Monthly emergency warning siren testing to begin May 2

After a one-month delay due to community impacts from Boulder county’s recent wildfires, the Boulder Office of Emergency Management will begin audible emergency warning siren testing on Monday, May 2, at 10 a.m. and 7 p.m. 

Tests are conducted on the first Monday of each month from April through August. Planned tests may be canceled during severe weather events.

Siren tests ensure all systems and procedures are working properly during peak flood season and are meant to be audible throughout Boulder County. 

CU Boulder community members may hear the siren tests from many locations on main campus. The audible sirens are designed to reach people who are outdoors, not indoors. 

The tests are also a good reminder to sign up for alerts for both on-campus and off-campus emergencies. Information on CU Boulder Alerts can be found here, including user sign-up, how to find information in an emergency and the Guardian mobile safety app. 

For off-campus incidents, all students, faculty and staff are highly encouraged to sign up for Everbridge to be notified of emergencies in the city of Boulder or Boulder County.
