Tetons

The chance continues for backcountry travelers to trigger hard slab avalanches to the base of the snowpack in steep avalanche terrain. These slabs may release even after a slope is crossed several times when a trigger point is impacted or to heavier loads such as snowmobiles. At the low elevations hazard is limited to isolated pockets in very steep terrain while at the mid and high elevations large dangerous pockets are susceptible in the deeper snowpack. In very steep terrain sluffs and soft slabs to a foot in depth near ridge crests are also possible.

A few light flurries could develop overnight as a Pacific low pressure system brushes the region to the south, followed by decreasing cloud cover during the day. Overnight lows in the mountains will be in the mid teens before rising into the mid 20s on Sunday. Ridgetop winds will veer to the northeast at 10 to 15 miles per hour.The general avalanche hazard is expected to be MODERATE in the Teton and Togwotee Pass areas, and CONSIDERABLE in the Greys River area where the snowpack remains more sensitive. In steep avalanche terrain, the possibility persists for backcountry riders and skiers to trigger hard slab avalanches to the base of the snowpack. These slabs may fail after a slope has been crossed several times if a shallow weak zone is encountered. Larger loads, such as snowmobiles or groups of skiers, have a greater potential to cause failure of these weaknesses. In steep terrain, loose snow sluffs and pockets of soft slabs to a foot in depth could be triggered near ridge crests. Any extended periods of sunshine will increase the likelihood of these slides.
