Snowstorm Brings Heavy Falls and Avalanche Risk to Western Mountains

The storm is rolling into the western United States, packing up to two feet of snow in high‑elevation areas and throwing strong winds that can create whiteout conditions. The National Weather Service has issued warnings across the Rockies and Pacific Northwest, stressing that the sudden build‑up of snow could trigger avalanches. In southern Montana’s high ranges, forecasters expect 1 to 2 feet of snow above 9, 000 feet and wind gusts up to 55 mph. Travelers in exposed backcountry are cautioned that the situation could become very dangerous, especially as fresh snow piles on existing layers. The Cascades in Oregon and Washington are not spared. Between Marion and Lane counties, the forecast calls for 12 to 22 inches of snow, with winds reaching 45 mph. Highway passes such as Santiam and Willamette could become slick, and officials advise delaying trips until conditions improve.On the east side of Oregon’s Cascades, 6 to 12 inches are expected above 4, 000 feet. Winds may also reach 45 mph, potentially bringing down branches and lowering visibility during heavy snowfall periods. Washington’s western mountains face similar threats, with 8 to 18 inches projected above 2, 500 feet and gusts up to 40 mph. Power outages could happen in isolated spots, and commuters should allow extra travel time during peak hours. In northern Montana and Idaho, snow totals range from 6 to 20 inches at higher elevations. Wind speeds often exceed 50 mph, making travel through passes and national parks particularly hazardous. The storm’s reach extends to Alaska’s western Arctic coast, where wind gusts of 45 mph can create blowing snow even with limited snowfall. Open areas between Point Lay and Point Hope may become difficult to navigate.
