Lo esencial

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 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, and previous tracks on a slope should not be mistaken as an indication of stability. At the lower elevations, isolated pockets of slab could have crown depths up to two feet deep.

Avalanche Discussion

With clear skies, temperature inversions will increase overnight with valley lows near negative 10. The mountains will start out in the upper single digits before rising into the upper 20s. Northwesterly ridge top winds will range from 10 to 20 miles per hour.The general avalanche hazard is expected to be CONSIDERABLE in the Greys River and Togwotee Pass areas on Friday. Dense human triggered slides, two to five feet in depth, are probable on a variety of aspects. In the Tetons, the general avalanche hazard is expected to be MODERATE. Similar slides are possible and could be triggered in isolated areas. In all forecast areas, the consequences of being caught in one of these slides remain high, and the likelihood of triggering these slides may increase in the afternoon with daytime warming. Do not let previous tracks lull you into a false sense of security as they are not an indication of stability.
