Flagstaff, Arizona – Heavy rain moving across northern Arizona could trigger flash flooding through Wednesday afternoon, especially in burn scar areas, creeks, and popular canyons near Sedona and Flagstaff.
According to the National Weather Service in Tucson, a Flood Watch is now in effect for Coconino and Yavapai counties, including the Grand Canyon, Oak Creek, Mogollon Rim, and surrounding high terrain. The watch began at 11 a.m. Tuesday and extends through 5 p.m. Wednesday.
Flash floods are most likely in slot canyons, dry washes, and areas recently impacted by wildfires. Roads like Highway 89A near Sedona and I-17 near Cordes Junction could see dangerous low-water crossings. “Training thunderstorms” — repeated storms over the same area — could lead to rapid runoff and deadly currents in side canyons.
Officials urge residents and visitors to stay alert for flash flood warnings, avoid driving through flooded roads, and keep out of narrow canyons. Hikers in popular areas like Oak Creek Canyon and West Fork Trail should plan alternate activities.
Rainfall intensity may ease by late Wednesday, but more flood watches may follow if storms persist into Thursday.
