Integrated Public Alert and Warning System
The Integrated Public Alert & Warning System (IPAWS) is a national system for local alerting that provides authenticated emergency alert and life-saving information messaging to the public through mobile phones using Wireless Emergency Alerts (WEA), and to radio and television via the Emergency Alert System.
WEAs are short emergency messages from authorized federal, state, local, tribal and territorial public alerting authorities that can be broadcast from cell towers to any WEA‐enabled mobile device in a locally targeted area. Wireless providers primarily use cell broadcast technology for WEA message delivery. WEA is a partnership among FEMA, the Federal Communications Commission (FCC) and wireless providers to enhance public safety.
WEAs can be sent to your mobile device when you may be in harm’s way, without the need to download an app or subscribe to a service. WEAs are messages that warn the public of an impending natural or human-made disaster. The messages are short and can provide immediate, life-saving information.
