Boulder siren testing to begin April 6, continue through August

Beginning Monday, April 6, and continuing on the first Monday of each month through August, the Boulder Office of Emergency Management, in partnership with Boulder County and the City of Boulder, will begin audible testing of the countywide emergency sirens. 

The tests will be at 10 a.m. and 7 p.m. each day, on April 6, May 4, June 1, July 6 and Aug. 3. 

The siren tests ensure that all systems and procedures are working properly during the season of peak flood danger, which is typically early spring to late summer.
