Outdoor Warning Sirens

Outdoor warning sirens are considered an outdoor warning system that prompts anyone outdoors to seek shelter. Outdoor warning sirens are not intended for citizens indoors; rather, the Waukee Fire Department recommends citizens utilize a weather radio and tune into their local news channel for up-to-date weather information.

Activation Criteria

The City of Waukee shares the same outdoor warning siren criteria that our neighboring cities use. Outdoor Warning Sirens will be activated by Westcom Communications for any Tornado Warning that is in the Waukee Fire Department’s response district when:

  • Warnings are issued by the National Weather Service
  • Tornado or funnel cloud reported by a trained spotter (law enforcement, fire department official or emergency management agency).
  • Sirens will also be activated for straight line winds (70 Miles per Hour or Higher) in the Waukee Fire Department’s response district, as issued by the National Weather Service.

Warnings are issued by the National Weather Service (Johnston, Iowa) and are received by Westcom Communications who notifies the Waukee fire department via radio.


Outdoor warning sirens shall be tested on the first Saturday of each month at 12:00 p.m. (Noon).

If a severe weather watch or warning is in effect for the Waukee area during the monthly noon test, the sirens should not be tested that day. Outdoor warning siren tests will resume on the next scheduled monthly date.

Testing may be suspended during the winter months (December – February) when ice or sub-zero temperatures could damage the siren system.
