The first scheduled nationwide test of the federal Emergency Alert System will occur Wednesday at 11 a.m. PST. Anyone watching television or listening to the radio should hear the alert, which is expected to last up to 31/2 minutes, according to a news release from the Columbia County Sheriff's Office. The Washington State Patrol issued a plea today that residents refrain from calling 911 to ask about the test.
The test will be broadcast over all radio and television stations, cable television, satellite radio and television services and wireline video service providers across all states and territories of Puerto Rico, the U.S. Virgin Islands and American Samoa simultaneously.
The alert system is under the auspices of the U.S. Department of Homeland Security's Federal Emergency Management Agency and the Federal Communications Commission.
