Flash floods in the Grand Canyon last weekend left two dead and one still missing, authorities said Monday.

A supercell storm hit the Bright Angel Creek area, popular with hikers and river rafters, Saturday afternoon. Searchers used helicopters, night vision and other equipment to help tourists evacuate, Cmdr. Dave Black said. 45 people were rescued Saturday evening and 37 more were reduced Sunday.

Only two deaths related to the flash floods have been reported; John Giusti, a Texas chiropractor and Brent Rosencrantz, owner of a martial arts studio in Granbury, Texas. Giusti and Rosencrantz had been camping together in the Bright Angle Creek area along with their friend Timothy Allen Smith who, as of Monday night, was still reported missing.

The flash floods also damaged the only water pipeline in the Grand Canyon National Park. Year-round residents have been placed on water restrictions and lodges and hotels have been closed until the pipeline can be fixed.

Native tribes of the Grand Canyon like the Havasupai Tribe, the People of the Blue Green Water were not heavily affected by the recent flash floods. In 2024, floods in the Grand Canyon killed one Havasupai woman and led to 100 others being airlifted out.

A study posted in the journal Weather and Climate Extremes found short-term intense downpours in the west, like the recent flash floods, have strengthened by 10% since 2000.

More flash floods and thunderstorms are expected before the end of the Grand Canyon’s monsoon season in mid-September.

Phantom Ranch, Bright Angel Campground, Phantom Ranch Canteen, the North Kaibab Trail, the Black and Silver Bridges and traffic to the Colorado River near the affected areas will be closed until further notice.
