Flash Flood Warning in Effect for Middle Tennessee
July 22, 2026 – A Flash Flood Warning has been issued for Cannon, Rutherford, and Williamson counties in Tennessee as heavy thunderstorms continue producing excessive rainfall across Middle Tennessee. Rapid flooding of low-lying areas, creeks, streams, and roadways is possible, creating dangerous travel conditions and posing a threat to life and property.
Flash flooding can develop within minutes, especially where repeated rounds of heavy rain occur over already saturated ground. Residents should closely monitor changing weather conditions and be prepared to move to higher ground if flooding develops.
Areas Affected
The Flash Flood Warning includes portions of:
- Cannon County
- Rutherford County
- Williamson County
Communities near rivers, creeks, low-water crossings, and poor drainage areas face the highest flood risk. Floodwaters may also impact urban streets, neighborhoods, and underpasses.
Safety Tips During a Flash Flood Warning
If you are in the warning area:
- Never drive through flooded roadways. Turn Around, Don’t Drown.
- Move immediately to higher ground if flooding begins.
- Stay away from creeks, streams, and drainage ditches.
- Monitor local weather alerts and emergency information.
- Be prepared for rapidly changing conditions, especially after dark when floodwaters are more difficult to see.
Even a small amount of moving water can sweep away a vehicle or knock a person off their feet.
Continue Monitoring Weather Conditions
Additional heavy rainfall may lead to worsening flooding throughout the warning period. Residents of Cannon, Rutherford, and Williamson counties should remain alert for updated warnings and possible road closures as storms continue across Middle Tennessee.
