Lo esencial

Last weekend's storm dropped one to one and a half feet of heavy snow at mid and upper elevations. On shaded aspects at upper elevations the snowpack rests on weak layers of faceted snow over firm crusts.Sun crusts have developed on sunlit aspects and surface hoar exists on most shaded and lower angle slopes.

    On northerly to easterly aspects at upper elevations people have the potential to trigger dangerous, firm avalanches to two feet in depth on steep terrain. Slides will be difficult to predict and may need larger triggers such as snow machines or more than one person at a time on a slope. At mid and low elevations the snowpack is mostly stable but be alert to the possibility of isolated pockets of slab on steep, north facing slopes at mid elevations.

Avalanche Discussion

A fast moving Pacific system is to deliver one to three inches of snow to the mountains between tonight and late morning Thursday. Warm temperatures will result in a mix of snow and rain in the valleys as well as in some mountain locations. Southwest winds averaging 20-25 mph are to accompany this snowfall. The general avalanche hazard is expected to be Moderate in the Teton area tomorrow. In isolated areas above 9000 feet, pockets of slab lie on crusts formed in October. These slabs could be triggered in very steep terrain with depths up to two feet. In the Togwotee Pass area and the Southwest Trails area where the rating will be Low, hazard is likely limited to isolated pockets of slab in high, steep Northerly terrain.
