More flooding feared at Grand Canyon as storm leaves 15 missing

Forecasters warned of renewed flash flooding in the Grand Canyon as crews searched for about 15 people missing after Saturday’s storm. At least one person died, and dozens of visitors were evacuated from the Bright Angel Canyon and Phantom Ranch area.

The National Weather Service said rain and thunderstorms were expected Monday afternoon. It warned that normally dry washes, creeks, swimming holes and recently burned areas could flood, while powerful currents could surge through side canyons and narrow slot canyons. Low-water crossings could also become impassable.

Flash flooding will be possible in creeks, normally dry washes, swimming holes, and over recently burned areas.

The National Park Service said 62 people had been evacuated by Sunday morning, with further evacuations planned. The body of a 46-year-old man was recovered Sunday evening near Crystal Rapids along the Colorado River in northern Arizona.

Raging killer currents will be possible in side canyons and narrow slot canyons.

The flooding damaged the Transcanyon Waterline, the park’s main water pipeline. The 20-kilometre line carries drinking water and supports fire suppression between Roaring Springs on the North Rim and the South Rim. Officials imposed water restrictions in the park’s most visited area and prohibited wood and charcoal fires.

The storm also destroyed footbridges and blocked crossings over Bright Angel Creek. Overnight accommodation was scheduled to close from Monday. Hikers’ video showed muddy water rushing along trails and beneath footbridges, carrying logs and other debris through swollen waterways.

These measures are crucial for ensuring the safety and sustainability of water resources.
