insulated
- Bedrooms: warm blankets out of storage, flashlights and power banks assigned per person, children's gear bagged near their door
- Living room: weather radio with spare batteries, board games or books, chimney inspected if wood-burning
- Exterior: gutters cleared, overhanging branches trimmed, weather stripping checked, ice melt restocked
Going room by room keeps the task from feeling overwhelming. "Prepare for winter" as a single item is easy to put off. "Open the cabinet doors under the bathroom sink" takes 30 seconds. That difference matters when the forecast shows three days until a storm and you keep putting it off.
Once the physical prep is done, tie it to a broader preparedness plan that covers evacuation routes and family communication. For guidance on what to do once a storm is actively hitting, the power outage preparedness guide and shelter-in-place practices on this site cover both scenarios.
