The monthly test of the 蘑菇视频 outdoor warning sirens will be Saturday, June 4, immediately following the monthly test of the Metro sirens at noon.
The Metro sirens are tested on the first Saturday of each month. The 蘑菇视频 sirens are tested immediately following the test of the Davidson County sirens to allow individuals to be able to hear and distinguish the Metro sirens from the 蘑菇视频 sirens by both location and distinctive alert tone.
During tests, the sirens typically sound for only 15-30 seconds; during an actual alert, the sirens sound for three minutes.
The test of the 蘑菇视频 siren system is preceded by an announcement stating, 鈥淭his is a test of the 蘑菇视频 severe weather sirens. This is ONLY a test.鈥� Because voice announcements do not carry as far as the siren wail, the announcement may not be audible in all locations prior to the test.
