(Cass County, ND) -- On Wednesday, April 28th at 11:15 a.m, during North Dakota Severe Weather Awareness Week, there will be a full-system test of the outdoor siren warning system in Cass County. Residents are encouraged to conduct a tornado drill at this time to practice their tornado sheltering plans. 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); hearing a siren does not mean you should evacuate. 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.
