Highlights

The general avalanche hazard remain 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. 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 in the afternoon.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies are expected to be mostly sunny again on Saturday. Temperatures will drop to near 10 degrees by daybreak and will rise into the 20s in the mountains and into the 30s in the valleys. Winds will continue to be light and variable. The general avalanche hazard is expected to be LOW at the lower elevations of all forecast areas and at all elevations in the Teton Area. A MODERATE hazard persist at the higher elevations of the Togwotee Pass/Continental Divide and Greys River/Southwest Trails areas where some potential may persist for larger triggers like snowmachines and groups of snowmachines to trigger deep persistent slab avalanches in isolated areas. These dangerous slabs could be up to six feet deep. Isolated pockets of wind slab up to 18 inches in depth could also be human triggered at the upper elevations in all forecast areas.
