SIRENS
San Luis Obispo County's Early Warning System Sirens would sound to alert area residents and visitors to tune to a local radio or television station for information. The sirens alert you that an emergency is taking place within the County and possibly at Diablo Canyon Power Plant. There are over one hundred sirens located in Protective Action Zones 1 through 12 which make up the Early Warning System.

Residents may also be alerted by sirens and loud speakers used by police and fire agencies.

LOCAL RADIO AND TELEVISION
The Emergency Alert System (EAS) is used to inform you about the nature of the emergency and what steps you should take. All local radio and television stations are part of the Emergency Alert System and will broadcast and repeat official information about major emergencies.

The primary EAS radio stations in this area are: 920 AM, 1400 AM and 98.1 FM. If at sea, Marine Channel 16 will carry emergency information.
