Cass County, IN – Residents across Cass County may hear outdoor warning sirens Wednesday morning as part of a scheduled system test.
According to the Cass County Emergency Management Agency, a special test of select outdoor warning sirens will take place at 10 a.m. on Wednesday, December 17. Officials emphasized the activation is not an emergency and is not a countywide test.
The siren testing is being conducted to verify the effectiveness of recent maintenance and repairs made to portions of the warning system. Only specific sirens will be activated during the test, meaning some areas of the county may not hear any sirens at all.
Emergency officials remind residents that outdoor warning sirens are designed to alert people who are outside to move indoors and seek additional information through trusted sources such as local media, weather radios, or official emergency alerts. Sirens are not intended to be heard clearly indoors.
The agency also noted that the sounding of a siren does not necessarily mean a threat has ended once it stops. Siren activations are controlled by county emergency personnel, not the National Weather Service.
Residents who hear sirens during the scheduled test are asked not to call 911 unless they have an actual emergency. The test is part of ongoing efforts to ensure the system functions properly ahead of severe weather seasons.
Cass County EMA says it remains committed to public safety and preparedness across the county.
