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 at 10 a.m. on Monday, April 1. The test is the first 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 April 1, 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 canceled.
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. Used to alert residents to potential danger from a flood or other immediate threat, there are 29 outdoor warning sirens in place across Boulder County, including in Boulder, Erie, Jamestown, Lafayette, Louisville, Lyons, Marshall, Eldorado Springs, Superior and the University of Colorado Boulder.
As peak flood risk season approaches, residents are encouraged to:
§ Review their emergency preparedness plans with family, friends, and coworkers; and
§ Refresh the contents of their home, vehicle, and work emergency supply kits.
