FLAGSTAFF, Ariz. – Deep tropical moisture continues to drench much of northern Arizona this Saturday morning, sending flash flood concerns across the region just as the long Columbus Day weekend begins. Creeks, washes, and low-lying crossings are filling quickly, and travelers are urged to watch for water-covered roads, especially along I-40 and U.S. 89.
According to the National Weather Service in Flagstaff, a Flood Watch remains in effect through Saturday night as widespread rain and embedded thunderstorms move across the Coconino Plateau, Verde Valley, and Mogollon Rim. The heaviest rainfall is expected through Saturday afternoon before showers gradually taper from west to east late in the day.
By Sunday, conditions begin to ease, but scattered showers could linger into Columbus Day morning, especially east of Flagstaff and near Winslow. Highs will climb back into the 60s by Monday under partly sunny skies, offering a brief break before cooler fall air moves in midweek.
Officials urge residents and visitors to stay alert for road closures and potential debris flows near burn scars and canyon roads. Those planning outdoor activities, pumpkin patch visits, or fall leaf excursions should monitor local alerts and prepare for slick trails and soggy fields.
Drivers are reminded never to cross flooded roadways—“Turn Around, Don’t Drown.” Keep mobile devices charged in case of flash alerts or power outages and avoid travel in flood-prone zones until conditions improve.
