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 temperatures warm and snow surfaces soften. At the lower elevations the snowpack is mostly stable and avalanches are unlikely.

    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 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. )Skies will be mostly clear overnight with temperatures forecast to drop to near 10 degrees in the mountains and in the valleys. On Sunday skies will be clear in the morning and are expected to be overcast by evening as a weather system dropping southward from Montana moves towards the region. Daytime temperatures will rise into the upper 20s and 30s in the mountains ahead of this approaching system. West winds will be on the increase and veering towards the northwest at speeds of 15 to 25 miles per hour with higher gusts. The general avalanche hazard is expected to be LOW in the Teton Area and below an elevation of 8,000 feet in the other forecast areas. Lingering potential for deep slab instabilities is isolated areas will keep the hazard MODERTAE above an elevation of 8,000 feet in the Continental Divide/Togwotee Pass and the Southwest Trails/Greys River areas.
