Flagstaff, Arizona – A sharp cold front will sweep across northern Arizona late Thursday morning, triggering wind gusts up to 45 to 50 mph that could make travel hazardous along Interstate 40 and U.S. 89 through sunset.
According to the National Weather Service in Flagstaff, temperatures will drop 10 to 15 degrees behind the front as strong southwest winds develop, especially across east-central Arizona. A Wind Advisory is in effect for parts of northern Arizona, where peak gusts could exceed 45 mph during the afternoon hours.
The strongest winds are expected from Flagstaff east toward Winslow and south along I-17 toward Camp Verde. High-profile vehicles on I-40 may encounter sudden crosswinds, particularly in open stretches east of Flagstaff. Areas of blowing dust could briefly reduce visibility near construction zones and exposed terrain.
Afternoon highs will trend noticeably cooler compared to recent days, with communities across the Mogollon Rim and White Mountains seeing a brisk shift by midafternoon. A slight chance of light snow showers is possible in far northern Arizona, though widespread accumulation is not expected.
Residents should secure loose outdoor objects and avoid outdoor burning as gusty winds increase fire spread potential. Drivers are urged to keep both hands on the wheel and allow extra stopping distance.
Winds will gradually diminish after sunset Thursday, but additional advisories may be issued if gusts exceed current projections.
