Highlights

In the higher elevations, backcountry travelers could trigger small pockets of winds slab in steep, wind loaded terrain. Keep an eye out for drifting snow, and avoid steep slopes with significant deposits. Remember, even small slides can have serious consequences above cliff bands or in long, sustained couloirs. With the current stress on our health care community, an extra margin of safety is warranted.

    The recent snowfall has settled significantly over the past three days and has mostly stabilized after temperatures cooled overnight. In very steep terrain at the upper elevations, skiers and riders might be able to trigger a small pocket of wind slab involving this snow. As the day progresses, strong southwesterly to westerly ridgetop winds will transport new snow and any remaining available snow forming new pockets of wind slab up to a foot deep by this evening.

Avalanche Discussion

A large low-pressure system is dropping south along the coastal waters of the Pacific Northwest. As the leading edge of this low moves into Western Wyoming snow shower activity will increase and will continue to favor the southern portions of the Greys River area. Snowfall amounts of 3 to 6 inches are likely down there during the next 24 hours. A weak cold front will pass through the region later tonight. On Wednesday temperatures will be in the single digits and teens in the mountains and rise from the teens into the 30’s in the valleys. Winds will veer to the west at 15 to 25 miles per hour.Cooler temperatures will decrease the wet snow avalanche hazard. Moderate southwest to west winds will continue to form small pockets of wind slab at the upper elevations. Those slabs could be triggered by humans with depths to 18 inches. The general avalanche hazard is expected to be moderate above an elevation of 9,000 feet in the Greys River/Southwest Trails area and between an elevation of 9,000 and 10,500 feet in the Teton area. In those areas the hazard will be low below 9,000 feet . The hazard is expected to be low at all elevations of the Togwotee Pass area.
