In sintesi

The new snowfall will increase the hazard as the day progresses. Yesterday, skiers easily triggered new soft slab avalanches up to two feet in depth. One skier was caught and carried but not buried or injured. Greater amounts of snow has fallen on the west slope of the Teton Range. Soft surface slabs will gain volume and depth as the day progresses and are likely to be increasingly sensitive to human triggers. Some natural avalanche activity is possible at the higher elevations. Safe travel procedures and conservative terrain choices will be essential for safe travel in avalanche terrain.

    Humans who venture into steep terrain and wind loaded avalanche starting zones are likely to trigger soft slab avalanches. The potential for these slabs to release naturally will increase as the day progresses. These slabs are expected to build to depths of one to three feet at the upper elevations and to depths of ten inches to two feet at the mid elevations. Isolated pockets of wind slab up to a foot in depth are possible at the lower elevations by days end.

Avalanche Discussion

A west-southwest flow aloft will continue to feed moisture into the region. Periods of light to moderate snowfall that can be locally heavy at times at the upper elevations. This snowfall will be off and on through the week with no real extended breaks, however accumulations are likely to be significantly less than we have been experiencing lately.Skies are forecast to be cloudy with new snow accumulations of three to five inches likely tonight and again on Sunday in the mountains. Temperatures will be in the teens and 20s in the mountains and in the 20s and 30s in the valleys where some rain is possible during the afternoon hours. Winds will be west to southwest at 25 with gusts to 35 to 40 miles per hour at the summit level. The general avalanche hazard is expected to be CONSIDERABLE in the mountains. Soft surface slabs one to three feet in depth could be easily triggered by humans who venture onto steep avalanche prone slopes. In the Togwotee Pass/Continental Divide and the Southwest Trails/ Greys River areas deep persistent slabs with depths to five feet could also be triggered by skier, snowboarders or snowmobilers. Triggering one of these large dangerous slab avalanches could be fatal.
