Salt River and Wyoming Ranges

The general avalanche hazard is CONSIDERABLE. Unstable conditions exist on steep, snow-covered slopes. Dangerous soft and hard slabs 3 to 6 feet in depth could be human triggered, or release spontaneously, on steep slopes and could run full path. Increasing forecasted snow and wind will increase the hazard.

( Discussion is generated from the previous day's afternoon forecast. ) Tuesday night into Wednesday a quick moving storm system is forecasted to bring 6 to 8 inches of new snow to the Tetons, 5 to 7 inches to the Greys River area and 4 to 6 inches to the Togwotee Pass area. Winds with the system will be southwesterly tonight then westerly Wednesday with ridge top averages of 40 miles per hour. Temperatures will rise from four degrees in the morning to eleven in the afternoon. New, sensitive surface slabs will develop with the forecasted wind and snow. Slides will have the potential to pull out deeper, unconsolidated older snow resulting in large debris volumes. Surface slides will also be possible in the Greys River region. Deeper slabs are also possible there as weak, faceted snow sits at the base of the snow pack. In the Togwotee Pass area the snowpack is shallower and there has been less new snow but deep slabs, likely requiring larger triggers, are possible.
