Tetons

At the mid and upper elevations, the avalanche hazard will increase during the day as warming temperatures, dense new snow and strong southwesterly to westerly ridgetop winds continue to build surface slabs which rest on slick sliding surfaces and lighter density snow. In steep, wind loaded terrain, backcountry travelers could trigger these slabs up to two feet deep by this evening. Prolonged periods of afternoon rain could also bring about the possibility of wet slides at the lower elevations.

Snowfall intensity will decrease overnight followed by a brief lull on Wednesday before the next weather system begins to move through Wednesday night. Overnight lows in the mountains will be in lows teens before rising into the mid 20s during the day. Southwesterly to westerly ridgetop winds will decrease to 10 to 20 miles per hour.The general avalanche hazard is expected to be CONSIDERABE in the higher elevations of Teton and Greys River areas. There, backcountry travelers could trigger dense, dangerous surface slabs up to two feet in depth on steep, wind loaded slopes. In the Togwotee Pass area, the general avalanche hazard is expected to be MODERATE. Skiers and riders could trigger newly developed pockets of soft slab up to a foot deep in steep, wind loaded terrain.
