Flagstaff, Arizona – Residents and drivers in northern Arizona should be prepared for potentially hazardous conditions on I-40 by Monday morning, as thunderstorms are expected to sweep through Flagstaff and surrounding areas. Heavy rainfall, lightning, and the risk of local flooding could create dangerous travel situations, prompting officials to advise against unnecessary driving and to secure any outdoor items before the storm hits.
The National Weather Service in Flagstaff has indicated that there’s a 60-80% possibility of storms from Monday through Wednesday. The most intense weather is anticipated on Monday morning and Tuesday afternoon, with showers likely to persist into Wednesday evening. Flash flooding is particularly concerning for low-lying and recently burned areas.
Traffic in downtown Flagstaff and on key routes like I-17 and I-40 might slow due to water pooling and reduced visibility. Outdoor activities throughout Coconino County could also be disrupted by frequent lightning and unexpected downpours. Travelers are encouraged to check road conditions beforehand and to plan for extra travel time.
While conditions may improve a bit by Thursday, with drier and warmer weather returning, isolated storms could still pop up every afternoon. Residents are advised to stay updated, especially those living in flood-prone regions.
