Diablo Canyon early warning sirens to be tested Saturday
The San Luis Obispo County Office of Emergency Services will conduct its annual test of the Diablo Canyon Early Warning System on Saturday.
The siren tests are scheduled at noon, and again at 12:30 p.m. During the testing, all 131 sirens will be activated simultaneously according to the county.
The county's reverse 9-1-1 system will also be tested for all landline and registered cell phones located within the Emergency Planning Zone. That test will take place Saturday morning between 9 a.m. and noon, prior to the siren testing.
