Flash Floods in Grand Canyon Leave About 15 Missing and 62 Evacuated

About 15 people believed to be missing were being sought Sunday after flash floods swept through parts of Arizona’s Grand Canyon, while park officials evacuated dozens of visitors from affected areas.

At least 62 people had been evacuated by early Sunday. The National Park Service said staff were working with the Arizona Department of Public Safety to continue evacuations and locate anyone who may have been in the flooded zones. Authorities asked people with information about hikers in the affected areas to contact park officials.

The flooding caused extensive damage in the Bright Angel corridor. Nearly all pedestrian walkways crossing Bright Angel Creek were destroyed, cutting off foot access across the creek. Access to the Colorado River in the area, along with several bridges, will remain closed until further notice. Officials did not provide a reopening date.

Park staff, in coordination with the Arizona Department of Public Safety, continue evacuation and response efforts and are working to locate people who may have been in the affected area.

More evacuations from several campgrounds were expected because forecasts called for additional thunderstorms and heavy rain on Sunday and Monday. Authorities warned that the weather could trigger more flash floods, debris flows and rockfalls, while rapidly changing conditions could affect trails and the river. The National Park Service said no injuries had been reported in its latest update.

The Grand Canyon ranked fourth among the most visited U.S. national parks, recording 4,430,653 recreational visits in 2025. Storms also affected other parts of the country over the weekend. In San Antonio, Texas, more than 200,000 people remained without power after storms hit the area from Friday, and two deaths were believed to be linked to flooding.
