The Federal Emergency Management Agency, in coordination with the Federal Communications Commission, will conduct a nationwide test of the Emergency Alert System and the Wireless Emergency Alerts system late Thursday morning. The Presidential-level Wireless Emergency Alert test message will be sent to mobile devices at 11:18 am, and to radio and television broadcasters, cable systems and satellite providers at 11:20 am. This will be the first nationwide test of the Presidential-level Wireless Emergency Alert. The results of the test will be used to determine whether improvements are needed to Integrated Public Alert and Warning System. The test is in conjunction with Arizona Preparedness Month, which runs through the end of September.
