The Emergency Alert System(EAS) is a nationwide emergency alerting program that broadcasters must provide communications capability to the President to address the nation in national emergencies. The Federal Communications Commission (FCC), in conjunction with the Federal Emergency Management Agency (FEMA) and the National Weather Service (NWS), implement EAS at the Federal Level.
EAS is available at the state and local level to allow EAS participants to transmit emergency information such as severe weather warnings or child abduction alerts ("Amber Alerts"). Within California, statewide activation of EAS may be done by the Governor, Director of the Governor's Office of Emergency Services, California Highway Patrol, or the National Weather Service. Local EAS activations are usually delegated to public safety officials or local governments.
At present, the EAS is undergoing changes to modernize and enhance alert and warning delivery to the public. This initiative will bring together existing and new public alert and warning systems and technologies in order to provide authorities at all levels a broader range of message options and communications pathways.
