Act now
If you are under a tornado warning, seek shelter immediately!
- If you can safely get to a sturdy building, then do so immediately.
- Go to a safe room, basement, or storm cellar.
- If you are in a building with no basement, then get to a small interior room on the lowest level.
- Stay away from windows, doors, and outside walls.
- Do not get under an overpass or bridge. You’re safer in a low, flat location.
- Watch out for flying debris that can cause injury or death.
- Use your arms to protect your head and neck.
Plan ahead
Live in or plan to visit a tornado-prone area?
- Know the signs of a tornado, including a rotating, funnel-shaped cloud; an approaching cloud of debris; or a loud roar—similar to a freight train.
- Sign up for your community’s warning system. If your community has sirens become familiar with the warning tone.
- Pay attention to weather reports. Meteorologists can predict when conditions might be right for a tornado.
- Identify and practice going to a safe shelter in the event of high winds. The next best protection is a small, interior, windowless room on the lowest level of a sturdy building.
