Salt River and Wyoming Ranges

The general avalanche hazard is CONSIDERABLE. A well developed, persistent, weak layer of faceted snow and depth hoar lies at the base of the snowpack. The liklihood continues for human triggered hard slab avalanches in steep terrain involving this basal layer. These poorly supported slabs could be triggered by a single person, and more likely a snowmobile, even after a slope has been crossed many times.

( Discussion is generated from the previous day's afternoon forecast. )Friday looks to be mostly dry with a chance for some orographic light snow showers. Temperatures in the mountains are to reach the mid twenties and West winds are to have averages of 15-25 miles per hour. The avalanche hazard is to be Moderate in the Teton and Togwotee Pass areas and Considerable in the Greys River area where the snowpack remains the most sensitive. Backcountry riders and skiers have the potential to trigger hard slab avalanches to the base of the snowpack in steep avalanche terrain. These slabs may fail when a weak spot or trigger point is hit even after a slope has been crossed several times. Larger loads such as snowmobiles or groups of skiers have a greater potential to trigger these weaknesses.
