SLO County residents may receive Reverse 911 calls and hear sirens Saturday as part of an annual test of the countys early warning system by the San Luis Obispo County Office of Emergency Services.
Between 9 a.m. and noon on Saturday, Aug. 24, the Reverse 911 system will be activated for landline phones and registered cell phones, according to a news release.
At noon and 12:30 p.m., two full-scale early warning system tests will sound with 131 sirens blaring simultaneously for three to five minutes each in an area spanning the coastal parts of the county from Cayucos to the Nipomo Mesa, as well as San Luis Obispo.
No action is required from the public in response to any of the tests, which are routine.
The sirens were installed as requirements for the Diablo Canyon nuclear power plant, but they can be used for any major emergency to alert large numbers of people to tune in to a local radio or TV station for emergency instructions, the release said.
