Lo esencial

Recent snowfall and strong winds have created pockets of wind slab. Backcountry travelers could trigger these slabs in very steep, wind-loaded terrain. On sunlit aspects, these slabs may become more likely to fail as the day warms. Some potential may remain for skiers and riders to trigger deep hard slab avalanches in isolated areas. Large triggers like snowmobiles, especially multiple snowmobiles on the same slope, are more likely to trigger these dangerous slabs.

    Weak, faceted snow persists near the base of the snowpack in isolated areas. Skiers and riders could trigger dangerous slabs to depths in excess of six feet on this persistent weak layer. Previous tracks on a slope are not an indication of stability. If a member of your party gets stuck on a suspect slope, refrain from adding additional weight to the slope by helping them get unstuck, and keep all other sleds out from underneath that slope.

    Pockets of surface slab up to eighteen inches in depth might be triggered by backcountry travelers who venture onto very steep slopes and into cliff areas. On sunlit aspects sheltered from the wind, these slabs may become more likely to release as the day warms. These slabs have the potential to step down and trigger dangerous deep slab avalanches in areas with poor snowpack structure.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies will be mostly clear Wednesday night and into Thursday before cloud cover increases later in the day. Overnight lows at all elevations will be in the mid teens. During the day, mountain temperatures will reach into the upper 20s as the valleys increase to near 40. Westerly ridgetop winds will range from 25 to 35 miles per hour.The general avalanche hazard is expected to be MODERATE on Thursday. Backcountry travelers could trigger pockets of wind slab six to eighteen inches deep in steep, wind-loaded terrain. The likelihood of triggering these slabs may increase on sunlit aspects as the day warms. In isolated areas of the Togwotee Pass and Greys River forecast zones, some potential may remain for skiers and riders to trigger hard slab avalanches failing on faceted snow deep within the snowpack. Large triggers like snowmobiles, especially multiple snowmobiles on the same slope, are more likely to trigger these dangerous slabs, which could have depths in excess of six feet. As the day progresses, shallow wet slides involving the new snow will also become possible at the lower elevations where temperatures will rise well above freezing.
