Outdoor Warning Siren Test This Saturday

The Washtenaw County Emergency Operations Center will be conducting a test of 87 outdoor warning sirens on October 7, 2017 at 12:00 Noon. These sirens are tested at Noon on the first Saturday of every month from March through October. If there is a threat of severe weather on the day of a test, it will be cancelled. Except for scheduled testing, the sirens will be activated for the following emergencies: 1.) The National Weather Service has issued a tornado warning. 2.) A severe thunderstorm has been detected with damaging winds of 75 MPH or greater. 3.) A hazardous materials accident requires immediate protective action by the public. 4.) An attack on the United States is imminent, underway or has recently occurred. Warning siren activation is a signal to members of the public to immediately go indoors and monitor local Emergency Alert System media outlets for official information. Washtenaw County’s emergency broadcasters are: WEMU 89.1 FM, WWWW 102.9 FM, WQKL 107.1 FM, WTKA 1050 AM, and WLBY 1290 AM. This test does not include sirens within the City of Ann Arbor.
