Flood risks continue in Middle Tennessee today after the first of two rounds of rain moved out overnight, the National Weather Service Nashville said.
The region has seen roughly 1-3 inches of rain so far, with some locally higher amounts, NWS Nashville Meteorologist John Cohen said Wednesday.
Tuesday’s system brought severe storms and triggered a tornado watch. There were also several reports of flooded roadways by the evening, NWS Nashville said.
A flood watch for the region expired at 6 a.m. but is slated to go back into effect at 6 p.m. Wednesday, the NWS reported.
Several rivers are near or at flood stage today, Cohen said. NWS will be keeping a close eye on them today as water continues to runoff continues into creeks, streams and rivers.
On Wednesday, the Cumberland River at the Omohundro Water Plant in Nashville was under a flood advisory until further notice. Other rivers under flood advisories include the Red River at Port Royal until 6 p.m. Friday, affecting Robertson County and Montgomery County; and the Piney River near Vernon until 3 p.m. today, affecting Hickman County.
Parts of the Duck River are experiencing moderate flooding in Perry Countand Dickson County, while parts of the Harpeth River in Dickson and Williamson County are experiencing minor flooding.

It’s important to remain weather aware if you live in a flood-prone area or near a creek, stream, river or other body of water, NWS said.
NWS: More rain expected through Friday morning
While the region will see a break from the rain for most of the day, NWS Nashville Meteorologist Mark Rose said more rain will move in this evening.
Rain will kick off in the northwestern part of the region, including Clarksville, around 7 p.m. and the central part of the region, including Nashville, Columbia and Murfreesboro around 9 p.m. The Cumberland Plateau may not see more rain until after midnight, Rose said.
Another flood watch will likely be issued later today, according to Rose.
The NWS issued an excessive rainfall outlook for Thursday, placing Clarksville and Nashville under a slight risk (level 2 of 4) and the rest of the region under a marginal risk (level 1 of 4).
The forecast shows another 0.5 to 3 inches of rain could fall by Friday morning. Clarksville and Waverly could see up to 3 inches by Friday, while Nashville and parts of Rutherford County could see around 1.5 to 2 inches. Columbia and other areas are expected to get 1 to 1.5 inches.
The already saturated ground and the additional rain will cause streams, creeks and rivers to rise even more throughout the week, Cohen warned. Officials urge people to use extra caution while traveling, especially in flood-prone areas.
“Never cross a flooded road,” the Tennessee Emergency Management Agency tweeted Tuesday. “Turn around, don’t drown!”
Overnight temperatures into Thursday morning may pose a “borderline” risk for freezing rain in the extreme northwestern part of the region, the forecast said. Not much impact is expected.
As always, it’s important to have multiple ways to get weather updates, including cell phone push alerts from local media and weather apps; social media; local news coverage; and NOAA weather radios.
The NWS recommends having an emergency kit you can quickly grab in case of an emergency. It should include essential supplies like food, water, flashlights, batteries, medicine, extra clothing and shoes, toiletries and even solar-powered chargers for electronic devices.
