Published: July 11, 2026
Residents in Cocke County and Greene County, Tennessee, are under a Flash Flood Warning as periods of heavy rainfall continue to move across East Tennessee. The warning comes as slow-moving thunderstorms produce intense rainfall capable of causing rapid flooding in low-lying areas, small streams, creeks, and roadways. Recent rounds of heavy rain have already saturated the ground across the region, increasing the likelihood of dangerous runoff and flash flooding.
Why the Flood Threat Is Increasing
The National Weather Service indicates that repeated thunderstorms moving over the same locations are creating ideal conditions for flash flooding. Saturated soils can no longer absorb additional rainfall efficiently, allowing water to rise quickly in creeks, drainage ditches, and flood-prone roads. A Flood Watch also remains in effect across much of East Tennessee through the weekend, signaling the potential for additional warnings as storms continue.
Areas Most at Risk
The greatest flooding concerns include:
- Cocke County
- Greene County
- Small creeks and streams
- Rural roads
- Low-water crossings
- Urban areas with poor drainage
- Valleys near the Appalachian foothills
Motorists should expect rapidly changing road conditions, especially where water may cover pavement without warning.
Recent Flooding Across East Tennessee
East Tennessee has experienced multiple flooding events in recent weeks. Emergency crews have responded to flood-related incidents in Greene County, including evacuations at recreational areas after heavy overnight rainfall. These recent events demonstrate how quickly localized flooding can develop, even after storms begin to weaken.
Flash Flood Safety Tips
If you live in or are traveling through Cocke or Greene counties:
- Never drive across flooded roadways.
- Move immediately to higher ground if water begins rising.
- Stay away from creeks, streams, and drainage channels.
- Keep multiple ways to receive emergency weather alerts.
- Delay unnecessary travel until the warning expires.
Remember the National Weather Service’s message: Turn Around, Don’t Drown.
Stay Weather Aware
Additional showers and thunderstorms remain possible through the weekend, meaning flood conditions may worsen or expand into neighboring communities. Residents should continue monitoring forecasts and be prepared to act quickly if additional Flash Flood Warnings are issued.
