Residents across a broad stretch of the Central Coast heard emergency sirens sound for six minutes around midday Saturday. It was part of the San Luis Obispo County Early Warning System test, which the county reported was successfully completed.
During each of two three-minute tests, all 131 sirens operated successfully, the county said. Sirens are situated in the county’s Emergency Planning Zone, which stretches from Cayucos south to the northern Nipomo Mesa and east through San Luis Obispo. The sirens serve as a public alert system that can be activated in case of an emergency.
The county’s Reverse 911 system was tested in conjunction with the siren tests for the first time this year.
The system alerts residents and businesses within the Emergency Planning Zone of an emergency. It includes landline phones, but owners of cellphones and Web-based phone services must register to be included in the system.
