A daily total of 160 mm (6.4 inches) of rain was recorded at Chattanooga Metropolitan Airport (Lovell Field) on August 12, making it the second-wettest day on record for the city since records began in 1879, according to the U.S. National Weather Service (NWS) Morristown.
The intense rainfall was associated with slow-moving, moisture-laden thunderstorms that trained over the region for several hours. Localized rainfall rates exceeded 50 mm (2 inches) per hour, rapidly overwhelming urban drainage systems and low-lying areas.
Flash flooding began affecting the Chattanooga metropolitan area by late evening, leading Hamilton County Mayor Weston Wamp to declare a local state of emergency. Hamilton County Schools were closed on August 13 as a precaution.
At least three people have died after torrential rain caused flash flooding in Chattanooga, Tennessee, on Tuesday.

Floodwaters forced the closure of Interstate 24 near McBrien Road in East Ridge, where Tennessee Department of Transportation cameras captured officers assisting stranded motorists. The interstate reopened later after water levels receded.
Hydrological data from the NWS indicated that South Chickamauga Creek at Chickamauga Creek Road reached approximately 5.21 m (17.1 feet) at 09:15 local time (LT) on August 13. Minor flood stage for the gauge is 5.49 m (18 feet).
The NWS issued a Flood Watch for portions of Middle and East Tennessee through Wednesday night, warning of additional rainfall on saturated ground.
Officials advised the public to avoid driving or walking through floodwaters, emphasizing that even shallow moving water can be life-threatening.
