FEMA Emergency Alert Test: Nationwide alert set for 11:20 a.m. PT


Don't be caught off guard Wednesday morning if you get an emergency alert on your television, radio or cell phone.

The Federal Emergency Management Agency, FEMA, in coordination with the Federal Communications Commission, FCC, will conduct a nationwide test at 11:20 a.m. PST on Wednesday, August 11.

The tests will consist of two portions – testing the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA).


Officials say test messages will be sent to televisions and radios, along with select cell phones that have opted-in to receive test messages.

"The Wireless Emergency Alert portion of the test will be directed only to consumer cell phones where the subscriber has opted-in to receive test messages," FEMA posted online. "This will be the second nationwide WEA test, but the first nationwide WEA test on a consumer opt-in basis. The test message will display in either English or in Spanish, depending on the language settings of the wireless handset."

This week’s testing will be the sixth test of the nationwide public alert and warning systems and has been planned since June 2020. 


The EAS national test is very similar to regular monthly tests typically originated by state authorities. During the test, radios and televisions across the country may interrupt normal programming to play the EAS test message. The message may be delivered in English or Spanish. The EAS test message is approximately one minute long and the audio will say:

"This is a test of the National Emergency Alert System. This system was developed by broadcast and cable operators in voluntary cooperation with the Federal Emergency Management Agency, the Federal Communications Commission and local authorities to keep you informed in the event of an emergency. If this had been an actual emergency an official message would have followed the tone alert you heard at the start of this message. No action is required."    

The visual message, which will only be displayed on televisions, may vary depending on the station. The message will include, at a minimum, the originator, event, location, valid time period of the message and the time the message was transmitted. For example, the text may read: "A Primary Entry Point system has issued a National Periodic Test for all of the United States beginning at 11:20 AM and ending at 11:50 AM on AUG 11, 2021."

The test message sent to the WEA infrastructure will only be received by specially configured phones and will read:

"THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed."

Only phones that have been opted in specifically to receive system test messages will display the test message, which will be in either English or Spanish, depending on the device’s language settings. Most mobile phones will not display the test message. In contrast, consumers will automatically receive real emergency alerts on compatible phones (even if they do not receive the test message).  Instructions for how to opt-in to receive the test message on mobile devices can be found here.

Correction: An earlier version of this article misstated when the test would take place. It was scheduled for 11:20 a.m., not 11:20 p.m.
