Southwest to northwest winds have created soft surface slabs. These wind slabs could be human triggered on steep avalanche prone slopes. In a few, steep avalanche paths above 9,000 feet, the chance may persist for skiers and riders to trigger hard slab avalanches that fail on deep instabilities within the snowpack. Avalanches are unlikely below an elevation of 8,000 feet.
Southwest to northwest winds have created pockets of soft slabs. These slabs lie upon firm old snow surfaces and could triggered by humans with depths to two feet.
Weak layers of faceted snow are preserved in the snowpack. At the upper elevations, hard slab avalanches with depths to three feet could be triggered by snowmobilers on steep, avalanche-prone slopes.
( Discussion is generated from the previous day's afternoon forecast. )An unstable northwest flow will continue to bring snow showers to the mountains. Snow shower activity is expected to be heavier before midnight, taper off into the morning and increase again with less intensity on Wednesday afternoon and evening. Temperatures will remain mostly in the teens and 20s. Winds will veer to the west-northwest and decrease from 25 to 15 miles per hour.Dangerous avalanche conditions exist at the higher elevations. The general avalanche hazard is expected to be CONSIDERABLE at the upper elevations of the Teton and Greys River/Southwest Trails areas. Large human triggered avalanches are likely in steep terrain. The general avalanche hazard at the upper elevations of the Togwotee Pass area and the mid elevations of all three forecast zones is expected to be MODERATE. Large human triggered avalanches are possible on steep avalanche prone slopes. The general avalanche hazard at the lower elevations is expected to be LOW.
