Heavy overnight rain left Greene County sloshing early Thursday, with a Flood Advisory in effect until 8:30 a.m. after runoff spread across the area. Officials warned that minor flooding could develop in low-lying and poor-drainage spots and cautioned that water might cover some roadways for the morning commute.
According to the National Weather Service in Morristown, the advisory was issued at 3:36 a.m. EST and covered Anderson, Campbell, Cocke, Grainger, Greene, Hamblen, Jefferson, Knox, Sevier, and Union counties until 8:30 a.m. Doppler radar showed heavy rain early Thursday that triggered the alert, and forecasters warned that water over roadways was possible across the advisory area.
The Town of Greeneville pushed the alert out on its Town of Greeneville Facebook page, urging residents to steer clear of flooded streets and to use extra caution while driving. Local officials also asked anyone who spots hazardous roadway flooding to report it to emergency services so crews can respond where they are needed most.
Where flooding could occur
The highest risk sits in urban low spots, underpasses, and low-water crossings where runoff can collect quickly. Smaller creeks and roadside ditches can also rise with little warning when the ground is already wet. The National Weather Service flood safety page reminds motorists that just a few inches of moving water can disable a vehicle and urges drivers to never try to cross a flooded roadway.
What to watch next
The advisory was scheduled to expire at 8:30 a.m., but scattered ponding and localized roadway closures could linger into the morning. Residents are encouraged to keep an eye on local media, official social channels, and National Weather Service updates for any changes, and to follow emergency instructions if conditions worsen in their area.
