The general avalanche hazard is MODERATE above an elevation of 9,000 feet. At these high elevations, wind slabs could be triggered by backcountry skiers and riders today. Very steep terrain should be avoided as varying winds have resulted in the formation of these slabs on multiple aspects. Evaluate snow and terrain carefully and avoid features of concern. Soft wind slab avalanches could be human triggered in very steep terrain. A remote chance also persists for snowmobilers to trigger deep hard slab avalanches in isolated avalanche paths. Avalanches are unlikely below 9000 feet where the snowpack is mostly stable.
Pockets of wind slab could be human triggered today at the upper elevations. These slabs are made up of both new and recent snowfall with depths to two feet. They could become more sensitive as they are weakened by warming temperatures and potential additional snowfall.
( Discussion is generated from the previous day's afternoon forecast. )The National Weather Service has issued winter weather advisories or winter storm warnings for western Wyoming. A storm centered over the great basin and moving east will bring snow to the area tonight and Tuesday. This storm will favor the southern forecast areas yet widespread accumulations are expected in all areas. Four to eight inches could fall by morning with more snow expected during the day. Northeast winds are to have averages of 15 to 25 mph.The general avalanche hazard will be Moderate above 9000 feet where wind slabs to two foot depths could be triggered in steep terrain. Snowfall and Northeast winds are not common so watch for loading in atypical areas tomorrow. A slight chance for deeper instabilities to be triggered in isolated areas also continues in high terrain in the Togwotee Pass area. Avalanches below 9000 feet are unlikely in the mostly stable snowpack.
