Tetons

Mostly stable snow exist and avalanches are unlikely except in isolated pockets. Shallow pockets of wind slab 6 to 12 inches in depth could be human triggered in steep terrain. These small slides could knock a person over or sweep them down a very steep slope or over a cliff. Loose snow sluffs are possible on steep sunlit aspects, especially during the warmest portion of the day. Normal caution is advised.

Temperature inversions will rebuild overnight with lows in the mountains near 20.The valleys will dip into the low teens. During the day, mountain highs will be in the mid-30s as the valleys rebound to close to 40. Skies will be mostly clear above areas of morning valley fog. Westerly ridgetop winds will back to the northeast at 5 to 15 miles per hour.On Friday morning, the general avalanche hazard is expected to be Low in the Tetons and Moderate in Togwotee Pass and Greys River areas. Skiers and riders might be able to trigger a pocket of shallow wind slab in very steep, wind-loaded terrain. In the Togwotee Pass area, which has a shallow continental snowpack, deep persistent slabs could be triggered that fail in faceted snow near the ground. Similar slides are possible in the Greys River forecast zone in areas with shallow snow depths. These areas would most likely be found in the eastern portion of the forecast zone, which is in the rain shadow of the Salt River Range. As the day warms, both shallow wind slabs and deep persistent slabs could increase in likelihood, particularly on sunlit aspects. Small loose snow sluffs and cornice failures will also become possible with daytime warming.
