Boise, Idaho – Strong crosswinds and accumulating mountain snow could make travel hazardous across Idaho beginning Thursday, Feb. 26, as a volatile late-winter pattern builds through Monday, March 2.
According to NOAA’s 6- to 10-day outlook issued Friday, above-normal temperatures are favored across much of the West, while active Pacific systems increase precipitation chances in the Northwest and Northern Rockies during the Thursday-to-Monday stretch. That setup supports gusty winds across southern Idaho and periods of snow in higher elevations.
Statewide, the strongest wind impacts may develop across the Snake River Plain. Boise, Twin Falls and areas along I-84 could see gusts between 55 and 65 mph, creating dangerous crosswinds for high-profile vehicles. Blowing dust is also possible in open rural areas if soils dry between systems.
In eastern Idaho, including Idaho Falls and Pocatello along I-15, fluctuating temperatures may bring a mix of rain and snow at lower elevations, with accumulating snow more likely in the surrounding high terrain. Mountain passes, including Lookout Pass along the Montana border and sections of US-95 in the Panhandle, could see periods of heavier snow that reduce visibility.
Residents should secure loose outdoor equipment, prepare for isolated power outages and check Idaho 511 road conditions before traveling. The unsettled and windy pattern continues through March 2, and additional wind or winter weather advisories may be issued statewide.
