Boulder County, Colo. – The Boulder Office of Emergency Management (OEM) will begin testing of the countywide emergency sirens at 10 a.m. on Monday, April 4. The test is the first of the annual season of monthly emergency siren tests, which take place on the first Monday of each month from April through August. The siren tests will occur twice on each testing day, at 10 a.m. and 7 p.m., on April 4, May 2, June 6, July 4, and Aug. 1.

During an emergency, the sirens are used to alert residents to potential danger from a flood or other immediate threat. Siren tests ensure that all systems and procedures are working properly during the season of peak flood danger. The tests also promote public awareness of the warning sirens located throughout Boulder County.

There are more than 30 outdoor warning sirens in place across Boulder County, including in Boulder, Erie, Jamestown, Lafayette, Longmont, Louisville, Lyons, Marshall, Eldorado Springs and the University of Colorado at Boulder. The monthly siren tests will be issued from all locations other than Longmont (which follows a different schedule) and Louisville (which does not do audible testing).

Should Boulder County experience severe weather during a one of the planned audible tests, the siren tests for that day may be cancelled. For updated information, visit www.BoulderOEM.com.
