San Luis Obispo County will conduct low-volume growl tests of its early-warning systems sirens this week.
On Tuesday and Wednesday morning, each of the 131 sirens located within the Diablo Canyon Emergency Planning Zone will be individually tested for a period of a few seconds.
The San Luis Obispo County Office of Emergency Services announced the siren testing Monday, adding that the alarms are only a test and no action is needed on the part of the public.
The system’s sirens cover an area from Cayucos to the Nipomo Mesa.

In the case of an actual emergency, sounding of the sirens indicates that residents should tune in to a local television or radio station for information on how to proceed.
