Flagstaff, Arizona – Flash flooding is a growing concern across northern Arizona as a Flood Watch remains in effect Saturday through Monday, with heavy rain expected to target wildfire burn scars and canyon drainages.
According to the National Weather Service in Flagstaff, slow-moving thunderstorms over the Kaibab Plateau could dump enough rainfall to trigger flash flooding, especially in areas burned by the Dragon Bravo and White Sage wildfires. Impacted zones include Jacob Lake, Page, Supai, and portions of Grand Canyon National Park, where drainages like Bright Angel Creek, Kwagunt Creek, and Crystal Creek face high debris flow risk.
Travelers, hikers, and rafting groups should avoid flood-prone areas such as slot canyons, washes, and creek crossings—particularly near the Bright Angel Trail and Phantom Ranch. Officials warn that sediment and debris could rapidly funnel through areas that don’t typically flood, especially downstream of the Dragon Bravo scar.
Residents and visitors are urged to stay weather aware, avoid low-lying trails and canyons, and have multiple ways to receive alerts. Additional advisories may be issued if monsoon storms intensify.
