Tetons

New snow is falling on a mostly stable snowpack. As snowfall accumulates at the mid and upper elevations, the possibility for backcountry riders and skiers to trigger loose snow sloughs and isolated pockets of shallow soft slabs could develop in very steep terrain and wind loaded features. Avalanches are not expected at low elevations where the snowpack has undergone several melt-freeze cycles.

Snow shower activity is forecast to decrease as the low pressure system passes over the Continental Divide and moves east. Several inches of snowfall are possible in favored areas overnight. Some low clouds and light snow showers are likely over the mountains on Sunday. Temperatures will be slightly cooler. Winds will veer from the southwest to the northwest at speeds of 15 to 20 miles per hour.The general avalanche hazard is expected to be MODERATE in the Togwotee Pass and Greys River areas where deep slab instabilities may still be a concern for snowmachines who climb steep avalanche prone slopes. Although the likelihood of triggering a dangerous hard slab avalanche is low, the consequences remain severe. In the Teton area new snow depths vary. At the higher elevations pockets of wind slab up to a foot in depth and loose snow sluffs could be triggered by skiers and riders and steep avalanche starting zones. These small slides could pose a hazard in cliff areas, steep couloirs and above terrain traps. The general avalanche hazard is expected to be LOW, however areas of higher hazard may be found if overnight snowfall amounts exceed expectations.
