Tetons

A mostly stable snowpack exists in the surrounding mountains. Although avalanches are unlikely, backcountry travelers should always be aware of changing conditions and the possibility of a small surface slide in very steep terrain. During the warmest portions of the day, snow surfaces could warm and destabilize. Also, warm temperatures from the previous few days have formed firm surfaces and created slide for life conditions. Remember to always use safe protocols when traveling through the mountains to maintain good situational awareness.

Cloud cover is beginning to increase ahead of an approaching cold front. This front will bring some moisture with it as well as high winds. Snowfall amounts by tomorrow evening will be 3-5” in the Tetons, and 1-3” on Togwotee and in the Southwest Trails forecast areas. Ridgetop winds will be out of the west at 15-20 mph overnight and increase into the 30-40 mph range as the cold front pushes through during the day tomorrow. Temperatures will be in the low twenties between 8,000 and 9,000 feet.The new snow will likely not change the overall avalanche danger. Isolated pockets of newly formed slabs may be encountered in steep upper elevation wind loaded terrain. Should snowfall amounts exceed what is forecasted, the danger may increase to Moderate in the upper elevations of the Tetons. In all other areas avalanches will be unlikely expect in steep isolated pockets and the danger will be Low.
