Tornadoes are violently rotating columns of air extending from thunderstorms to the ground. They can develop rapidly, travel at high speeds, and cause catastrophic damage. The United States experiences more tornadoes than any other country, particularly in "Tornado Alley" stretching from Texas to South Dakota, though tornadoes can occur anywhere.
Unlike hurricanes that allow days of preparation, tornadoes may provide only minutes of warning. Effective tornado safety requires advance preparation: knowing where to shelter, having supplies ready, and understanding warning systems. When warnings come, there is no time to plan.
Understanding Tornado Threats
Tornado Watch means conditions are favorable for tornadoes. Be alert and ready to take shelter. Review your plan, monitor weather closely, and prepare to act quickly.
Tornado Warning means a tornado has been sighted or indicated by radar. Take shelter immediately. This is not time to look outside or gather belongings.
EF Scale rates tornado intensity from EF0 (light damage) to EF5 (incredible destruction). You cannot determine intensity until after the tornado passes. Treat all tornado warnings seriously.
Timing: Peak tornado season varies by region. Spring and early summer are most active in southern states; summer in northern states. However, tornadoes can occur any time of year, including winter.
Identifying Safe Shelter
Know your shelter location before storms threaten. When warnings come, go immediately without hesitation.
Best shelter: Underground storm cellar or basement. Get under sturdy furniture, away from windows.
No basement: Interior room on lowest floor. Closets, bathrooms, or hallways away from exterior walls. The more walls between you and outside, the better.
Manufactured homes: Mobile homes are extremely dangerous in tornadoes regardless of tie-downs. Leave for a substantial building or storm shelter. Know where the nearest shelter is before storms threaten.
At work or school: Know the designated shelter areas. Practice tornado drills. Interior hallways away from large rooms (gyms, auditoriums) are typically safest.
In a vehicle: Vehicles are dangerous in tornadoes. If you can safely drive to sturdy shelter, do so. If not, get out and lie flat in a low area (ditch) away from the vehicle. Do not shelter under overpasses.
Storm shelters: Purpose-built above-ground safe rooms and underground shelters provide excellent protection. Consider installing one if you live in tornado-prone areas.
Recognizing Warning Signs
Technology provides most warnings, but know natural signs too.
Severe weather alerts from weather apps, NOAA Weather Radio, local TV, and emergency alert systems provide official warnings. Enable alerts on your phone.
Natural signs: Dark, greenish sky. Large hail. Loud roaring sound (like a freight train). Visible rotating cloud base or debris cloud. Sudden calm after a thunderstorm, then wind shift.
Do not rely solely on sirens. Outdoor warning sirens may not be audible indoors. They are meant to warn people outside to seek shelter and information. Have multiple warning methods.
During a Tornado
When a warning is issued or you observe signs of tornado, act immediately.
Go to your shelter immediately. Do not delay to grab belongings or look outside.
Protect yourself by getting under sturdy furniture. Cover your head and neck with your arms. Use mattresses, cushions, or blankets for additional protection from debris.
Stay away from windows. Flying glass is a major cause of tornado injuries. Interior rooms have more walls between you and broken glass.
Stay in shelter until the storm passes. Tornadoes can seem to pass then return, or multiple tornadoes can occur. Wait for official all-clear.
If caught outside with no shelter available, lie flat in the lowest area you can reach, covering your head. Ditches or low spots offer some protection from flying debris. Stay away from trees and vehicles.
After the Tornado
After the immediate danger passes, hazards remain.
Check for injuries. Administer first aid. Call emergency services for serious injuries.
Watch for hazards: Downed power lines, gas leaks, unstable structures, sharp debris, and broken glass. Do not enter damaged buildings.
Document damage with photos for insurance before cleanup. Contact your insurance company promptly.
Help neighbors if you can do so safely. Check on elderly and vulnerable individuals.
Monitor for additional storms. Tornado-producing weather systems often create multiple tornadoes.
Advance Preparation
Preparation before tornado season saves lives when warnings come.
Identify shelter locations at home, work, school, and places you frequent. Everyone in your household should know where to go.
Practice drills. When severe weather is possible, practice getting to shelter quickly. Time how long it takes. Identify obstacles.
Emergency kit in shelter: Water, first aid, flashlight, sturdy shoes, phone charger, weather radio, whistle (to signal rescuers if trapped).
Helmets: Bicycle or motorcycle helmets provide significant head protection from debris. Keep them accessible near your shelter.
Safe room: Consider a FEMA-compliant safe room if you live in tornado-prone areas. These can be installed in existing homes or built into new construction.
Regional Considerations
Tornado Alley (Central US): Highest frequency of strong tornadoes. Most communities have storm shelters and siren systems. Tornado preparedness is part of local culture.
Southeast US: High tornado risk, often with less warning time and more nocturnal tornadoes. Hills and trees can obscure approaching storms.
Other regions: Tornadoes can occur anywhere in the US. Less frequent does not mean safe. Communities outside traditional tornado zones may have less awareness and fewer shelters.

- Mobile home residents know nearest shelter
- Insurance policy reviewed
Recommended Gear
- NOAA Weather Radio
Automatic alerts even at night. Battery backup essential.

Keep near shelter for walking through debris after.
Frequently Asked Questions
Should I open windows before a tornado?
No. This myth has been debunked. Opening windows wastes time and may allow more debris inside. Get to shelter immediately.
Can I outrun a tornado in my car?
Sometimes, but it is risky. Tornadoes can change direction and travel over 60 mph. Driving conditions during tornadic storms are dangerous. If you can see the tornado and it is not moving left or right (it is coming toward you), drive perpendicular to its path. Otherwise, abandon the vehicle for sturdy shelter or low ground.
Is a highway overpass safe?
No. Overpasses create wind tunnel effects and offer no protection from debris. This is a dangerous myth. A ditch is safer.
What about pets during tornadoes?
Bring pets to shelter if you can do so without delay. Have carriers ready. Keep them leashed or contained. Never risk your life trying to find a pet during a tornado.
How much warning will I have?
Average warning time is about 13 minutes, but varies from seconds to over 30 minutes. Some tornadoes form so quickly they have no warning. This is why advance preparation is essential.
Do tornadoes hit cities?
Yes. The myth that tornadoes avoid cities is false. Large cities have experienced devastating tornadoes. Tall buildings are not protection.
