Soft surface slabs and deep hard slabs could be triggered by humans on steep slopes. The additional load of the recent snowfall has increased the likelihood for humans to trigger these events. Safe travel procedures and conservative terrain choices are essential today.
Soft surface slabs up to 30 inches in depth could be triggered by humans who venture onto avalanche prone slopes. These slabs could step down and trigger dangerous persistent deep slabs in areas with poor snowpack structure.
Dangerous hard slabs up to five feet in depth could be triggered on steep slopes where persistent layers of weak faceted exist within the snowpack. These large to very large slabs could be triggered on slopes that have been crossed multiple times by other riders or skiers.
( Discussion is generated from the previous day's afternoon forecast. )A westerly flow will continue to bring moisture to the region tonight through Monday Night. Accumulations of five to eight inches are possible in the mountains overnight with another three to five inches possible during the day. This snowfall will be accompanied by west-southwest winds at speeds of 20 to 30 with gusts to 50 miles per hour. Temperatures will be in the 20s in the mountains and in the 30s in the valleys where some rainfall will likely occur in the afternoon.The general avalanche hazard is expected to be CONSIDERABLE in the Togwotee Pass/Continental Divide Trails Area and the Southwest Trails/Greys River Area. In the Teton Area it is expected to be CONSIDERABLE at the upper elevations and MODERATE at the mid and lower elevations. Humans are could trigger soft surface slabs one to three feet deep in steep wind loaded avalanche starting zones and in areas with where weak layers of faceted snow persist within the snowpack large dangerous hard slabs up to six feet in depth could be triggered by skiers, riders or snowmobilers.
