Highlights

It is possible for skiers and riders to trigger small to large persistent slab avalanches on steep avalanche prone terrain above 7,500 feet. The likelihood of triggering these slabs will be difficult to predict and previous tracks should not be taken as a sign of stability. Persistent slab avalanches are most often triggered by a large load or when a thin spot in the slab is crossed. Warming temperatures today may increase the sentivity of these slab avalanches to human triggers, Below 7,500 feet, the snowpack is mostly stable and avalanches are unlikely except for small isolated pockets on steep terrain features.

    Poor snowpack structure is widespread on Togwotee Pass. Basal facets, near-surface facets, surface hoar, and crusts all persist in the snowpack. On a variety of aspects above 7,500 feet, skiers and riders continue to have the potential of triggering persistent slab avalanches that could have depths of one to three feet. Large triggers, such as snowmobiles, are more likely to initiate one of these slabs.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Moisture will continue to flow into region. A brief decrease in snowfall intensity is anticipated overnight with the main accumulation across Yellowstone Park and the far northern Tetons. Increased snowfall rates will return in the morning and spread south into the Salt River and Wyoming Ranges by early afternoon. Overall additional accumulations of 5 to 10 inches are anticipated in the Tetons with 4 to 8 inches expected in the Salt River and Wyoming Ranges. Temperatures will continue to climb further into the 20s in the mountains on Friday. Valley’s will reach 30 degrees. Winds will be from the south to southwest at 5 to 20 miles per hour.The general avalanche hazard is expected to be moderate in the Greys River and Togowtee Pass areas. In those areas, humans could trigger persistent slab avalanches one to four feet deep on steep avalanche prone slopes. More snow and warming temperatures are likely to keep the avalanche hazard at considerable in the areas of the Teton Range that were slammed by snow today. In those areas dangerous sluffs and large slab avalanches could by human triggered on steep slopes.
