Heavy snow in western Wyoming is providing fresh powder for the state’s premier ski resort area. But it’s also prompting avalanche warnings for the surrounding mountains.


Winter storm warnings are posted for western Wyoming until 5 a.m. Friday.

The storm has already dumped up to 20 inches of snow and up to 4 feet is possible in some areas before it’s over.

A 12-mile section of Wyoming 22 between Jackson and the Idaho state line was closed most of Thursday morning and no unnecessary travel was advised on a 55-mile section of U.S. 26-287 between Dubois and Grand Teton National Park.

Elsewhere, winds gusting up to 65 mph are hampered traffic along Interstates 80 and 25. The National Weather Service record 100-mph wind gusts in the Wyoming Range on Wednesday.
