Highlights

The snowpack structure is poor. At the mid and upper elevations, backcountry travelers could trigger large persistent slabs which lie upon weak, faceted snow. While the likelihood of triggering these slides is slowly decreasing, the consequences remain high. Skiers and riders might still be able to trigger isolated pockets of shallower slab at the lower elevations. There, avoid terrain traps where even small slides can pile up large amounts of debris.

    At the mid and upper elevations, backcountry travelers could trigger dense slabs with crown depths of two to five feet. These slabs have been triggered in areas where thick deposits of wind-drifted snow have built up in avalanche starting zones. Shallow weak-spots in these slabs should be considered likely trigger points. These slabs may also become more susceptible to failure on sunlit aspects in the afternoon as the day warms. Do not let previous tracks lull you into a false sense of security as they are not an indication of stability. At the lower elevations, isolated pockets of slab could have crown depths up to two feet deep.

Avalanche Discussion

Expect mostly clear skies to continue on Saturday. Overnight lows in the mountains could drop into the single digits before rising into the upper 20s during the day. Northwesterly ridgetop winds will range from 5 to 15 miles per hour.The poor structure of the snowpack will keep the general avalanche hazard CONSIDERABLE in the Greys River and Togwotee Pass areas on Saturday. Dense slabs, two to five feet in depth, lie upon weak, faceted snow and could be triggered on a variety of aspects. In the Tetons, where the faceted snow is less prominent, similar slides remain possible in isolated areas, and the general avalanche hazard is expected to be MODERATE. In all forecast areas, the consequences of being caught in one of these slides continue to be high. Do not let previous tracks lull you into a false sense of security as they are not an indication of stability.
