Tetons

New snow and westerly winds in the past twenty four hours have created pockets of surface slabs to twelve inches in depth on lee slopes at the upper elevations. Slides could be triggered by backcountry travelers on steep slopes near ridge crests. At mid and low elevations the snowpack is mostly stable.

The active weather pattern will continue with another disturbance bringing 6 to 10 inches of snow to the Tetons by noon Wednesday. The Greys River area will receive 3 to 6 inches of snow and the Togwotee Pass area 4 to 7. Mountain temperatures will be in the upper teens Wednesday morning then rise into the low twenties. Winds will be westerly overnight then southwesterly Wednesday at 20 to 30 miles per hour.New snow and winds will create the potential for easily triggered, soft slabs to two feet in depth at Mid and Upper elevations in the Tetons where the avalanche hazard is expected to rise to Considerable. Slabs will be likely on steeper lee slopes and quick running oft slabs or sloughs on areas with buried sun crusts. The Greys River area is forecasted to receive enough snow and wind to create areas of soft slabs and/or sloughs on sun-crusted and steep, lee slopes where the hazard is expected to rise to Moderate. The Togwotee Pass area will remain at Low unless significant snowfall occurs.
