What to Do When a Tornado Warning Is Issued in the United States | Quick Actionable Ideas and Survival Tips

UNITED STATES — A TORNADO WARNING means take shelter now. Go to a basement, purpose-built storm shelter or small interior room on the lowest floor of a sturdy building. Stay away from windows. Cover your head and neck. Mobile homes, vehicles, highway overpasses and large open rooms are not safe tornado shelters. If someone is injured or trapped, call 911.

The National Weather Service (NWS) distinguishes a Tornado Watch, when a tornado is possible, from a Tornado Warning, when a tornado has been sighted or indicated by radar and danger may be imminent. Do not wait to see a funnel cloud before taking a warning seriously.

12 immediate actions — tornado warning survival checklist

Stop what you are doing and take the warning seriously. Confirm the affected area only if this will not delay sheltering.
Go to the best shelter you can reach immediately. A designated tornado safe room or basement is preferable.
If there is no basement, choose a small interior room on the lowest floor. A windowless bathroom, closet or hallway may be appropriate.
Stay away from windows and outside walls. Do not open windows to “equalise pressure”; this does not protect a building.
Cover your head and neck. Use your arms, cushions, a mattress or a helmet already within reach; do not delay to search for equipment.
Keep children and household members together in the shelter. Bring pets only when doing so does not expose you to danger.
Leave mobile or manufactured homes for sturdy shelter when time and a safe route permit. These homes provide poor protection in a tornado, even when tied down.
Avoid gymnasiums, auditoriums and other wide-span rooms. Follow your workplace, school or shopping centre’s designated shelter plan.
If driving, seek a nearby sturdy building rather than trying to race the tornado. Never shelter under a highway overpass.
If no substantial shelter can be reached, follow the best available local safety advice. Vehicle and outdoor last-resort options carry serious risk; protect your head and do not move into traffic or flooding.
Listen for updated warnings. Use NOAA Weather Radio, Wireless Emergency Alerts, local NWS information or your local emergency authority.
Stay sheltered until the threat has passed, then check for hazards. Avoid fallen power lines, broken gas pipes, unstable buildings and debris.

If a tornado warning is active where you are, take cover instead of reading the rest of this article. The longer explanation is for people preparing a plan or already sheltering.

What does a tornado warning actually mean?

The NWS says a Tornado Watch means tornadoes are possible in and near the watch area. It is time to review the shelter plan, keep alerts accessible and be ready to move. A Tornado Warning indicates a tornado has been sighted or indicated by radar. It requires prompt protective action for people in the warned area.

A Tornado Emergency is the highest NWS tornado alert. It is issued when there is a severe, life-threatening tornado threat with evidence supporting potentially catastrophic impact. The phrase is not just an attention-grabbing headline. If it concerns your location, get into the best available refuge immediately and remain protected.

Warnings are often issued for areas much smaller than watches. Your smartphone may display a polygon, an affected town or a list of communities. Do not spend the first dangerous minute debating whether your street is just outside the shaded map. If the weather or warning indicates danger at your location, shelter rather than standing outdoors to look for a funnel.

Where is the safest place in a house?

A purpose-built FEMA safe room or appropriately designed storm shelter offers stronger protection than an ordinary interior room. A basement is generally a good choice. If none exists, use a small, windowless interior space on the lowest floor and place as many walls between you and the outside as practical.

Get low and cover your head, especially against flying debris and falling material. A bathtub or closet may provide some shielding when it is genuinely interior and away from windows, but there is no universal guarantee that any ordinary room will withstand the most violent tornado. The actual construction and nearby hazards matter.

Do not waste time opening windows. NWS guidance rejects the myth that opening them prevents tornado damage through pressure equalisation. It leaves you closer to flying glass and consumes the time needed to reach shelter.

What if you live on the upper floor of an apartment?

Move towards a designated building tornado shelter or the lowest accessible interior area, if you can reach it without exposing yourself to the storm. Use the building’s emergency plan. Do not remain beside a balcony door, broad windows or exterior stairwell.

If you use a wheelchair or have another mobility limitation, plan an accessible lower-floor refuge with building management before severe-weather season. During the warning, make the safest reachable choice and communicate assistance needs; do not attempt a dangerous transfer down an unprotected staircase as the tornado is arriving.

What if you live in a mobile or manufactured home?

NWS guidance is especially clear that mobile homes and manufactured housing are among the worst tornado shelters. Anchoring or tie-downs do not transform a mobile home into a substantial storm shelter. Identify a nearby sturdy building or designated community shelter and arrange a way to get there during a watch or before the tornado approaches.

Do not wait until winds are tearing apart the site to decide where to go. If the storm is already striking and no safe route exists, avoid entering flying debris and use the safest remaining local refuge while following emergency instructions. There is no safe last-minute formula that replaces leaving early.

Tornado safety at work, school or a shopping mall

Large public buildings can have wide roofs, glass fronts, tall atria and unfamiliar exits. Follow the building’s tornado plan and staff directions. The NWS advises moving to a designated shelter or interior hallway on the lowest level rather than standing in a gym, auditorium, cafeteria or other room with an expansive roof.

In a school, a proper plan assigns teachers to move children to protected rooms and take attendance. It should account for children who need physical assistance, have limited hearing or require medication. A drill that simply moves children to the nearest windowed corridor may not place them in the safest available position.

In a workplace, managers should stop outdoor operations promptly during warnings. Nobody should be asked to continue loading trucks, climbing scaffolds, operating a crane or checking a rooftop while a tornado threatens the site.

Tornado safety when you are in a vehicle

A car cannot be treated as a storm shelter. The safest outcome is reaching a substantial nearby building before the tornado reaches your location. If there is time and a safe route, go to such a shelter. Do not attempt to outrun a nearby tornado in congested traffic or drive towards a visible funnel to obtain a video.

The NWS acknowledges that no single research-based last-resort action suits every vehicle and outdoor circumstance. Some guidance describes staying seat-belted low inside the vehicle with head protection; other guidance mentions a nearby low area such as a ditch when a vehicle is in direct danger. Both alternatives carry serious risks, particularly from flying debris, flooding, lightning, traffic and terrain.

A highway overpass is not a tornado refuge. Winds and debris can be especially dangerous around an overpass, and stopping beneath one can obstruct traffic. Do not pull into a flooded culvert or rush across an active highway as an improvised escape. Follow emergency warnings and seek proper shelter whenever it can still be reached.

If the warning starts while you are outdoors

In a park, sports field, festival, campsite or farm, move towards an enclosed substantial building immediately if one is reachable. Tents, picnic shelters, storage sheds and isolated trees are not reliable places to ride out tornadic wind.

Camping groups should identify a sturdy shelter and evacuation plan before storms form. If forecast conditions are threatening, cancel exposed activities while safe travel remains possible. A tornado may arrive with rain or low visibility, so relying on a group leader to see the funnel is poor preparation.

If no proper shelter is available when the storm is upon you, protect your head and neck and avoid obvious hazards such as traffic, power lines, loose trees and floodwater. Do not assume an open ditch is always safe. The actual terrain and circumstances determine which imperfect option carries less danger.

Children, older adults and people who need assistance

A useful family instruction is short: “Warning means basement or inside room, away from windows, cover your head.” Children should know the shelter room, which adult will help them and how to stay there. They should not be sent across the house for a pet or bag during the warning.

For older adults, residents with disabilities or people needing oxygen or electrical medical equipment, planning at the watch stage is important. Moving to a protected ground-floor area may take time. Keep essential medication and communications within the planned refuge, but do not let collecting them delay the move during an imminent threat.

When family members are apart, do not drive through the storm to reunite. Agree ahead of time that everyone goes to the safest available refuge where they are. Contact one another after the immediate warning passes and communications become reliable.

What should go into a tornado shelter kit?

Battery-powered NOAA Weather Radio or another reliable way to receive warning updates.
Flashlights and spare batteries; avoid candles if gas systems may be damaged.
Shoes sturdy enough to walk over glass and storm debris afterwards.
Prescription medication, water and essential medical devices where feasible.
A charged phone and backup power bank.
Helmets, cushions or blankets that can protect the head and neck.
Identification, contact numbers and a small first-aid kit.
Supplies for infants, pets and anyone with accessibility needs.

Keep these supplies in or near the planned shelter. A kit elsewhere in the building can become useless when seconds matter. It is better to have a few essentials in the correct location than an elaborate kit that requires crossing a windowed room to retrieve.

What to do immediately after the tornado passes

Wait for authoritative advice that the immediate threat has ended. There may be multiple tornadoes or another storm cell. Do not emerge only because the roar has stopped momentarily or because the rain has weakened.

Once safe to leave shelter, look for injuries, structural damage, broken glass, fallen ceilings and damaged utilities. A building that is still standing may have unsafe stairs, exposed wiring or gas leaks. Do not turn electrical devices on where damage or leaking gas is suspected. Move to a safer place if instructed, and call 911 for immediate rescue or medical emergencies.

Stay out of debris piles, unstable structures and flooded streets. Emergency vehicles need clear access. Take photographs for insurance only after the location is safe, and follow county or city instructions about damaged homes, temporary shelters and recovery services.

What if someone is trapped or injured?

Call 911 for serious injuries, immediate danger or a person trapped beneath debris. Provide the exact location, building type, number of people and any known hazards. Do not enter a partially collapsed structure or attempt untrained heavy debris removal that could trigger further collapse.

Provide first aid only when the scene is safe and you are able. Keep an injured person warm and reassured and follow the dispatcher. Do not move someone with a suspected serious neck or spinal injury unnecessarily unless immediate danger requires it.

If phone service is congested, send brief non-emergency messages when possible instead of repeated calls. Do not clog emergency lines to ask whether the tornado warning is over; use NWS or local news for weather information.

Four common situations

The warning arrives at night while everyone is asleep

Wake household members and move directly into the chosen shelter area. Use a flashlight if necessary and keep shoes accessible. Do not stop to watch the weather from a bedroom window. Continue listening to NOAA Weather Radio or an approved alert source.

You are shopping in a large retail store

Follow staff or the building’s tornado shelter plan. Move away from storefront glass and wide-span public areas into a suitable interior space. Do not rush out to a parked car just because the checkout line has stopped.

Your family lives in a mobile-home park

Plan community shelter access before storms arrive, including transport and accessibility arrangements. When a tornado watch is issued, prepare to leave for safe shelter. Waiting until a nearby tornado is visible may leave too little time.

You are driving on an interstate

Seek a nearby sturdy building when a safe route and enough time exist. Do not use a bridge or overpass as shelter. If no safe building can be reached, follow the best locally appropriate last-resort guidance while accounting for traffic, flooding and flying debris.

Preventing avoidable mistakes

Do not open windows to equalise pressure. The NWS says this is not helpful.
Do not take cover under an overpass. It is not a tornado shelter.
Do not stay in a mobile home because it is tied down.
Do not stand beside a glass door watching for the tornado.
Do not assume a warning requires a visible funnel before acting.
Do not travel across town to bring family together during the warning.
Do not assume the first calm moment is the all-clear.
Do not choose an exposed gymnasium when an interior shelter exists.

Prepare before the next tornado watch

Identify your basement, safe room or lowest interior windowless refuge.
Check with your workplace or school about its actual designated shelter.
Arrange an alternative sturdy shelter if you live in a mobile home.
Keep a warning-capable NOAA Weather Radio and phone alerts enabled.
Practise the fastest safe route and include people with mobility needs.
Put shoes, light, head protection and essential medication within reach.
Agree that separated family members shelter where they are.
Know your county and nearby town names for interpreting warning messages.
Plan for pets without allowing pet collection to delay an imminent shelter move.
Review the plan after changes in housing, health, mobility or family arrangements.

Frequently asked questions

Is a tornado watch the same as a warning?

No. A watch means conditions may produce tornadoes; be prepared. A warning means a tornado has been detected or reported and you should act now.

Should I open the windows?

No. The pressure-equalisation idea is a myth and opening windows exposes you to more danger.

Is the bathroom always safe?

An interior, windowless bathroom on the lowest floor can be a reasonable shelter when there is no basement or purpose-built safe room. A bathroom on an exterior wall with a large window may be a poor choice.

Can I shelter under a highway overpass?

No. NWS guidance specifically warns that overpasses do not offer adequate protection and may increase danger.

What if I live in a mobile home?

Arrange to reach a nearby substantial building or storm shelter before the tornado arrives. A mobile home is a high-risk location even when tied down.

Should I call 911 for a tornado warning?

Do not use emergency lines for ordinary weather information. Call 911 for injury, immediate danger or urgent rescue, and use NWS information for warnings.

When can I leave my shelter?

After the warning and local threat have passed, while remaining alert for additional storms, hazards and official instructions.

The rule worth remembering

Watch: prepare. Warning: shelter now. Go low, go interior, cover your head, avoid glass and mobile homes, and remain sheltered until the danger has passed.
