Northern Arizona faces a heightened risk of flash flooding this weekend as monsoon thunderstorms threaten areas scarred by recent wildfires. The National Weather Service in Flagstaff has issued a Flood Watch through Monday, warning that slow-moving storms could dump heavy rain over vulnerable terrain, especially around canyon drainages and burn scars.
Forecasters say the Kaibab Plateau is a particular concern, where storms could unload enough rainfall to trigger flooding and debris flows. Areas impacted by the Dragon Bravo and White Sage wildfires are at elevated risk, including Jacob Lake, Page, Supai, and sections of Grand Canyon National Park. Drainages such as Bright Angel Creek, Kwagunt Creek, and Crystal Creek could quickly swell with water, sediment, and debris. The Dragon Bravo scar is especially concerning, as intense runoff may funnel downstream into areas that do not typically experience flooding.
The threat is not limited to residents. Travelers, hikers, and rafting groups are also urged to take extra precautions. Officials advise avoiding slot canyons, washes, and low-lying crossings, particularly near the Bright Angel Trail and Phantom Ranch. These popular recreation areas could become dangerous with little warning if heavy rain falls upstream. Rapidly rising water levels, coupled with debris flows, can transform familiar trails into hazardous zones in a matter of minutes.
Emergency managers stress the importance of staying weather aware and having multiple ways to receive alerts. Visitors should carry communication devices, review safety plans, and be prepared to move to higher ground quickly if storms develop. Officials caution that additional advisories and warnings may be issued through the weekend as monsoon activity intensifies.
For residents and tourists alike, the message is clear: even in areas that seem dry, flash flooding remains a serious hazard during the monsoon season, especially when burn scars reduce the land’s ability to absorb water. This weekend, vigilance and caution will be essential for anyone traveling or recreating across northern Arizona’s canyons, trails, and river corridors.
