Flash Flood Carries Bighorn Fire Debris Along Channel Outside Tucson

Authorities in Pima County are warning of increased flash flood risk in the wake of the Bighorn Fire, and they showed just what they mean with a video taken July 15 showing floodwater carrying charred debris along a channel outside Tucson.

The county said the Bighorn Fire had left “the ground charred, barren, and unable to absorb water.” This meant that “even a light rain can produce devastating flash flood and mudflows, often with little warning.”

By July 15, the Bighorn Fire was reported to have burned 119,541 acres, and was 89 percent contained. Credit: Pima County via Storyful
