  • There are about 1,000 to 1,200 tornadoes annually in the United States.
  • There are an average of 50 tornadoes a year in Iowa

If we are under a tornado warning, seek shelter immediately! Most injuries associated with high winds are from flying debris, so remember to protect your head. Then: Go to a pre-designated area such as a safe room, basement, storm cellar, or the lowest building level.

You should not open windows and should have sturdy shoes on when entering your safe place.

If you are not in a sturdy building, possible actions include:

  • Immediately get into a vehicle, buckle your seat belt and try to drive to the closest sturdy shelter. If your vehicle is hit by flying debris while you are driving, pull over and park.
  • Take cover in a stationary vehicle. Put the seat belt on and cover your head with your arms and a blanket, coat or other cushion if possible.
  • Lie in an area noticeably lower than the level of the roadway and cover your head with your arms and a blanket, coat or other cushion if possible.

In all situations:

  • Do not get under an overpass or bridge. You are safer in a low, flat location.
  • Never try to outrun a tornado in urban or congested areas in a car or truck. Instead, leave the vehicle immediately for safe shelter.
  • Watch out for flying debris. Flying debris from tornadoes causes most fatalities and injuries.


Fire Siren

The three sirens are sounded for three minutes straight in the event of a severe weather event. If you hear the sirens, sound for 30 seconds, it is calling fire fighters to the station.

In the event the siren last for 3 minutes, take shelter immediately. The sirens are activated from the fire station or by Linn County Emergency Management once a trained weather spotter identifies a possible tornado or high winds that can cause damage. You should proceed immediately to the lowest level of your home and seek shelter.

In the event you do not have a basement, take shelter in the inner most room of your home.

An all clear siren will sound for 1 minute once the sever weather event has passed.
