Points saillants

As the day warms and the sun impacts snow surfaces, the chance for wet loose and wet slab avalanches will develop first at the lower elevations and move up into the higher elevations later on. These slow moving slides have the potential to entrain significant amounts of snow and become destructive. On sunlit aspects, skiers and riders could trigger these small to large slides, and natural activity could occur. Large to very large deep persistent slab avalanches remain a concern, and this hazard will also increase as the day warms. Cornice failures will be possible, and they could easily trigger a wet slide or a deep persistent slab avalanche. Terrain management is the way to avoid these hazards. Monitor temperatures and the impact of the sun, and transition to shaded slopes when snow surfaces become damp.

    On a variety of aspects and elevations, skiers and riders have the potential to trigger deep persistent slab avalanches, and natural activity may still be possible. As the day warms, these destructive avalanches will become more prone to failure, and involvement will likely result in a fatality. They could also step down from the release of a wet slide. Above 8,000 feet, slab depths are likely to range from 4 to 8 feet and 2 to 4 feet below 8,000 feet.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Cloud cover will decrease overnight, and mostly sunny to clear skies are expected during the day on Sunday. Overnight lows in the mountains will be in the low teens before rising into the mid-30s in the afternoon. Valley temperatures will be a little cooler starting off and then climb to near 40. Southerly to southwesterly ridgetop winds will decrease to 10 to 15 miles per hour.The general avalanche hazard is expected to be Moderate at all elevations on Sunday. In all forecast zones, the chance for wet slides on solar aspects will quickly increase as temperatures warm and the sun impacts snow surfaces. Skiers and riders could trigger these small to large slides, and natural activity could occur. In the Togwotee Pass and Southwest Trails forecast zones, large to very large persistent deep slab avalanches remain a concern, and this hazard will also increase as the day warms. Cornice failures will be possible, and they could easily trigger a wet slide or a deep persistent slab avalanche. Terrain management is the way to avoid these hazards. Monitor temperatures and the impact of the sun, and transition to shaded slopes when snow surfaces become damp. If you are skiing high up in the Tetons, have a plan to safely descend in shaded terrain before you start your day.
