Tetons
Avalanche danger
Highlights
Low hazard does not mean No hazard. As the day progresses, the chance for trigging isolated pockets of new, shallow soft slab will increase at the upper elevations. These slabs are forming above hard crusts and faceted snow. A slight chance persists to trigger isolated pockets of deeper wind slab from the previous storm cycle on a variety of aspects and elevations in very steep, avalanche prone terrain that was not affected by warm, inverted temperatures.
Avalanche Discussion
Periods of light snowfall will continue overnight before a brief lull takes place. By late afternoon, a more significant Pacific weather system will begin to impact the region. Overnight lows in the mountains will be near 10 degrees before rising into the upper teens during the day. Westerly ridgetop winds will range from 15 to 25 miles per hour.The general avalanche hazard could increase to Moderate in the Tetons depending on the amount of new snow and the strength of the winds. New soft slabs, along with loose snow sluffs, could be triggered by backcountry travelers in steep, avalanche prone terrain above 9,000 feet. These slabs are building just above well-developed sliding surfaces and weak, faceted snow.In the Greys River and Togwotee Pass forecast zones, the lingering chance of triggering deep persistent slab avalanches failing on weak snow near the base of the snowpack will keep the hazard at Moderate. New soft slabs and loose snow sluffs, similar to those in the Tetons, could also be triggered by skiers and riders. This avalanche activity will be more likely to occur down south where snowfall amounts are expected to be greater.
