Tetons

At the mid and upper elevations, backcountry travelers could trigger soft slabs up to 18 inches in depth on steep, avalanche-prone slopes. The possibility also continues for hard slab avalanches to be triggered at the base of the snowpack in steep avalanche terrain, even after a slope has been crossed several times. Larger loads, such as snowmobiles or groups of skiers, have a greater potential to cause failure of these weaknesses. At the lower elevations, the avalanche hazard is limited to isolated pockets in very steep terrain.

Limited Pacific moisture in a dirty ridge will continue to bring snow showers to the region. On Thursday skies will be cloudy. An inch or two of new snow could accumulate in the mountains overnight and during the day. Mountain temperatures will be in the teens. Winds will be westerly and increase to 20 to 25 miles per hour.The general avalanche hazard is expected to MODERATE in the Teton and Togwotee Pass/Continental Divide Trails areas and CONSIDERABLE in the Greys River/Southwest Trails area. On steep slopes the potential exists, especially on north and east facing slopes, for humans to trigger pockets of surface slab up to 18 inches deep and deadly full depth hard slab avalanches. Deep hard slabs could be triggered by skiers in all of our forecast areas but are more likely to be triggered by snowmobilers and in the Greys River/Southwest Trails area.
