Your electronic devices may alarm you today — 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.
The test will occur simultaneously across time zones, so people in the middle of the country can expect it at 1:20 p.m. Central Time, or 12:20 p.m. Mountain Time. On the West Coast it will be at 11:20 a.m. Pacific Time. In most of Alaska it's at 10:20 a.m., and in Hawaii, 8:20 a.m. local time.
Most Americans with wireless cellular devices will receive an emergency alert message on their phones, as will most whose televisions or radios are on when the test occurs.
