Outdoor Early Warning System
The outdoor
early warning system consists of 70
sirens placed in public gathering places throughout the city to
warn people outside of a tornado warning that has been issued in Davidson
County. These sirens are tested at noon on the first Saturday of each
month, and silently tested daily.
When the National Weather Service issues a tornado warning for Davidson County, Doppler radar is indicating that a tornado may touch down or has touched down in the area. Once a tornado warning has been issued, the Mayor's Office of Emergency Management will activate all 70 sirens in the outdoor early warning system. The high-pitched siren will sound continuously for a full three minutes and will repeat in eight minute intervals for the duration of the warning period. For example, during a 15-minute warning period, the sirens will sound twice. The sirens will be activated for the initial warning and again during the eighth minute of the warning.
