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.
