Outdoor Warning Siren Testing


Starting with Iowa Severe Weather Awareness week the City of Storm Lake will be testing the City's outdoor warning system weekly, provided that weather is not threatening. In the event that the weather is threatening sirens will not be tested and any activation of the sirens would be an actual warning.

Sirens are tested every Saturday at noon starting in late March and running into the Fall.

During testing the City's Volunteer Fire Department will monitor each siren location to ensure that it is working properly and if needed facilitate the repairs of the siren in a timely manner.
