Today and tomorrow, county emergency officials will be running low-volume growl tests for sirens located throughout the Diablo Canyon emergency planning zone.
This zone includes the Five Cities area, Avila Beach, See Canyon, Price Canyon, Baywood Park, Los Osos, the city of San Luis Obispo and Morro Bay.
Emergency officials remind members of the public that these are only tests, and no action is requested or required from the public.
