A nationwide test of the emergency and wireless alert systems will be conducted Wednesday at 2:20 p.m. ET, when a message will be sent to all cellphones, TVs and radios.
The Federal Emergency Management Agency said in a news release in August that a message that reads, “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed,” will be sent to all phones. A Spanish version of the message will be displayed depending on the language settings of the devices.
A separate message will be sent to radios and televisions, saying, "This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency, covering the United States from 14:20 to 14:50 hours ET. This is only a test. No action is required by the public."
