On Wednesday, October 3, 2018 at 11:18 a.m., the Federal Communications Commission (FCC) will issue a Wireless Emergency Alert (WEA) message. The message will be sent to all cell phones in the United States in coordination with a nationwide test of the Emergency Alert System (EAS), which will be broadcasted over radio and television station providers. The message will note "THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed."
The WEA is a public safety system that allows wireless phones and other enabled mobile devices to receive geographically-targeted alerts in the form of text messages. The most common use of the program in Southern California is the Amber Alerts program.
