Big Rock TN flooding

A major severe thunderstorm and flash flood event affected Middle Tennessee from Wednesday, July 6, 2016 into Thursday, July 7, 2016. Three rounds of thunderstorms called Mesoscale Convective Systems (MCS) moved across the area over these two days, with the first MCS occurring on Wednesday afternoon July 6, the second MCS from Wednesday night into Thursday morning July 6-7, and the third MCS during the afternoon of July 7.  The first MCS produced several reports of wind damage across northern parts of Middle Tennessee, while the second MCS produced scattered wind damage and dropped 3" to 8" of rain, which caused major flash flooding over northern Middle Tennessee. The final MCS on Thursday afternoon July 7 brought  another round of more widespread wind damage.

Based on reports from the Tennessee Emergency Management Agency and local media, the flash flooding damaged or destroyed over 65 homes, businesses, and other buildings across Stewart, Montgomery, Robertson, Sumner, and Cheatham Counties, as well as washed out numerous roads and bridges. Amazingly, no injuries or fatalities were reported despite the widespread damage.
