At least 20 people may be missing after a flash flood struck Grand Canyon National Park in Arizona on Saturday, according to a statement from Grand Canyon National Park.
The US National Park Service (NPS) put out a statement on Sunday, asking the public to provide any information about the unaccounted for individuals following "a significant flash flood event in Bright Angel Canyon and the Phantom Ranch area."
"Grand Canyon National Park staff, in coordination with the Arizona Department of Public Safety, are continuing evacuation and response efforts and working to account for individuals who may have been in the affected area," the statement read.
On Sunday, 62 people have been evacuated from the affected areas of the National Park, with additional evacuations scheduled throughout the day. No injuries have been reported.
Debris due to flash flood has closed Colorado River
"The flash flood resulted in significant impacts to infrastructure throughout Bright Angel Canyon. Nearly all footbridges spanning Bright Angel Creek were destroyed, eliminating hiker access across the creek."
NPS added that debris and metal structures entered the Colorado River following the flash flood, leading to the river being "closed to river traffic until further notice."
"Additional thunderstorms and heavy rainfall are possible Sunday and Monday, which could result in additional flash flooding, debris flows, rockfall, and changing trail and river conditions."
This is a developing story.
