Public Alert and Warning Infrastructures
Emergency Alert System (EAS)
The Emergency Alert System (EAS) is a national public warning system that allows the president to address the nation within 10 minutes during a national emergency. State and local authorities may also use the system to deliver important emergency information such as weather information, imminent threats, AMBER alerts and local incident information targeted to specific areas.
- Messages can interrupt radio and television to broadcast emergency alert information.
- Messages cover a large geographic footprint. Emergency message audio/text may be repeated twice, but EAS activation interrupts programming only once, then regular programming continues.
- The EAS is sent through broadcasters, satellite digital audio services, direct broadcast satellite providers, cable television systems, and wireless cable systems.
- The President has sole responsibility for determining when the national-level EAS will be activated. FEMA and the FCC are responsible for national-level tests and exercises.
- The EAS is also used when all other means of alerting the public are unavailable.
Wireless Emergency Alerts (WEA)
The Wireless Emergency Alert (WEA) system delivers critical warnings and public safety information to the public on mobile devices. Participation by wireless service providers is voluntary, but most providers support WEAs. Those providers that participate adhere to technical and operational requirements established by the FCC. WEAs began in 2012 and should already be on your cellular phone or other wireless device.
What are Wireless Emergency Alerts?
- Wireless Emergency Alerts, or WEAs, are free messages sent directly to your cellular phone, warning you about severe weather, AMBER Alerts, and threats to safety in your area.
- WEAs are sent to you by your state and local public safety officials, the National Weather Service, the National Center for Missing and Exploited Children, the U.S. Geological Survey, and the President.
- WEA notifications are designed to get your attention and alert you with a unique sound a vibration.
- WEAs resemble a text message on your cellular phone. They will not interrupt calls in progress.
- WEA messages allow alerts to be sent to cellular phones in a geographically targeted affected area.
- WEAs are one-way alerts to any cell phones in range of the cell towner, which ensures that authorities cannot collect any data from an individual.
- WEAs are not affected by network congestion.
Will I receive WEAs on my cell phone?
- Verify device settings & notifications are correctly selected by visiting mil.wa.gov/alerts. Instructions are listed for both Android an Apple phones.
- All major providers participate in WEA on a voluntary basis. Contact your wireless provider for more information.
- WEA messages can save lives. Do not ignore these messages! WEAs contain basic information so if you receive a WEA, seek additional information from other sources such as radio or TV.
