In sintesi

At the highest elevations isolated pockets of wind slab up to a foot in depth could be human triggered in very steep avalanche starting zones and cliff areas. The primary hazard at the mid and upper elevation are persistent deep slabs. These hard slabs are unstable in isolated areas on all aspects. Conservative terrain choices continue to be warranted. Avalanches are unlikely at the lower elevations.

    At the mid and upper elevations hard slabs, with depths to five feet, lie upon persistent weak layers of faceted snow. We believe these dangerous slabs could still be triggered by the weight of a single person but are more likely to be triggered by snowmobiles or groups of people. The most likely trigger points are areas where the slab is thin. Previous tracks and the lack of recent avalanche activity are not indications of stability.

Avalanche Discussion

Skies will continue to be at least partly cloudy with a chance of snow flurries, light snow showers and areas of morning valley fog. Temperatures will remain in the single digits and teens. Winds will remain west-northwesterly and are forecast to diminish to 5 to 15 miles per hour.At the upper elevations pockets of surface slab formed by west-northwest winds with depths to 18 inches could be human triggered in steep avalanche starting zones and cliff areas. Persistent slabs with depths from two to five feet continue to be a threat at the mid and upper elevations. These slabs are likely to be more sensitive to human triggers in the Togwotee Pass and Greys River areas and may be human triggered in isolated areas on a variety of aspects in the Teton forecast area. The general avalanche hazard is expected to be MODERATE at the mid and upper elevations and LOW below an elevation of 7,500 feet.
