The general avalanche hazard is MODERATE above an elevation of 8,500 feet and LOW below that elevation. Some potential may remain for humans to trigger large slab avalanches in steep terrain on buried old snow surfaces that are faceted. Small pockets of new wind slab may begin to form on leeward aspects along the highest ridge lines.
Large slab avalanches could be human triggered on old snow surfaces on west through north to east aspects at the upper elevations and on northerly aspects down to an elevation of 8,500 feet. These slabs could be up to three feet deep at the upper elevations and up to two feet deep at the mid elevations.
( Discussion is generated from the previous day's afternoon forecast. )A Pacific low pressure trough will bring snow to the mountains of western Wyoming tonight through Friday. Accumulations of 4 to 6 inches at the higher elevations and 1 to 3 inches at the lower elevations are likely. Temperatures will be in the teens and 20s tonight and rise into the 20s and 30s on Friday. West to southwest winds will increase to 25 with gusts to 40 miles per hour.The general avalanche hazard is forecast to be MODERATE above an elevation of 8,500 feet and be LOW below that elevation.
