METRO TORNADO WARNING SIREN SYSTEM
BETTER, BIGGER, BROADER

New sirensMetro’s Tornado Warning System began with a federal grant in 2002, and is now becoming better, bigger and broader. Between late February and the end of April, 20 new sites will be added, going from 73 to 93 locations countywide. Each siren is located in public gathering places selected by city planners on the basis of outdoor population and population density.

Funded with $2 million in local capital improvement dollars recommended by Mayor Karl Dean and approved by the Metro Council, the entire system will also be upgraded with new siren equipment that will emit an easier-to-hear warning signal, which is more like an old air-raid warning rather than the mechanical tone presently in use. The expanded, upgraded system will make the coverage area bigger and broader across Davidson County.

The Tornado Warning Siren system is to help those in outdoor areas be aware that a tornado warning has been issued for any portion of the county.  A Tornado Warning means a tornado may have been indicated on Doppler radar or a trained spotter has spotted a funnel cloud or tornado in progress. With the approach of the spring tornado season, the entire system will remain ready at all times for use if needed, with both signals being used during the construction and upgrade period.
 
This web page provides the information you need about how the system works, a map of current and new siren locations and how the new siren signal (and the old one) sounds. All sirens are tested at noon on the first Saturday of each month and silently tested daily internally by the system itself. Other than tests, the sirens are only activated by the Mayor’s Office of Emergency Management in the event the National Weather Service issues a Tornado Warning for any portion of Davidson County.

When the sirens are activated:

  • Go inside a sturdy building to the lowest level,away from exterior walls Stay away from windows
  • Cover your head
  • If there is no building available, and the storm is on top of you, find a ditch or low-lying area
  • Lay down and cover your head
  • Wait until the storm passes, then go safely
