At approximately 1:00 p.m. on Wednesday, May 27, the City of Johnston will be sounding their Outdoor Warning Sirens. The testing should take approximately one hour. Notification will be provided on Polk County Emergency Management’s Facebook page once the testing is complete. Please do not call 9-1-1. This is only a test. Direct all testing questions to Polk County Emergency Management Agency’s 9-1-1 Coordinator.
