It is only a TEST... 

MTSU will test its tornado sirens on campus on Wednesday, Nov. 9, at 11:15 a.m. This is only a test of the system, and no safety actions will be required. 

WGNS will be working with the FCC on Wednesday to test the Emergency Alert System at 1:00. All radio and TV stations across the nation are performing the same Emergency Alert Test simultaneously. It will only be a test.
