Flash Flood — Sequatchie, TN

Sep 27, 2024

Tropical Storm Helene caps off a several day heavy rainfall event in association with a stalled closed upper low that drew a stream of tropical moisture into the area on the 25th and 26th. The arrival of Helene on the 27th yielded catastrophic flash flooding and river flooding, as well as significant wind damage as wet soils and strong wind gusts led to forest damage.
