The wider storm
A weak upper low helped advect near record moisture into Tennessee, where a boundary and classic heavy rain profiles combined to produce extreme rainfall rates over portions of Chattanooga, leading to numerous water rescues, a few evacuations, flooded interstate and local roads, flooded homes, and unfortunately a few fatalities. One fatality occurred in the east Brainerd area after a driver went around police barricades and was swept away in the flood waters. Damage estimates as of September 2025 were at least $1.7 million dollars per emergency management.
