CHEYENNE, Wyo. (AP) — Heavy snow in western Wyoming is providing fresh powder for the state's premier ski resort area with Jackson Hole Mountain Resort recording 20 inches in as many hours.

But it's also prompting avalanche warnings for the surrounding mountains where up to 46 inches has fallen with more expected before the storm subsides Friday morning.

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 recorded 100-mph wind gusts in the Wyoming Range on Wednesday.
