Very warm temperatures and intense sunshine will increase the wet slide avalanche hazard as the day warms. Wet loose and small wet slab avalanches are possible on a variety of aspects in very steep terrain. Cornices may become unstable and could trigger large slab avalanches. Deep hard slab avalanches continue to be a potential hazard in steep upper elevation active avalanche paths. Monitor conditions and avoid steep avalanche prone terrain after significant warming has occurred and snow surfaces have softened.
Warming conditions will increase the potential for snowmobiles to trigger deep hard slab avalanches in very steep upper elevation avalanche paths. These slabs could have depths from two to four feet.
Wet loose slides are possible in very steep terrain on a variety of aspects after snow surfaces soften. These slides could catch and carry people down steep slopes.
Cornices could become unstable as the day warms. Cornice releases can be unpredictable and can break further back than anticipated. Cornice failures could trigger large wet slab avalanches on steep slopes. Avoid cornices and the slopes beneath them.
( Discussion is generated from the previous day's afternoon forecast. )Conditions will remain dry under a high pressure ridge. Skies will be mostly clear. Temperatures are forecast to drop into the upper 20s overnight and rise into the 40s and 50s in the mountains and into the 60s in the valleys. Winds will relax to speeds of five to ten miles per hour and veer towards the north.The general avalanche hazard will be LOW in the early morning hours and increase to MODERATE after snow surfaces soften. Wet loose and small wet slab avalanches will become possible in very steep terrain. Cornice failures will become a possibility and could trigger large slab avalanches on steep slopes. Deeper hard slabs may become sensitive to human triggers in isolated locations at the upper elevations in the Togwotee Pass and Greys River areas. Monitor conditions and avoid steep avalanche prone terrain after significant warming occurs.
