Sirens - Outdoor Warning Siren System
The outdoor warning siren system is tested on the last Friday of the month at 9:30 am. The test may be cancelled in some situations depending on the weather and cloud-cover conditions.
Sirens could potentially be sounded for any emergency event, not just tornado warnings. Always get indoors and tune to local media to learn about event details.
Sirens are NOT intended to be heard indoors, but you may hear them depending on proximity and other factors. It's important to have other methods to receive alerts.
Click on the siren map at left to view or print the location of the outdoor warning sirens in Bismarck and surrounding area. There are 23 sirens within Bismarck city limits, and four additional sirens in close proximity, including 2 in the city of Lincoln. All 27 sirens are activated simultaneously as a single system.
We recommend the purchase of a radio with the SAME feature (Specific Area Message Encoding) which means the receiver is capable of turning itself on from a silent mode when the signal for your area is sent out. These radios can be programmed for a specific county (or counties) so you do not receive alerts from areas far away. You should also choose a model that provides you with the option of selecting which alerts you want to receive and which alerts you prefer to deactivate.
