The Emergency Alert System (EAS) is a national public warning system in the United States designed to allow authorized officials to broadcast emergency alerts and warning messages to the public via cable, satellite, or broadcast television, and both AM/FM and satellite radio. The point of the emergency alert is to inform the public of imminent threats to public safety, such as severe weather situations (including flash floods and tornadoes), AMBER Alerts, and other civil emergencies. The EAS is used at a regional scale to distribute information regarding these threats. The system is also used to allow the President of the United States or their designee to deliver a message over the EAS via the Primary Entry Point system during a national emergency within 10 minutes. The EAS is maintained by the Federal Emergency Management Agency (FEMA) and the Federal Communications Commission (FCC) . The FCC establishes performance standards for EAS participants, procedures for participants to follow in the event the system is activated, and testing requirements for the system. The majority of EAS alerts originate from the National Weather Service in response to severe weather events, but an increasing number of alerts are being sent by state, local, territorial, and tribal authorities. The Wireless Emergency Alerts (WEA) system is a different but related system that sends emergency messages directly to mobile devices. The WEA system is also maintained by FEMA and the FCC.
