Emergency Preparedness - Wireless Alerts
Federal Emergency Management Agency
In the wake of recent natural and man-made disasters, it is now more important than ever to encourage, educate, and empower Americans to identify Wireless Emergency Alerts (WEAs) so that they can be better prepared when disaster strikes.
WEAs are emergency messages sent by local authorized government authorities through wireless carriers’ networks. The alerts include a unique sound and vibration, are no more than 90 characters, and instruct specific actions individuals should take. Types of alerts include extreme weather such as hurricane, tornado or flash flood warnings; AMBER alerts and alerts issued by the President. More than 100 carriers, including all of America’s largest wireless carriers, offer the WEA service for free and no subscription is necessary. Alerts are broadcast from area cell towers warning everyone in range with a WEA-capable device of a potential emergency situation.
