Highlights

The general avalanche hazard remains MODERATE above an elevation of 8,000 feet where some potential may persist for snowmobiles to trigger deep hard slab avalanches in isolated areas where weak faceted snow persist near the base of the snowpack. These dangerous slab avalanches are more likely to be triggered when multiple sleds are on a suspect slope at the same time and after sunshine and warm and warm temperatures have softened the snow surfaces. Mostly stable snow exist at the lower elevations and avalanches are unlikely except for shallow wet slides on very steep sunlit aspects during the heat of the day.

    In isolated areas weak, faceted snow persists near the base of the snowpack. Some potential may remain for snowmobilers or multiple snowmobiles on the same slope to trigger dangerous hard slab avalanches up to six feet deep. In these areas previous tracks on a slope are not an indication of stability. If a member of your party gets stuck on a suspect slope, refrain from adding additional weight to the snowpack by helping them get unstuck.

    At the upper elevations isolated pockets of wind slab up to eighteen inches in depth could be triggered by skiers or riders who venture onto very steep slopes, into areas with cornices and into cliff areas. Sunshine and warming temperatures may make these shallow surface slabs more sensitive to human triggers.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )The system passing to our north and east will continue to bring clouds and possibly a little snow to the higher elevations of the northern and eastern portions of our forecast area. During the night winds will veer towards the northwest and temperatures will drop into the teens. Expect clearing skies on Monday. Temperatures will rise into the 30s in the mountains and into the 40s in the valleys. Winds will be westerly at 10 to 20 miles per hour.A mostly stable snowpack exists. Isolated pockets of hard wind slab could be human triggered in very steep terrain, cliff areas and along corniced ridgelines. The general avalanche hazard is expected to be LOW in the Teton area and in the lower elevations of the Continental Divide/Togwotee Pass and the Southwest Trails/Greys River areas. A MODERATE hazard is expected at the mid and upper elevations of the Continental Divide/Togwotee Pass and the Southwest Trails/Greys River areas where some potential for snowmobiles to trigger deep hard slabs to depths of six feet may persist in isolated areas.
