On Tuesday and Wednesday, January 20 and 21, the Early Warning System sirens located in the Diablo Canyon Emergency Planning Zone (EPZ) will  undergo regularly-scheduled low-volume growl tests.

Each siren throughout the EPZ will be  tested individually for a period of a few seconds. This is only a test, and no action is required on the part of the public. These tests help emergency officials ensure the siren system is  working properly, should the system be needed during an emergency.  

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. During an emergency, 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 and  instructions.  

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

Should an emergency occur, the sirens are only one of the systems that may be used to alert  and notify the public. For more information on alert and notification systems, visit https://www.prepareslo.org. 

Questions regarding the tests can be answered by the County Office of Emergency Services by  calling (805) 781-5678.
