Highlights

At the upper elevations some potential may remain for humans to trigger slab avalanches in very steep avalanche starting zones. The wet slide hazard is expected to increase on all aspects at the lower elevations and on sunlit aspects at the mid elevations after significant softening of the snow surfaces has occurred. Evaluate the snow and terrain carefully. If the snowpack is wet and unconsolidated, avoid steep terrain.

    At the upper elevations some potential may remain for skiers and riders to trigger pockets of slab up to two feet deep. These dense slab avalanches are most likely to be triggered in steep cliff areas that face east to north where the recent new snow has not fully bonded to the old snow surfaces. Instabilities on that new snow old snow interface may persist due to localized pockets of faceted snow at that interface. These slabs may become more sensitive to human triggers during the warmest portion of the day.

    Wet slides are possible, especially during the warmest portion of the day. At the mid and lower elevations these slides could dig down into older snow layers on steep terrain features where rising temperatures create areas of unconsolidated, isothermal snow.

Avalanche Discussion

Unsettled weather in a southwest flow will continue to bring weather disturbances to Western Wyoming. Tomorrow, skies are expected to be partly cloudy with periods of light snowfall. Overnight, temperatures will drop into the teens and then climb into the 20s and 30s with valleys reaching the low 40s. Ridgetop winds are expected to be westerly and range from 10 to 20 miles per hour. For the Togwotee Pass forecast area, the hazard above 9,000 feet is Moderate, where skiers and riders could trigger wind slab avalanches up to 2 feet in depth on wind loaded slopes. For the Greys River and Teton forecast areas, the general avalanche hazard is expected to be Low, where below 10,500 feet the snowpack is mostly stable. In the Tetons at the upper elevations, skiers and riders could still trigger slab avalanches up to 18 inches in-depth in isolated areas on steep terrain. Afternoon warming and periods of clear skies could result in wet loose activity on solar aspects and below 7,500 feet. Due to the unexpected challenges involving Covid-19 and the overloading of our healthcare system, it is important to make conservative choices. Please use cautious evaluation and make efforts to avoid injuries. Thank you.
