Flagstaff, Ariz. – A stormy weekend is ahead for northern Arizona, with showers and thunderstorms expected to develop Saturday afternoon and continue into early next week, raising concerns for flooding in low-lying areas.
According to the National Weather Service in Flagstaff, showers are likely by late Saturday morning, with thunderstorms becoming widespread in the afternoon. Rain chances remain high through Monday, with precipitation probabilities ranging from 60% to 80%. Storms may bring gusty winds up to 18 mph, frequent lightning, and locally heavy downpours.
