Heavy Rain August 12, 2025 · Hamilton County, Tennessee
Where the report was made, with tornadoes recorded within 15 miles over the years.
What the National Weather Service wrote
Waterlogged soils caused a large oak tree to fall and crush a car, killing the family of 3 within the vehicle. Calm to near calm winds were observed at the time of the incident off the nearby Chattanooga ASOS.
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.
Began near East Ridge (34.9991, -85.2358).
