The City of Ann Arbor started its annual tornado siren test program today at 1:00 p.m., in celebration of Paczki Day and because it's the second Tuesday of March.

The City of Ann Arbor Siren Warning System has 22 sirens throughout Ann Arbor, designed to be activated in case of a tornado warning, nuclear attack, hazardous materials spill, or other reasons as needed by the city's Office of Emergency Management. The sirens are tested on the second Tuesday of each month from March through November, except when inclement weather threatens.

Please call the Office of Emergency Management at 734-794-6980 if you were outdoors and did not hear the sirens on the scheduled time and day of the testing. The next test in Ann Arbor is scheduled for April 12, 2011.
