The U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA), in coordination with the Federal Communications Commission (FCC), will conduct a nationwide test of the Wireless Emergency Alert System (WEA) and Emergency Alert System (EAS) tomorrow, August 11 at approximately 2:20 PM.

The WEA system is used to warn the public about dangerous weather, missing children, and other critical situations through alerts on cell phones. The EAS system is also used in major emergencies to broadcast emergency information via radio and television.

New This Year: Only cell phones that have enabled the WEA test setting and are powered on will receive the test alert. Cell phones should only receive the message once.

For instructions on how to enable the WEA test setting, please visit: WEA Test Opt-In Instructions.
