Severe thunderstorms and damaging winds
Ohio often experiences strong thunderstorms that can bring damaging straight-line winds, hail, lightning, heavy rain, downed trees, blocked roads, and power outages.
Midwest preparedness
Ohio Disaster Preparedness Guide
Ohio faces a mix of Midwest and Great Lakes hazards, including severe thunderstorms, tornadoes, flooding, winter storms, lake-effect snow in northern counties, extreme heat, and weather-related power outages.
Preparedness overview
Ohio preparedness starts with planning for rapidly changing weather. Spring and summer can bring damaging winds, lightning, hail, tornadoes, flash flooding, heat, and outages. Fall and winter can bring snow, ice, cold, and lake-effect snow in areas near Lake Erie. Households should use local alerts, know safe shelter locations, keep basic supplies ready, plan for medications and devices with help from appropriate professionals, and follow instructions from local emergency management, public health, transportation, and utility officials.
Ohio
Common hazards to plan around
Tornadoes
Tornadoes can occur in Ohio, especially during severe weather seasons, and require households to know where to shelter quickly, away from windows and on the lowest practical level.
Flooding and flash flooding
Heavy rain can cause river, stream, urban, and flash flooding across the state. Low-water crossings, basements, and flood-prone roads need special attention during preparedness planning.
Winter storms and ice
Snow, sleet, freezing rain, ice, and extreme cold can affect travel, heating, communications, and household routines throughout Ohio.
Lake-effect snow in northern Ohio
Communities near Lake Erie can receive localized bands of heavy snow that create sharp differences in road conditions over short distances, especially in Northeast Ohio snowbelt areas.
Extreme heat
Hot, humid weather can strain households, older adults, outdoor workers, pets, and people without reliable cooling, especially when heat overlaps with outages.
Power outages
Outages can follow thunderstorms, wind, ice, snow, heat-related demand, or equipment problems. Preparedness should include lighting, charging, food safety, communications, and backup plans.
Preparedness priorities
- Sign up for local emergency alerts and keep a weather radio or backup alert method available.
- Choose a safe shelter area at home for tornadoes and severe wind, and practice getting there quickly.
- Build a basic emergency kit with water, shelf-stable food, lighting, batteries, chargers, first-aid basics, and copies of key information.
- Make a household communication plan that includes children, older adults, pets, and anyone who may need extra help.
- Prepare for outages with flashlights, charged battery banks, safe food plans, and a way to check on local utility updates.
- Keep vehicles winter-ready before cold weather and check official road information before travel during snow or ice.
- Review insurance documents and home inventory information before storms or flooding, and ask qualified professionals about coverage questions.
