NASHVILLE, Tenn. (WTVF) — Starting this week, upgrades to the Davidson County's tornado warning system will begin.

During this phase of the project, 20 new tornado warning sirens will be added around the area.

For each installation, crews will install the siren, and then conduct a growl test to ensure success. You may hear these tests around the county in the coming weeks as installations are completed. Tests will only be completed Monday through Friday, provided the weather is clear. Multiple tests per site, lasting around 15 seconds each, is expected.

The 20 new sirens will expand the coverage of tornado sirens into more rural areas of Nashville. This will bring the total number of sirens to 113.

The upgrades will be installed by Federal Signal and Commtech Radio, in conjunction with Metro Information Technology Services and the Metro Office of Emergency Management.

The new upgrades, when complete, will include a polygonal alerting tornado siren system. With this system, weather warnings are issued to potentially impacted areas based on observed track and speed of the storms, as opposed to the entire county.
