Highlights

New snow and stronger winds overnight have increased the hazard at the upper elevations. Up there skiers and riders could trigger pockets of new wind slab and loose snow sloughs on steep avalanche prone slopes. In steep terrain these slides could quickly gain speed and volume and become dangerous. Small pockets of wind slab may also exist in extreme terrain at the mid elevations. Avalanches are unlikely at the lower elevations.

    At the upper elevations and in isolated terrain features at the mid elevations increased westerly winds have formed fresh pockets of wind slab up to two feet in depth. These slabs and loose snow sloughs could be triggered by skiers and riders who venture into steep avalanche prone terrain features. Periods of sunshine or intense snow shower activity could increase the sensitivity of thes slides to human triggers.

Avalanche Discussion

During the next 24 hours weak disturbances will continue to past over the region in a westerly flow. Skies will be partly to mostly cloudy with periods of light to moderate snowfall and snow shower activity. A couple of inches of new snow are possible overnight and during the afternoon. Winds will back to the southwest and increase ahead of an approaching storm system. Temperatures will be in the teens and 20s. Periods of light snowfall and increasing winds will further the development of wind slabs at the upper elevations. Up there slab avalanches up to two feet in depth could be triggered by skiers and riders in steep avalanche prone terrain. In the Teton Range the general avalanche hazard is expected to be MODERATE at the upper elevations (9,000 to 10,500 feet) and LOW below that elevation. In the Togwotee Pass and Greys River areas the general avalanche hazard is expected to be MODERATE above an elevation of 8,000 feet and LOW below that elevation. In those areas there is also some potential for snowmobilers to trigger large dangerous slab avalanches on steep avalanche prone slopes.
