Columbus, OH – A powerful December winter storm could leave Ohio residents facing snow covered highways, frozen plumbing, dangerous wind chills and power outages lasting several days. With winter 2026/27 approaching, homeowners across Columbus, Franklin County, the greater Columbus metropolitan area and communities throughout Ohio should prepare before heavy snow, freezing rain and damaging winds create dangerous conditions.
According to winter safety guidance from the National Weather Service and Ohio Emergency Management Agency, winter storms can produce significant snowfall, hazardous ice accumulation, strong winds and widespread transportation disruptions. Northeastern Ohio faces additional lake effect snow risks, while central and southern communities can experience dangerous combinations of snow, sleet and freezing rain.
Here are 10 critical steps Ohio homeowners should take before December snowstorms threaten their properties.
1. Inspect Your Roof Before Heavy Snow Accumulates Heavy, wet snow can place substantial weight on roofs, especially when freezing rain follows earlier snowfall.
Inspect shingles, flashing, gutters and attic spaces for existing damage.
Homeowners in Cleveland, Mentor, Ashtabula and communities near Lake Erie should pay particular attention to repeated snowfall and uneven accumulation.
Older homes throughout Columbus, Cincinnati and Dayton may also require inspections of aging roofing materials.
Watch for sagging ceilings, new cracks or unusual structural noises. Never climb onto an icy roof.
2. Protect Water Pipes Before Freezing Temperatures Arrive 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 Cleveland, Toledo, Akron and Youngstown may contain plumbing routed through poorly insulated spaces.
Maintain 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 Boiler Before December A heating failure during a major Ohio winter storm can quickly become a household 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 fireplaces, pellet stoves or wood burning equipment should arrange chimney inspections and cleaning when necessary.
Keep outdoor heating exhaust outlets clear of drifting snow.
Never use kitchen ovens or outdoor cooking equipment for indoor heating.
4. Prepare for Power Outages Lasting Several Days Heavy snow, freezing rain and strong winds can bring down trees and electrical lines.
Wooded neighborhoods across Cuyahoga, Summit, Franklin, Hamilton and Montgomery counties may experience outages when ice covered branches damage utility infrastructure.
Rural communities may face additional restoration challenges when fallen trees block 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.
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 rural northeastern Ohio and communities affected by heavy lake effect snowfall should consider additional provisions if roads become impassable.
Homes relying on electrically powered private wells should store extra water because pumps may stop functioning during outages.
Keep emergency supplies accessible without requiring travel during dangerous conditions.
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.
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.
Avoid attempting dangerous roof repairs during icy weather.
7. Remove Hazardous Tree Limbs Before Snow and Ice Strike Heavy snow and freezing rain 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 Cleveland, Akron, Canton, Columbus and Cincinnati should pay particular attention to branches overhanging structures.
Never approach fallen electrical wires or attempt to remove branches touching power lines.
8. Prepare Snowblowers, Vehicles and Emergency Access Ohio snowstorms can rapidly bury driveways and create dangerous road 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 and other emergency vehicle supplies.
Monitor conditions along Interstate 71, Interstate 75, Interstate 70, Interstate 77 and Interstate 90.
Residents near Lake Erie should be especially cautious when lake effect snow bands sharply reduce visibility.
Avoid unnecessary travel during blizzard warnings or periods of dangerous blowing snow.
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.
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, Ohio Emergency Management Agency announcements and OHGO road conditions.
Residents in rural communities should establish communication plans before heavy snowfall restricts travel.
Families should also identify alternate shelter arrangements if prolonged power outages make their homes unsafe.
Why December Preparation Matters for Ohio Winter 2026/27 Winter weather risks vary considerably across Ohio.
Cleveland, Mentor, Ashtabula and northeastern Ohio face significant lake effect snow risks when cold air moves across Lake Erie.
Toledo, Sandusky and northwestern Ohio can experience strong winds, blowing snow and hazardous travel across open areas.
Columbus, Newark, Lancaster and central Ohio may encounter heavy wet snow, freezing rain and widespread commuter disruptions.
Cincinnati, Dayton and southwestern Ohio can experience rapidly changing precipitation types, including snow, sleet and damaging ice.
Akron, Canton, Youngstown and the eastern Ohio hills face additional risks from freezing temperatures, icy roads and accumulating snow.
Ohio's location near Lake Erie and within the path of major winter storm systems can create sharply different conditions across the state. One community may experience heavy snow while another receives freezing rain or lighter accumulation.
Although this preparedness guide does not predict a specific December 2026 blizzard, significant winter storms remain a recurring seasonal threat.
Waiting until a winter storm warning is issued can leave households scrambling for heating fuel, emergency supplies, backup power and snow removal equipment.
For Ohio residents, completing these 10 preparations before December storms develop could mean the difference between safely weathering severe winter conditions and facing frozen plumbing, heating failures, expensive property damage or dangerous emergency travel.
