If a tornado warning has been issued for your location in the United States, go immediately to the safest available shelter: a properly designed storm shelter or safe room, a basement, or a small interior room on the lowest floor of a sturdy building. Stay away from windows and outside walls. Crouch low and protect your head and neck from flying debris.
Do not go outside to see whether a funnel cloud is visible. Tornadoes can be hidden by darkness or rain, develop rapidly and damage buildings before a person has time to react. A warning is a reason to take protective action now, not to wait until a tornado crosses your street.
This guide explains what to do when there is a tornado in the United States, whether you are at home, in a school, office, factory, car, mobile home, store or hotel. For an actual event, check current alerts from the National Weather Service and your local emergency management agency. For immediate life-threatening emergencies, call 911 after taking cover when it is safe to do so.
Quick answer: the actions that matter most
- Tornado warning for your address: stop other activities and move promptly to a storm shelter, safe room or basement.
- No basement: choose a small windowless interior room or hallway on the lowest floor of a sturdy building. Stay away from broad-span rooms and exterior walls.
- Protect your body: crouch low, shield your head and neck with your arms, and use a sturdy cover, helmet or thick padding if already nearby.
- In a manufactured or mobile home: leave it for a substantial building or designated storm shelter before the tornado reaches you; a mobile home is not a reliable tornado refuge.
- In a car, tent or outdoors: seek a sturdy building immediately if safely reachable. Do not shelter under a highway overpass. Last-resort outdoor or vehicle choices are dangerous and depend on actual conditions.
- If you are in a school or workplace: follow the designated severe-weather shelter route, not a windowed corridor or a large gymnasium.
- After the storm: monitor for additional warnings; avoid damaged buildings, fallen power lines and gas leaks.
The NWS guidance on what to do during a tornado and NWS explanation of watches and warnings support these priorities.
First, understand the difference between a Tornado Watch and a Tornado Warning
Tornado Watch: prepare before trouble arrives
A Tornado Watch means atmospheric conditions are favourable for tornadoes in and near the watch area. That does not mean a tornado is confirmed above your house. It is a signal to review your shelter location, charge devices, bring people indoors if appropriate and stay ready for fast changes.
If you live in a mobile home or somewhere without a safe shelter, the watch period may be your opportunity to relocate to a designated substantial shelter before conditions become severe. Confirm which nearby facility is open rather than assuming any public building will admit people during a storm.
A watch may cover several counties or states. Your action should combine the broad watch with updated local warnings and your own shelter situation.
Tornado Warning: take cover now
A Tornado Warning means a tornado has been observed or is indicated by radar in the warned area. The warning can apply to a smaller geographic area and may last only a short time. Take shelter immediately instead of calculating whether the plotted track crosses your house exactly.
Read the warning’s affected locations and latest update, but do not delay moving to your safe place to study a map. Tornado tracks can shift, and damaging winds or flying debris may occur beyond the visible funnel.
A Tornado Emergency is a particularly urgent warning designation for an exceptionally dangerous tornado threat. It strengthens the requirement for immediate maximum protection. It is not a new kind of tornado and does not imply that ordinary tornado warnings can be ignored.
Where should you shelter in a house?
If your home has a purpose-built tornado safe room or properly designed storm cellar, go there. Otherwise use the basement where accessible. If the home has no basement, select a small, windowless room on the lowest floor, away from outer walls and doors. An interior bathroom, closet or hallway may be appropriate.
Get low. Put as many sturdy interior walls between you and the outdoors as possible. Cover your head and neck; a bicycle helmet, thick blanket or mattress can offer additional protection from debris if you can obtain it without delaying shelter. Put on shoes when there is time, as broken glass and nails may be present afterward.
A bathroom is not magically safe because it contains a bathtub. Its value depends on its position inside the building, construction and whether it is the best available room. A large bedroom with windows on two walls is not a better option merely because it feels comfortable.
Do not go to the upper storey to watch the storm. Do not stand by a window, and do not open windows in an attempt to equalise pressure. The old advice to open windows is a dangerous myth and wastes time.
Apartments, offices, stores and hospitals: choosing a safer room
In an apartment building, follow the property manager’s severe-weather shelter plan if one exists. A basement or lowest-level interior refuge is generally preferable to a high-floor corner apartment with wide windows. Do not enter an underground garage if it is exposed or not designated and safe; structural and flooding hazards also matter.
In a shopping centre, warehouse, factory, school or hospital, follow trained staff to the designated shelter. Large open-span areas such as gymnasiums, auditoriums and some big-box retail spaces can be especially vulnerable to roof damage. A smaller interior room on the lowest level, away from glass, is often safer if no specially designed refuge is available.
If you are responsible for a group of children, visitors or patients, avoid stopping in a doorway to count possessions. Use the established shelter procedure and then account for people in the protected area. If the building has a designated safe room, its signage and local emergency plan take priority over casual internet suggestions.
Mobile homes, RVs and trailers: why early relocation is essential
Mobile homes and manufactured homes can be moved or destroyed by tornado winds, even when anchored. They are not the same as a substantial building or engineered safe room. If you live in one, identify a nearby substantial shelter before severe weather season and know when to go there.
A Tornado Watch or other credible local threat may be a time to leave for that refuge if the route is still safe. When a Tornado Warning is already in effect and the tornado is close, do not automatically start a long trip through the storm. Seek the best available immediate safety option according to local emergency instructions and conditions.
A recreational vehicle, camping trailer or tent is also an unsafe tornado shelter. Do not rely on tying it down or parking beside a tree. A person camping in a park should identify the park’s designated storm shelter or suitable substantial building before camping.
What if you are driving when a Tornado Warning arrives?
A vehicle does not provide reliable tornado protection. The preferred action is to reach a nearby substantial building or designated shelter if safely possible, before the tornado reaches you. Do not intentionally drive towards a visible funnel and do not rely on outrunning a tornado through traffic.
If the tornado is imminent and there is no accessible sturdy shelter, there is no single last-resort option that is safe in every situation. Depending on terrain, traffic, flooding and debris, official NWS guidance describes staying belted in a stationary vehicle while covering your head or moving to a distinctly lower location away from the road if it can be reached safely. Both options carry serious risks.
Do not shelter under an overpass or bridge. Wind and debris may be funnelled through the structure, and vehicles stopping there block roads needed by others. A ditch that is filling with water is not a safe refuge either. Flooding and lightning can turn an improvised low spot into a separate danger.
The NWS vehicle and outdoor tornado safety advice explains why last-resort decisions depend on the immediate environment. The general objective remains to avoid ever being caught without a sturdy shelter.
If you are outside or in an open public place
Move to a substantial building if it is close enough to reach safely. Do not take shelter inside a lightweight shed, picnic canopy or temporary shelter. Trees, overhead lines and loose signs can become hazards in severe wind. Once you reach the building, go to its interior lowest-level refuge, not the glass entrance.
If you cannot reach a substantial shelter and a tornado is about to strike, protecting your head from flying debris is essential. Follow local emergency directions and choose the least dangerous available option; no blanket instruction to lie in a ditch guarantees safety, particularly if flash flooding is possible.
At stadiums, festivals and large venues, follow the preannounced shelter plan promptly. Waiting until thousands of people move simultaneously can produce crowding and exposure along open corridors. Venue managers should plan well before the first warning, but visitors must act when staff direct evacuation to internal shelter areas.
Tornado at night: when you cannot see the hazard
Nighttime tornadoes can be difficult to notice visually. Your main protection is a reliable alert method that can wake you, such as compatible Wireless Emergency Alerts on a charged phone and a weather radio with alert capability. Have more than one method when possible; a single device may fail during a power or network outage.
Keep a pair of shoes, a torch, any necessary medications and a way to cover your head near the sleeping area during forecast severe weather. Know the route to your safe room without lights. Do not send a child outside to verify weather conditions.
If a warning arrives during sleep, wake household members and move directly to shelter. A text to relatives can wait until everyone is in the protected place. Tornadoes do not need to be visually confirmed by residents to be dangerous.
How to prepare a household tornado plan
A useful tornado plan is measured by how quickly the people who live in the building can carry it out. Pick one best shelter, one backup, and a communications process. Practise moving there without using exterior doors or long corridors that expose people to glass.
- Find the safest designated shelter or lowest-floor interior room in your specific building.
- Agree who assists small children, people with mobility needs and those who may not hear audible warnings.
- Keep shoes, flashlights, helmets or head padding, prescription medicines and emergency contacts accessible.
- Arrange a reliable alert system: NWS messages, NOAA Weather Radio and local emergency notifications.
- Give children a short instruction such as “When we hear tornado warning, we go to this room, get low and cover our heads.”
- If you live in a manufactured home, identify a substantial nearby shelter and a realistic time to reach it.
- Plan for pets without delaying protection; have carriers or leads ready before the storm.
- Check the weather forecast before outdoor events and long-distance road travel.
- Know who will provide updates after the storm if phone calls cannot connect.
You do not need to purchase complicated equipment to recognise the correct shelter location. Structural safety and access are more important than a bag full of gadgets. Families can use NWS tornado preparedness guidance to practise these decisions.
Children, schools and people who need assistance
A teacher should not have to improvise a shelter route when a warning is issued. Schools normally designate internal safe areas and conduct drills; staff must follow the school’s current procedures. A school bus on the road needs instructions from its transport and emergency operations plan, not an assumed rule that the bus itself is shelter.
Students should know the difference between a practice drill and a real warning, but the physical motion can be familiar: stop, move to the designated location, crouch and protect the head. In a large group, calm, short instructions are often more effective than explaining the storm’s science during evacuation.
For people who use mobility equipment, shelter access should be worked out ahead of time. If a person cannot crouch, identify ways to protect the head and body from debris without unsafe transfer. Medical needs, sensory sensitivity and language barriers must be included in the emergency plan.
What not to do when you hear a tornado siren
Outdoor warning sirens are a local alert tool, not the only way to know if a tornado threatens you. Some communities do not operate sirens. Their sound may not carry inside a home, and sirens may be used for several hazardous conditions. Do not wait for a siren if the NWS has already issued a warning.
Likewise, a quiet moment or lack of visible rotation does not cancel an active warning. Follow updated NWS and local notices until the immediate threat has passed. Additional tornado-producing storms may follow in the same weather system.
After the tornado: hazards remain on the ground
Once you are no longer under immediate tornado threat, check for injuries and serious hazards. If emergency help is needed, call 911 and give responders the best available location details. If you are in a damaged building, move only as safely as possible and avoid unstable walls, broken stairs and hanging debris.
Do not touch fallen wires or anything in contact with them. Avoid damaged gas lines, sparks, smoking near suspected leaks and entering an unstable structure. Wear strong shoes and protective clothing when moving through debris. Keep children out of damaged areas and only perform first aid you are trained to provide.
Send a short message to family to say you are safe if mobile service works. Follow official instructions on road closures, shelter access, drinking water and electrical service. Photograph property damage for insurance only when doing so does not expose you to injury.
The NWS guidance after a tornado emphasises continuing weather awareness, contact with relatives and caution around debris and damaged buildings.
Worked example: a family in Oklahoma during an evening warning
Imagine a family in a one-storey house without a basement. A Tornado Watch is in effect, so they identify a windowless interior closet and place shoes and a torch nearby. Later the phone and weather radio report a Tornado Warning affecting their neighbourhood.
The family moves immediately to the closet, crouches, protects their heads and stays away from windows. They do not go into the garden to look for the funnel. They remain protected while the local alert is active, then check official updates before examining damage. This is a fictional illustration, not a description of a particular tornado.
Now consider a visitor staying in a mobile home nearby. The proper earlier decision is to relocate to an identified substantial shelter while the trip is still safe, rather than assuming the manufactured home’s bathroom offers the same protection as a concrete storm shelter. Location and building type change the action.
Mistakes that make tornadoes more dangerous
- Opening windows to equalise pressure. Do not waste warning time doing this.
- Driving under an overpass. Overpasses are not tornado shelters.
- Standing beside the window to film the tornado. Flying debris and shattered glass can cause serious injury.
- Remaining in a mobile home without an earlier shelter plan. These buildings are especially vulnerable.
- Treating a Watch as if it were a Warning, or vice versa. Prepare during a watch; shelter immediately during a warning.
- Going to a school gym or big retail floor because it is spacious. Large open-span roofs can be vulnerable.
- Assuming the tornado has passed because thunder stops. Continue to monitor the latest alerts.
Frequently asked questions
Where is the safest place during a tornado in the United States?
A purpose-built storm safe room or appropriately engineered shelter offers the strongest option. Otherwise choose a basement or small, windowless interior room on the lowest floor of a substantial building.
Should I open my windows?
No. It does not protect the building and wastes time that should be used taking cover.
Is a bathtub safe?
An interior bathroom on the lowest floor may be a reasonable refuge, but a bathtub is not universally safe. Room position, construction and the presence of windows matter.
What is the emergency phone number for tornado injuries?
Call 911 in the United States for an immediate threat to life, serious injury, fire or other emergency.
Can I drive away from a tornado?
Avoid attempting to outrun or approach a tornado. If a sturdy nearby shelter is safely reachable, go there early; if the tornado is imminent, follow official last-resort vehicle and outdoor guidance appropriate to your situation.
