Washtenaw County warning siren testing to resume March 7

I previously reported on the imminent testing of the city’s siren system; Washtenaw County will resumeĀ testing its siren system (which is independent of the city’s system) this month as well.

The county’s sirens are tested at noon on the first Saturday of every month from March through October. This means the first test will be at noon this Saturday, March 7.

Except for scheduled tests, the county’s sirens will be activated when:

  • The National Weather Service has issued a tornado warning
  • A severe thunderstorm has been detected with damaging winds in excess of 70 MPH
  • A hazardous materials accident requires immediate protective action by the public
  • An attack on the United States is imminent, underway or has recently occurred

If you hear sirens and you’re not sure whether it’sĀ a scheduled text, tune into one of the county’s emergency broadcasters.
