How intense rains in the Grand Canyon turned into a deadly disaster

A flash flood tore through the Grand Canyon's Bright Angel Creek area on Saturday, killing at least two people, leaving one unaccounted for, and forcing the rescue of nearly 80 visitors from a landscape known for turning postcard weather into a wall of water within minutes.

Federal researchers had already flagged the danger: a Department of Interior team studying the aftermath of the Dragon Bravo wildfire, which burned nearly 150,000 acres and destroyed the historic Grand Canyon Lodge in July 2025, found runoff risk in that stretch of creek two to eight times higher than normal, with hazardous rockfall expected for at least a year.

Scientists point to a stack of compounding factors: drought-hardened, sparsely vegetated slopes that shed rain instead of absorbing it, and a strengthening El Niño loading the atmosphere with extra moisture over the Southwest. Researchers cited in the report found summer downpours in the US West have grown roughly 10 percent stronger since 2000, part of a broader pattern of climate extremes arriving in combination rather than one at a time.
