An Emergency Alert Test Will Sound On All US Cellphones, TVs and Radios On Wednesday

An anonymous reader quotes a report from CBS News: Your electronic devices may alarm you on Wednesday afternoon - but there's a reason for that. A nationwide test of the federal emergency alert system will be broadcast at approximately 2:20 p.m. EDT to cellphones, televisions and radios across the United States at around the same time. Most Americans with wireless cellular devices will receive an emergency alert message, as will most whose televisions or radios are on when the test occurs. The Federal Emergency Management Agency will conduct Wednesday's test in coordination with the Federal Communications Commission. Emergency alert messages that make up the test are divided into two groups -- the Emergency Alert System (EAS) for radios and televisions, and the Wireless Emergency Alerts (WEA) for wireless phones -- although both are scheduled to happen at once. Wednesday will mark the seventh nationwide test of the Emergency Alert System. Six previous tests were conducted over the years between November 2011 and August 2021. This will be the third nationwide test of wireless alerts, and the second nationwide test transmitted to all cellphones, FEMA said in a statement. As the wireless alert tests are sent out to phones, the Emergency Alert System tests will be sent out to televisions and radios. People can elect not to receive certain emergency alert messages to their cellphones from local authorities, or in some instances, simply decide whether to subscribe or not to a specific set of emergency alerts put out by a particular agency. On the other hand, it is not possible to opt out of the upcoming test of the national wireless alert system. All major wireless providers participate in FEMA's wireless alert system. So, most people whose cellphones are turned on and located within range of an active cell tower during the test should receive a message, the agency said (PDF).
