CASPER, Wyo. — Snowfall will complicate high winds in northeastern Wyoming and the Wind River Range through Wednesday morning, according to the National Weather Service (NWS) in Riverton.

Travel could be very difficult through South Pass, Red Canyon, and especially the Teton and Togwotee Passes, where blowing and drifting snow could significantly reduce visibility, the NWS said.

Winter weather advisories take effect at 11:00 p.m. Monday for Jackson Hole and Star Valley. Total snow accumulations of 3 to 6 inches and winds gusting as high as 45 mph are advised through 11:00 a.m. Wednesday.

Total snow accumulations of 6 to 12 inches are expected in the Teton and Gros Ventre (with higher amounts above 9,000 feet) with snow falling Monday evening. Gusts of 55 mph are expected in the higher peaks.

The alert takes effect for the Wind River mountains at 5:00 a.m. Tuesday. 6 to 12 inches of snow are expected, with higher amounts above 9,000 feet. Winds could be gusting as high as 70 mph in the highest peaks.

Accumulations of 3 to 5 inches are expected through South Pass.
