A slight chance persists to trigger pockets of persistent slab which formed during the last storm cycle. On northerly aspects above 9,000 feet, a slight chance also remains to trigger full depth, hard slab avalanches on weak snow near the base of the snowpack. As the day progresses, the chance for trigging isolated pockets of new, shallow soft slab will increase above 9,000 feet. These slabs are forming above hard crusts and faceted snow. Evaluate the snowpack and terrain carefully, and identify features of concern.
On a variety of aspects and elevations, skiers and riders might be able to trigger persistent slabs from the previous storm cycle in very steep, avalanche prone terrain that was not affected by warm, inverted temperatures. These slabs were formed by strong southwesterly to westerly winds and could have depths to thirty inches at the higher elevations.
Weak snow persists near the base of the snowpack on northwesterly through northeasterly aspects above 9,000 feet. Backcountry uses might still be able to trigger full depth avalanches on this layer in steep, avalanche prone terrain. Large triggers, such as snowmobiles or groups of people, are more likely to be able to impact this weak layer.
( Discussion is generated from the previous day's afternoon forecast. )Expect mostly dry conditions overnight before the chance for light snow showers increases during the day. Overnight lows in the mountains will be in the upper single digits before returning into the upper teens during the day. Southerly ridgetop winds will range from 10 to 20 miles per hour.The general avalanche hazard is expected to be Low in the Tetons. Low hazard does not mean no hazard. Skiers and riders venturing into to very steep, avalanche prone terrain might be able to trigger an isolated pocket of surface slab.In the Togwotee Pass and Greys River areas, the hazard is expected to be Moderate. The primary concern in the Togwotee Pass forecast zone will be persistent deep slabs on northerly aspects above 9,000 feet. In the Greys River area, it will be unlikely to trigger one of these slides, but due to their high consequences it still warrants mention. Pockets of surface slab up to 30 inches deep could also be triggered down south.
