Jackson, WY – Travel across Wyoming’s mountain passes is becoming increasingly dangerous as heavy snow and powerful wind gusts up to 60 mph create near whiteout conditions through Friday afternoon.
According to the National Weather Service in Cheyenne and Riverton, Winter Storm Warnings remain in effect across much of western and northern Wyoming until 6 p.m. Friday, with widespread snowfall totals between 10 and 20 inches and localized peaks exceeding that . The Sierra Madre and Snowy Range could see up to 20 inches, while the Tetons may reach 24 inches along higher elevations.
Critical travel routes including Teton Pass, Togwotee Pass, South Pass, and Powder River Pass are expected to become snow-packed and hazardous. Winds gusting between 45 and 60 mph will cause blowing snow and sudden drops in visibility, especially above 7,000 feet.
In Yellowstone National Park, snowfall totals vary widely, from 1 to 3 inches near Mammoth to over a foot in southern sections. The Bighorn Mountains and Wind River Range will also see heavy snow and dangerous travel conditions through the day.
Officials urge travelers to delay mountain travel, carry emergency supplies, and check WYDOT road updates. Warnings remain in effect through Friday evening, and conditions may worsen quickly in higher elevations.
