Blizzard & Winter Storm Emergency Kit: Complete Prep Guide
A major blizzard can render roads impassable for days, knock out power for a week or longer, and cut off supply chains that most households depend on for daily needs. Unlike more dramatic sudden disasters, a blizzard emergency kit is primarily about sustaining normal life functions: heat, food, water, power, and communication: during an extended period of forced home confinement. This guide covers what to stockpile, how to keep your household warm when heating fails, and the specific winter storm supplies that most households overlook until they need them.
Before the Storm: 48-Hour Prep Checklist
When a blizzard warning is issued, complete these tasks before the storm arrives:
- Fill the gas tank and check tire chains/snow tires
- Withdraw cash: ATMs may be unavailable for days
- Fill bathtubs and sinks with water (pipes may freeze)
- Charge all devices and power stations
- Bring in any outdoor items that could be buried or blown
- Stock medications, pet food, and any perishables needed for the isolation period
- Let all faucets drip slightly in unheated areas to prevent pipe freezing
- Locate your snow shovel, ice melt, and traction equipment
- Check on elderly neighbours, family members, and anyone who may need assistance
Heating When Power Fails
Loss of power in a blizzard is common: and combined with below-freezing outdoor temperatures, loss of heat becomes life-threatening within 12–24 hours for vulnerable individuals. See our complete Off-Grid Heating Guide for detailed product guidance. Summary for blizzard scenarios:
- Mr. Heater Portable Buddy (indoor propane heater): The most practical emergency heating option for apartments and homes without fireplaces; rated for indoor use with ODS safety shutoff; stock 4–6 canisters of 1-lb propane cylinders or a 20-lb tank with adapter
- Wood stove or fireplace: The most reliable long-term option; requires pre-seasoned firewood stockpile (1 cord minimum for a winter season)
- Room consolidation: Heat one small interior room rather than the whole house; significantly reduces heating load and makes any heating method more effective
- Sleeping bags: A 0°F sleeping bag allows safe sleep even if indoor temperature drops significantly; every household member should have one
Food & Water
Food for Blizzard Isolation
A well-stocked pantry that covers 2 weeks of meals is the most important blizzard food preparation. Key considerations:
- Focus on foods that can be prepared without electricity (propane stove) or even without cooking
- Include high-calorie comfort foods: morale matters during extended confinement
- Stock ready-to-eat canned and shelf-stable foods as a no-cook backup
- Have a manual can opener: an electrical opener is useless in a power outage
Water in Blizzard Conditions
- Pipe freeze risk: Unheated pipes can freeze and burst during extended cold; let faucets drip and open cabinet doors under sinks along exterior walls
- If pipes freeze: Do not use open flame to thaw; use a hair dryer (if power is available) or heating pad on the frozen section
- Snow as water source: In a true emergency, snow can be melted for water on a camp stove: melt at least 1 qt of snow per 1 cup of water needed (snow is mostly air); purify melted snow before drinking with filtration or boiling
- Pre-store 1 gallon per person per day × 7 days before blizzard season
Power & Lighting
- Flashlights (LED) × 2 per household + headlamps × 1 per person
- Lithium AA/AAA batteries × 48 (20-year shelf life)
- LED lantern × 2 (for area illumination)
- Candles × 24 + lighters × 4 + matches × 3 boxes
- Portable power station (EcoFlow Delta 2 or similar) for phone charging, medical devices, CPAP
- Portable generator (outdoor use only) if running refrigerator or high-load appliances
- CO alarm × 2 (critical if using any combustion heat source or generator)
Protecting Your Home in a Blizzard
- Roof snow load: Heavy wet snow can exceed roof load limits; if snow accumulates significantly, carefully remove from the edges with a roof rake (do not get on a snow-covered roof)
- Ice dams: Ice dams form at roof edges when warm attic air melts snow, which refreezes at the cold eaves; can cause water backup under shingles; address attic insulation and ventilation to prevent
- Exhaust vents: Clear snow from furnace, water heater, and generator exhaust vents: blocked vents cause CO accumulation
- Garage doors: Wet snow can freeze garage door seals shut; keep spray lubricant accessible
- Carbon monoxide: During blizzards, CO poisoning incidents spike as people use generators, gas stoves for heat, or other combustion devices indoors: always run CO alarms and follow all combustion safety rules

Recommended Products
Mr. Heater F232000 MH9BX Portable Buddy Indoor Propane Heater
The Mr. Heater Portable Buddy is the most recommended indoor emergency heater for households without a wood stove or fireplace: at 4,000–9,000 BTU, it heats rooms up to 225 sq ft, includes an oxygen depletion sensor (ODS) and tip-over shutoff for indoor safety, and works on standard 1-lb propane cylinders or a bulk 20-lb tank via adapter hose. During a blizzard that cuts power and natural gas service simultaneously (rare but possible), this heater operates entirely independently of utility infrastructure. Stock 6–10 one-pound cylinders or a 20-lb tank as your fuel supply. Pair with a CO/propane alarm as a non-negotiable safety measure.
- 4,000–9,000 BTU; ODS safety shutoff; tip-over shutoff
- Indoor-rated; works on 1-lb or 20-lb propane
- 100% utility-independent: works when grid and gas both fail
Snow Joe 323E Electric Single Stage Snow Blower
A snow blower transforms the post-blizzard recovery from a physical ordeal into a manageable task. The Snow Joe 323E handles snow depths up to 10 inches and throw widths up to 13.5 inches: sufficient for residential driveways and sidewalks after most blizzards. At under $200, it is the most affordable effective snow blower available. Electric (cord-connected) means no engine maintenance, no fuel to store, and reliable cold-weather starting: cold start failure is the most common complaint about gas snow blowers. Buy before the first snow of the season; stores sell out rapidly after each storm.
- 10-inch clearing depth; 13.5-inch throw width
- Electric: no cold-start failure; no fuel storage needed
- Under $200: most affordable effective residential snow blower
Blizzard Preparedness FAQ
How long should I prepare to be snowbound during a blizzard?
FEMA recommends a 72-hour minimum preparedness baseline, but major blizzards frequently trap households for 5–7 days or longer: particularly in rural areas where road clearing is slower. The February 2021 Texas freeze trapped millions for over a week. The February 2010 “Snowmageddon” in the mid-Atlantic region left many households snowed in for 5–7 days. A 14-day preparedness baseline is reasonable for households in snowbelt regions: food, water, medications, heating fuel, and power supplies to cover two full weeks without leaving home or receiving deliveries.
At what temperature does my house become dangerous without heat?
The danger threshold varies by household member. Healthy adults can tolerate indoor temperatures down to about 55°F (13°C) with appropriate clothing without health risk. Infants, elderly individuals, and those with certain health conditions (hypothyroidism, cardiovascular disease, diabetes) are at risk at temperatures below 65°F (18°C). A well-insulated home drops approximately 1°F per hour without any heat source at typical winter outdoor temperatures: so a home at 68°F may reach 55°F after 13 hours. This is why an emergency heating solution that activates before the home reaches dangerous temperatures is essential, not optional, for households with vulnerable members.
