Tetons

The general avalanche hazard on steep slopes with old snow is low. The recent new snow lies upon surface hoar and old snow surfaces comprised of faceted snow and crusts. On very steep slopes, new snow could be triggered into loose snow sloughing on the interface between the new and old snow. If winds create soft slabs they are likely to be easily triggered by humans and could dig down into the older snow.

The next round of snowfall is expected to start in the early morning with snow continuing through the day on Wednesday. This system is expected to favor the Teton and Wyoming ranges with two to five inches possible at the higher elevations by the evening. Temperatures that are to drop below zero in the mountains are to have highs in the low teens while varying winds remain relatively light with five to twenty mile per hour averages. In the valleys, temperatures are to again swing from the single digits to the twenties. The general avalanche danger will remain Moderate in the Togwotee Pass area where loose snow sloughs and small wind slabs could be human triggered in steep terrain. In that area, more new snow has fallen and the old faceted snow cover is more prevalent. The danger will remain Low in the Teton and Southwest Trails areas where similar hazards exist in isolated areas. Predicted new snowfall and moderate winds will increase the chance for loose snow sloughing and for triggering small soft slabs as the day progresses.
