A major flash flood struck the Grand Canyon National Park in Arizona on Saturday afternoon, August 29. The flooding occurred in the Bright Angel Canyon and Phantom Ranch area, sweeping large boulders, metal structures, and other debris into the Colorado River.
Officials reported that more than 20 people may be missing or unaccounted for after the floods overwhelmed a remote area, including a historic lodge near the bottom of the site. As of Sunday morning, the National Park Service and the Arizona Department of Public Safety have evacuated more than 60 people, and helicopter teams have searched the area for those still missing.
No injuries have been reported, though park officials have warned people against accessing closed areas. National Weather Service meteorologist Justin Johndrow stated that most of the water ran off instantly. The National Park Service further warned of additional thunderstorms and heavy rainfall that could trigger more flash flooding.
Starting Monday, tourists will be unable to stay overnight at lodges and hotels within Grand Canyon National Park.
