Wireless Emergency Alerts (WEA) are
|“||emergency messages sent by authorized government alerting authorities through mobile carriers to their subscribers.||”|
"WEA was established in response to the Warning, Alert, and Response Network Act passed by Congress in 2006. The Federal Communications Commission proposed and adopted the network structure, operational procedures, and technical requirements for WEA in 2007 and 2008, in cooperation with commercial wireless providers. Subsequently, the Department of Homeland Security Science and Technology Directorate and the Federal Emergency Management Agency have worked with the wireless carriers on deployment and testing of the system. The present design supports only 140-character messages and messages that fit into a single cell broadcast."
WEAs looks like a text message. The WEA message will show the type and time of the alert, any action you should take, and the agency issuing the alert. The message will be no more than 90 characters. WEA messages include a special tone and vibration, both repeated twice.
