PREVIOUS STORY: FEMA announced Monday that the "Presidental Alert" test has been moved to October 3 due to ongoing Hurricane Florence response. The alert will not interrupt a phone call or an active data session, though FEMA and the FTC are working to make sure the information reaches more people. "Does this mean I'm going to get whatever message President Trump wants to send out through this alert system now?'" Werner said.

It's just a test, but don't try to opt out of receiving it - there's no way to stop the alert from popping up on your phone or television screen. The presidential alert is nationwide and will only be used to warn of an impending national crisis.
The Federal Emergency Management Agency says it'll sound like an Amber Alert or flood warning. If this had been an actual emergency an official message would have followed the tone alert you heard at the start of this message. (Pacific Time), the test involves an alert message sent to all wireless devices, while broadcasting to radio and television. Wireless phones should receive the message only once. Others will not. No action is required.
