BOULDER, Colo. - Residents and workers across Boulder County should listen for a siren test on Monday at 10 a.m. and 7 p.m.
There are more than 30 outdoor warning sirens across Boulder County, including in Boulder, Erie, Jamestown, Lafayette, Longmont, Louisville, Lyons, Marshall, Eldorado Springs and the University of Colorado at Boulder.
The audible siren will be tested at all locations except Longmont (which follows a different schedule) and Louisville (which does not do audible testing), according to the Boulder Office of Emergency Management.
The sirens are used to alert residents of dangerous situations such as flooding and tornadoes.
Boulder County plans to test the sirens on the first Monday of the month from April through August.
