Flooding remains a major concern:

NashSevereWx reports: “Already 2″ to 3″ has fallen, much more incoming. Main concern for the worst flooding is south of I-40, and especially cutting through Will Co. Nashville will see less rain by comparison, but it also doesn’t drain as efficiently. Concern rising for flash flooding tonight.”

A Flash Flood Watch remains in effect until 7 AM Sunday.

More Storms Expected This Evening

Timing for the most intense storms is roughly 9PM-2AM. This could change with newer data, per NashSevereWx

Tornado Watch South of Rutherford County

NWS issued a Tornado Watch until 9pm for parts of Alabama, Arkansas, Mississippi and Tennessee until 9 PM; however, NWS says if you live north of the watch this does not mean you are in the clear. Keep monitoring because we may need to include you in an additional watch later this evening. The threat may struggle to reach as far north as Clarksville, but we still can’t rule out a severe weather threat that far north later tonight.

Multiple rounds of storms are expected on Saturday. The first round is moving across middle Tennessee this morning with a torrential downpour, hail, thunder and lightning.

Severe Thunderstorm Warning including Franklin TN, Smyrna TN, La Vergne TN in effect until 8:45 AM CDT

Biggest threats (from NWS): heavy rainfall leading to flash flooding, so if you live in a flood prone area keep this in mind! Also remember that if you encounter flooded roads – Turn Around, Don’t Drown! However, these storms will also pose a risk for a few tornadoes, thunderstorm wind gusts up to 75 mph, and large hail. Know where your safe place and shelter is located in case a warning is issued for your home today or tonight!
