In sintesi

Snow surfaces will soften during the day and increase the wet snow avalanche hazard. Shallow wet slides could be human triggered on steep slopes, cliff areas, steep banks and road cuts during the warmest portion of the day. Large deep persistent slab avalanches are unlikely but still a potential threat. Due to the substantial consequences of being involved in one of these dangerous slides a conservative approach to steep suspect slopes is warranted. Other dry snow avalanche hazards are limited to isolated pockets of wind slab less than a foot deep. Even small slides can sweep backcountry travelers over cliffs, carry them down very steep slopes or bury them in terrain traps. Monitor conditions for increasing wet snow avalanche hazard and avoid avalanche prone terrain after snow surfaces become soft and lose cohesion.

    No large slab avalanches have been reported in over two weeks. Although these dangerous slides are unlikely some potential may remain for backcountry travelers to trigger deep persistent slab avalanches on buried layers of faceted snow. A larger trigger like a snowmobile or a cornice drop may be necessary to trigger one of these deep slab avalanches. They could occur on slopes that have been previously tracked. These low probability high consequence slides could be 3 to 5 feet deep and cause serious injury or death.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Conditions will be partly to mostly cloudy and slightly cooler with scattered snow showers on Tuesday. Snow shower activity is anticipated to favor the southern portion of the Greys River areas. Accumulations of a trace to an inch or two are possible. Temperatures are forecast to fall to near 20 degrees overnight and rise into the upper 20’s and 30’s in the mountains. Winds will be light at 5 to 15 miles per hour from the northwest to east. The general avalanche hazard is expected to be low. Wet snow avalanche hazards will increase on steep terrain features during the warmest portions of the day. In the Togwotee Pass and Greys River areas deep persistent slab avalanches are unlikely but cannot be ruled out. Some potential may remain for low likelihood, high consequence slab avalanches to be triggered by snowmachines or cornice failures. If triggered these avalanches could be 3 to 5 feet deep.
