Regions impacted include Jacob Lake, Page, Supai, and portions of Grand Canyon National Park, where drainages like Bright Angel Creek, Kwagunt Creek, and Crystal Creek face a high risk of rapid debris flow.
Visitors and locals are advised to avoid flood-prone zones such as slot canyons, washes, and creek crossings, especially near the Bright Angel Trail and Phantom Ranch, according to the National Weather Service Flagstaff.
Safety Precautions
- Hikers, rafters, and travelers should avoid low-lying trails and canyons.
- Be aware that sediment and debris could rapidly funnel through typically dry areas downstream of burn scars.
