CASS COUNTY, N.D. – During North Dakota Severe Summer Weather Awareness Week, a full-system test of the outdoor siren warning system in Cass County will be conducted on Wednesday, April 24, at 11:15 a.m. Residents are encouraged to review their tornado sheltering plans and practice going to their shelter area.

What to do when you hear the sirens (when a test is not scheduled): Seek shelter indoors and turn on local media (local broadcast channels, radio); follow directions from local officials, including information provided by the National Weather
Service.

Do not assume there is no emergency because skies are clear; there may be a non-weather-related emergency.

Only call 9-1-1 in case of an actual emergency. Please do not use 9-1-1 to ask questions about the siren system; all questions may be routed to the Office of Emergency Management at (701) 476-4068.

The siren structure is an outdoor warning system; therefore, due to high winds and weather conditions, you may be unable to hear the sirens indoors or during an actual event. Cass County Emergency Management recommends signing up for Cass Clay Alerts and having a NOAA All-Hazards Weather Radio with Specific Area Message Encoding (SAME) technology to
provide dependable indoor warning information.
