Early Warning System Sirens Undergo Growl Tests

Again today  the Early Warning System sirens located in the San Luis Obispo County Emergency Planning Zone (EPZ) will undergo regularly scheduled low volume growl tests. Each of the 131 sirens throughout the EPZ will be tested individually for a period of a few seconds. This is only a test and no action is requested or required on the part of the public.

Although the Early Warning System sirens were installed and are maintained as one of the requirements related to the operation of the Diablo Canyon Power Plant, the sirens can be used for any local emergency where there is a need for the public to take action. This may include tsunami, dam failure, or other natural or man-made disaster. The sounding of the sirens is an indication that the Emergency Alert System has been activated and the public should tune to a local television or radio station for emergency information.

The Early Warning System sirens cover an area extending from Cayucos to the North to the Nipomo Mesa area to the South. This includes the northern Nipomo Mesa, the Five Cities Area, Avila Bay, See Canyon and Squire Canyon areas, Price Canyon area, Baywood Park/Los Osos, City of San Luis Obispo, Morro Bay and Cayucos areas.
