Test messages will be sent to all TVs, radios and mobile phones

Get ready for a lot of simultaneously buzzing phones on Oct. 4.

There is going to be a nationwide test of the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA) that day.

FEMA is coordinating with the Federal Communications Commission to carry out the test at approximately 2:20 p.m. ET on Wednesday, Oct. 4.

It will be split into two portions.

The WEA portion of the test will be directed to all consumer cell phones. This will be the third nationwide test, but the second test to all cellular devices. The test message will display in either English or in Spanish, depending on the language settings of the wireless handset.
