Boulder County will be testing the countywide audible emergency sirens at 10 a.m. & 7 p.m. on Monday, July 6. The monthly emergency audible siren tests 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 6, May 4, June 1, July 6, and August 3.
Siren tests ensure that all systems and procedures are working properly during the season of peak flood danger and is no way related to COVID-19. The tests also promote public awareness of the warning sirens located throughout Boulder County. Sirens are meant to reach people that are outside, not indoors.
The annual siren testing is a good reminder for residents to sign up for emergency alerts at www.BoCo911alert.com. This system allows all community members in Boulder County and all cities within the county to be notified of emergency situations in a variety of ways including cell phone, home and work phones, text message and e-mail.
Should Boulder County experience severe weather during one of the planned audible tests, the siren tests for that day may be cancelled. For updated information, visit www.BoulderOEM.com.
Residents are encouraged to review their own emergency preparedness plans and discuss what they would do in the event of a flash flood or other emergency. For more information about personal preparedness, visit www.ReadyColorado.com.
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 at Boulder.
All Boulder County sirens undergo weekly tests throughout the year, using a software program that performs a “silent” test.
