FLAGSTAFF, Ariz. – A widespread flood watch is in effect across northern and central Arizona this morning, as heavy rain from deep subtropical moisture continues to drench the region. The National Weather Service in Flagstaff warns that flash flooding could make travel along I-40 and rural mountain routes dangerous through Saturday evening.
According to the National Weather Service, the Flood Watch covers much of Coconino and Yavapai counties, extending east toward the Mogollon Rim and north toward the Grand Canyon. Repeated downpours could send creeks and washes over their banks, with fast-moving runoff flooding low-lying roads, campgrounds, and hiking areas. Residents are urged to avoid crossing flooded roadways, charge devices in case of power interruptions, and stay alert for rapidly changing conditions.
Flagstaff Police and ADOT officials report that unpaved roads may become muddy and impassable, especially near Sedona, Williams, and the Oak Creek Canyon corridor. Hikers and campers should move to higher ground and avoid narrow canyons where flash floods can strike with little warning. Rainfall totals may exceed two inches in some mountain zones by Saturday night before tapering off Sunday.
By late Sunday, cooler air filters in from the west, ushering in drier fall conditions into early next week. Temperatures will rebound slowly, with clearer skies favoring leaf-peeping and fall events as the region dries out.
