Tetons

Up to 10 inches of new snow has accumulated on the west slope of the Teton Range since Saturday. This new snow lies upon slick old snow surfaces and surface hoar. Loose snow slides involving this new snow and small, isolated pockets of new soft slab up to one foot in depth could be triggered by skiers and riders in steep terrain. These small slides could become a danger in cliff areas, above terrain traps and can produce sizable debris piles at the base of steep sustained pitches and couloirs.

A brief break between weak weather systems will occur overnight. Skies will be mostly clear until midnight. Moisture, clouds and warm air aloft will begin to move into the region during the early morning hours. Temperatures should be inverted at daybreak with lows in the coldest valley locations in the single digits and temperatures at 10,500 feet near 20 degrees. Light snowfall or flurries will begin in the mountains at daybreak and become widespread during the day with accumulations of two to three inches possible by sunset. Temperatures will rise into the 20s. Winds will be southerly at five miles per hour and veer towards the southwest and increase to 12 miles per hour in the afternoon.The general avalanche hazard is expected to remain LOW in all areas except for the upper elevations of the Togwotee Pass region where the hazard will be MODERATE. Hard slab avalanches up to three feet in depth could be human triggered on north facing slopes in isolated areas above an elevation of 9,000 feet in the Togwotee Pass area.
