The general avalanche hazard is CONSIDERABLE above an elevation of 7,500 feet and LOW below that elevation where snow depths remain shallow. The recent snowfall has increased the load on a snowpack that has poor structure and is unstable. Large human triggered slab avalanches are likely on steep slopes.
At the mid and upper elevations snowmobilers and skiers who venture onto steep slopes could trigger large slab avalanches that fail on persistent weak layers of faceted snow. These slabs could have depths of two to five feet and could fail to the ground in some areas.
( Discussion is generated from the previous day's afternoon forecast. ) A series of arctic cold fronts will move south from Canada and spread across Western Wyoming through much of the week. On Sunday skies will be mostly cloudy with a slight chance for snow showers over the mountains. Temperatures will remain in the single digits and teens. Winds will be light from the west to southwest at 5 to 10 miles per hour.In the Teton Range the general avalanche hazard is expected to be MODERATE. Surface slabs 12 to 30 inches in depth could be human triggered and may have some potential to step down to deeply buried layers of faceted snow. The general avalanche hazard in the Continental Divide/Togwotee Pass and the Southwest Trails/ Greys River areas is expected to be CONSIDERABLE. In those areas large human triggered persistent slabs and surface slabs are much more likely to step down to the ground.
