City and county agencies in Boulder will test outdoor emergency warning sirens next Monday at 10 a.m.

The tests are conducted annually on the first Monday of each month from April through August to ensure that all systems and procedures are working properly during the season of peak flood danger.

Siren tests will take place on April 2; April 23 (in conjunction with a flood tabletop exercise for staff); May 7; June 4; July 2; and August 6.
