Siren test cancelled tonight due to inclement weather.

The Boulder Office of Emergency Management, in partnership with Boulder County and the City of Boulder, will continue audible testing of the countywide emergency sirens at 10 a.m. on Monday, May 6. The test is the second of the monthly emergency audible siren tests, which take place each year on the first Monday of each month from April through August.

The audible siren tests will occur twice on each testing day, at 10 a.m. and 7 p.m., on May 6, June 3, July 1, and August 5. Should Boulder experience severe weather during one of the planned audible tests, the siren tests for that day may be cancelled.

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. As peak flood risk season approaches, residents are encouraged to: Sign up for emergency alerts at; Review their emergency preparedness plans with family, friends, and coworkers; and Refresh the contents of their home, vehicle, and work emergency supply kits.
