Highlights

At the mid and high elevations, skiers and riders have the potential to trigger slabs that lie upon faceted snow within the snowpack. Warming temperatures today will increase the potential to trigger these persistent slabs.

    Weak faceted snow persists in the snowpack. In some areas this snow exists as layers that vary in thickness while in shallow areas the entire snowpack can be faceted. Consolidated snow resting on these layers can be triggered by backcountry enthusiasts. These slabs could be shallow and small in size or could be significantly larger and release to depths of 30 inches. In north facing terrain above 9000 feet some potential remains for full depth avalanches.

Avalanche Discussion

A small upper level disturbance from the southwest and cold arrive from the north are to collide over the area resulting in the chance for snow tonight through tomorrow. Two to five inches could potentially fall in the mountains while up to three inches could fall in the valleys. High temperatures in the mountains are to reach the upper teens and west-southwest winds are to average ten to twenty miles per hour. The general avalanche hazard is expected to be Moderate at upper elevations in the Togwotee Pass and Teton areas and at all elevations in in the Greys River Area. In such avalanche terrain backcountry travelers could trigger slabs that lie upon faceted snow to depths of thirty inches. In steep north facing terrain above 9000 feet a slight potential persists for full depth avalanches at the base of the snowpack.
