The Wireless Emergency Alert system is used to notify Americans about risky weather from the National Weather Service, AMBER Alerts for missing children, and other urgent situations from federal, state and local authorities. That test will assess the effectiveness of sending out "a national message and determine whether improvements are needed".
A "Presidential Alert" sent to wireless phones and across the EAS would be issued in the event of an actual national emergency, such as a declaration of war or coordinated terrorist attacks, as determined by the president or the president's designee.
While the Emergency Alert System has been tested before, the Wednesday test will be the first time the nationwide Wireless Emergency Alert system will be tested. It would also allow most users to receive location-targeted notifications of "imminent threats to safety in their area", officials furthered.
Get ready for a lot of simultaneous phones going off at the office tomorrow afternoon.
