Tetons

At the mid and upper elevations, the possibility persists for backcountry travelers to trigger hard slab avalanches to the base of the snowpack in steep avalanche terrain. These slabs may fail after a slope has been crossed several times if a shallow weak zone is encountered. Larger loads, such as snowmobiles or groups of skiers, have a greater potential to cause failure of these weaknesses. Yesterday, a skier triggered an 18 inch soft slab on an east facing aspect in Avalanche Bowl on Teton Pass. Similar surface slides, along with loose snow sluffs, are also possible today. As the day warms, these slides will become more susceptible to failure. At the lower elevations, the avalanche hazard is limited to isolated pockets in very steep terrain.
