Flagstaff, Ariz. — Drivers in northern Arizona could face dangerous crosswinds along I-40 on Tuesday as gusts near 33 mph sweep Flagstaff. The blustery stretch arrives with otherwise clear skies, leaving dry conditions that could elevate fire danger and complicate travel.
According to the National Weather Service in Flagstaff, winds will build through Tuesday afternoon, strengthening from the southwest before easing slightly at night. Sustained winds between 13 and 21 mph are expected, with peak gusts topping 33 mph. Officials caution drivers of high-profile vehicles to use extra care along I-40 and U.S. 89.
The good news: skies stay sunny through midweek with highs in the upper 70s, offering comfortable daytime conditions despite the wind. Overnight lows dip into the upper 40s to low 50s, keeping nights crisp and cool. By Thursday, a slight 10 percent chance of thunderstorms develops, but most of the area should remain dry.
Residents should secure loose outdoor items, avoid open burning, and monitor fire conditions. Strong winds paired with low humidity often increase wildfire risk, especially in Coconino County.
Looking ahead, calmer weather is expected into the weekend with highs holding steady in the mid-70s. Winds will ease by Friday night, making for a more pleasant start to the weekend.
Warnings remain in effect through Tuesday evening, with another advisory possible Thursday if thunderstorms develop.
