When do the sirens sound?
Outdoor warning sirens are one method used to alert citizens of a current or potential emergency. To provide a "tornado warning" is a typical use, but outdoor warning sirens may be used for other emergencies as well.

When the sirens sound, go indoors, seek shelter, and monitor local media and your all hazards NOAA Weather Radio if you have one.

Regarding Tornadoes
The Outdoor Warning Sirens will be sounded when:
- A confirmed funnel has been spotted within a 10 mile approach of the community, OR
- A confirmed tornado has been spotted within a 10 mile approach of the community, OR
- The National Weather Service has issued a Tornado Warning for eastern Morton and southwest Burleigh Counties to include the Cities of Mandan and Bismarck and/or Lincoln.

Confirmation of a funnel cloud or tornado may occur through the National Weather Service, trained Law Enforcement Officers, or trained Weather Spotters. Remember, a Tornado Warning means that a tornado has been sighted or indicated by weather radar. A Tornado Watch means that conditions are favorable for the formation of a tornado. The Outdoor Warning Sirens will not be sounded for a Watch.

There is NO "All-Clear" sounded by the outdoor warning sirens. The all-clear will be made over NOAA Weather Radio, local radio stations, and cable TV.

Note: The outdoor warning sirens are tested on the last Friday of each month at 9:30 am.
