Salt Lake City, UT – A powerful December winter storm could leave Utah residents facing snow covered highways, frozen plumbing, dangerous wind chills and power outages lasting several days. With winter 2026/27 approaching, homeowners across Salt Lake City, Salt Lake County, the greater Salt Lake City metropolitan area and communities throughout Utah should prepare before heavy mountain snow, freezing temperatures and dangerous travel conditions threaten their properties.
According to winter safety guidance from the National Weather Service and Utah Division of Emergency Management, winter storms can produce significant snowfall, hazardous ice accumulation, dangerous wind chills and widespread transportation disruptions. Northern Utah and the Wasatch Mountains face substantial snowfall risks, while the Wasatch Front can experience heavy valley snow, freezing fog and rapidly changing road conditions. Southern Utah generally experiences milder winters at lower elevations but remains vulnerable to hard freezes and mountain snowstorms.
Here are 10 critical steps Utah homeowners should take before December snowstorms and extreme cold threaten their properties.
1. Inspect Your Roof Before Heavy Snow Accumulates Utah roofs can experience substantial snow loads, particularly when repeated storms produce heavy snowfall before earlier accumulation has melted.
Inspect shingles, flashing, gutters and attic spaces for existing damage.
Homeowners in Salt Lake City, Sandy, West Jordan and South Jordan should check aging roofing materials and blocked drainage systems.
Residents in Park City, Heber City, Logan, Brian Head and other higher elevation communities should pay particular attention to repeated snowfall and uneven roof accumulation.
Mountain properties may experience significant snow buildup, creating additional structural and drainage concerns.
Watch for sagging ceilings, new cracks, sticking doors or unusual structural noises.
Never climb onto an icy roof. Arrange professional snow removal if accumulation threatens structural safety.
2. Protect Water Pipes Before Extreme Cold Arrives Frozen pipes can burst and cause extensive interior flooding.
Insulate exposed plumbing in basements, crawl spaces, garages and exterior walls.
Disconnect garden hoses, protect outdoor faucets and locate the home's main water shutoff valve.
Older homes in Salt Lake City, Ogden, Provo and Logan may contain plumbing routed through poorly insulated spaces.
Residents in northern Utah, mountain communities and higher elevation valleys should prepare for extended periods of below freezing temperatures.
Vacation homes and seasonal properties face additional risks when indoor temperatures fall during extended absences.
Maintain adequate indoor heating during cold outbreaks, including when traveling.
Open cabinet doors beneath vulnerable sinks during extreme cold to improve warm air circulation.
3. Service Your Furnace or Heating System Before December A heating failure during a Utah winter storm can quickly become a life threatening emergency.
Schedule professional inspections of natural gas furnaces, boilers, heat pumps and other heating equipment.
Replace appropriate filters, verify thermostat operation and check heating fuel supplies.
Residents using propane, fireplaces, pellet stoves or wood burning equipment should arrange inspections and maintain adequate fuel supplies.
Rural Utah households relying on propane should check tank levels and schedule deliveries before major storms make roads difficult to access.
Keep heating exhaust outlets clear of drifting snow.
Never use kitchen ovens, charcoal grills or camping stoves for indoor heating.
4. Prepare for Power Outages Lasting Several Days Heavy snow, strong winds and falling tree limbs can damage electrical lines and utility infrastructure.
Communities across Salt Lake, Utah, Davis, Weber and Cache counties may experience outages when winter storms damage power lines.
Mountain communities can face additional restoration challenges when heavy snowfall blocks access roads.
Keep flashlights, batteries, charged power banks and emergency radios accessible.
Households relying on electrically powered medical equipment should establish backup arrangements.
Portable generators must operate outdoors, at least 20 feet from windows, doors and vents, with exhaust directed away from buildings.
Never operate generators inside garages, basements or enclosed porches.
Residents in isolated mountain areas should identify alternate heating and shelter arrangements before severe weather develops.
5. Build a Winter Storm Emergency Supply Kit Maintain at least three days of emergency supplies, with additional provisions for households in isolated areas.
Store one gallon of drinking water per person daily, nonperishable food, prescription medications, blankets, first aid equipment and pet supplies.
Residents in mountain communities should consider additional provisions if heavy snowfall temporarily closes access roads.
Homes relying on electrically powered private wells should store extra water because pumps may stop functioning during outages.
Keep a manual can opener, flashlights and charging equipment available.
Farm and ranch households should also plan for livestock water, feed access and backup power for essential agricultural equipment.
Households in remote central and southern Utah should prepare for longer travel disruptions when winter storms affect mountain highways.
6. Prevent Ice Dams and Expensive Interior Water Damage Ice dams develop when melting roof snow refreezes near colder roof edges, potentially forcing water beneath roofing materials.
Utah's sunny winter days and freezing nights can create repeated melting and refreezing cycles.
Inspect attic insulation, seal accessible air leaks and maintain appropriate ventilation.
Replace deteriorated weatherstripping around windows and exterior doors.
Clean gutters and inspect downspouts before freezing conditions arrive.
Homes experiencing recurring ice dams should receive professional evaluations.
Mountain homeowners should also identify areas where roof snow may slide suddenly onto decks, walkways, propane equipment or entrances.
Avoid attempting dangerous roof repairs during icy weather.
7. Remove Hazardous Tree Limbs Before Heavy Snow Strikes Heavy, wet snow can break weakened branches, damaging homes, vehicles and electrical infrastructure.
Inspect trees near roofs, garages, driveways and overhead utility lines.
Arrange professional removal of dead or unstable limbs.
Residents in wooded neighborhoods around Cottonwood Heights, Holladay, Bountiful, Park City and Logan should pay particular attention to branches overhanging structures.
Mountain properties surrounded by pine and fir trees may face additional hazards from snow laden branches.
Never approach fallen electrical wires or attempt to remove branches touching power lines.
8. Prepare Snowblowers, Vehicles and Mountain Travel Plans Utah snowstorms can rapidly bury driveways and create dangerous highway conditions.
Inspect snowblowers, shovels and ice melting supplies before December.
Check equipment condition and store fuel safely.
Keep exterior stairways, emergency exits, heating appliance vents and nearby fire hydrants accessible.
Drivers should carry blankets, winter clothing, phone chargers, flashlights, food, water and other emergency vehicle supplies.
Monitor conditions along Interstate 15, Interstate 80, Interstate 70 and Interstate 84, as well as U.S. Highways 6, 40 and 89.
Travelers crossing Parleys Canyon, Little Cottonwood Canyon, Big Cottonwood Canyon and other mountain routes should prepare for sudden closures, heavy snowfall and traction requirements.
Avalanche mitigation operations can temporarily close roads serving popular mountain destinations.
Utah Department of Transportation officials may impose traction requirements on designated routes during hazardous conditions.
Drivers along Interstate 15 through the Wasatch Front should prepare for rapidly changing visibility and icy conditions during heavy snowfall.
Residents in northern and central Utah should also be cautious when freezing fog reduces visibility and creates slick pavement.
Check Utah Department of Transportation road conditions through UDOT Traffic before traveling.
Avoid unnecessary travel during winter storm or blizzard warnings.
9. Test Carbon Monoxide Detectors Before Using Backup Heat Carbon monoxide poisoning becomes a serious winter danger when heating equipment malfunctions or generators are used improperly.
Test smoke and carbon monoxide alarms and replace batteries or devices according to manufacturer instructions.
Heavy snowfall can obstruct vehicle exhaust pipes and heating appliance vents.
Never run a vehicle with its tailpipe blocked by snow.
Keep generator exhaust away from buildings and never use charcoal grills, camping stoves or kitchen ovens for indoor heating.
Residents using fireplaces, wood stoves or other fuel burning heating equipment should ensure chimneys and ventilation systems are properly maintained.
High altitude homeowners should also ensure heating appliances are properly installed and maintained for their elevation.
Anyone experiencing symptoms of possible carbon monoxide exposure should move to fresh air immediately and call 911.
10. Establish a Family Blizzard Emergency Plan Identify where household members can safely shelter if electricity or heating becomes unavailable.
Keep emergency contacts written down and locate warming centers when local officials announce their availability.
Check on older neighbors, residents with disabilities and people living alone.
Monitor National Weather Service forecasts, Utah Division of Emergency Management announcements and Utah Department of Transportation road conditions through UDOT Traffic.
Residents in mountain communities should establish communication plans before heavy snowfall or highway closures restrict travel.
Households near avalanche terrain should monitor official avalanche forecasts from the Utah Avalanche Center and avoid hazardous slopes.
Families should also identify alternate shelter arrangements if prolonged power outages make their homes unsafe.
Why December Preparation Matters for Utah Winter 2026/27 Winter weather risks vary considerably across Utah.
