Cheyenne, Wyoming – Mountain travel in southern Wyoming could become impossible by 2 p.m. Tuesday as heavy snow and 70 mph wind gusts slam the Sierra Madre and Snowy ranges, triggering whiteout conditions and rapidly drifting roadways.
According to the National Weather Service in Cheyenne, a Winter Weather Advisory remains in effect from 2 p.m. Tuesday through 5 p.m. Wednesday for elevations across the Sierra Madre Range and Snowy Range, including the communities of Centennial and Albany. Forecasters expect 8 to 14 inches of snow, with higher totals above 10,000 feet. Wind gusts up to 70 mph will drive blowing snow, reducing visibility to near zero at times.
High mountain passes, including stretches near Wyoming Highway 130, could see sudden closures as snow drifts and crosswinds intensify. WYDOT warns that conditions may deteriorate quickly Tuesday evening and remain hazardous through the Wednesday afternoon commute. Backcountry recreation will carry serious risk, especially for hunters, hikers, and snowmobilers who could become disoriented in falling and blowing snow.
Officials urge travelers to delay non-essential trips, carry winter survival gear, and check 511 for the latest road conditions. Additional advisories or upgrades remain possible if snowfall rates increase or winds strengthen further.
