If you're watching TV or tuning into the radio at 1 p.m. Wednesday, don't be alarmed if you see a message about a nationwide emergency.
FEMA, DHS and FCC will conduct a first-of-its-kind test of the Nationwide Emergency Alert System to broadcast a message to the American public, according to a press release from FEMA and the U.S. Department of Homeland Security; the test will run concurrently across all time zones.
More from the press release:
In the history of the country, nothing like it has been conducted on such a level. ... There have been tests in the past, but not of this magnitude encompassing all regions of the Nation simultaneously. The three-minute test will run concurrently on all radio and TV band stations exceeding the previous messages broadcast, which were anywhere from a 30 second to 1 minute message.
