Strong westerly winds have formed new wind slabs at upper elevations.
Strong wind continues to reshape the snowpack. Be cautious anywhere that looks extra deep or where the wind is actively moving snow.
A persistent layer remains a concern in this region.
Strong westerly winds have formed new wind slabs at upper elevations.
A crust with facets buried 50 to 170 cm produced a widespread cycle of natural and human-triggered avalanches just over a week ago. Remote triggering and step-down potential continue to be a concern with this layer.
No new avalanches have been reported but observations have been limited. If you head into the backcountry, consider sharing your observations with the Mountain Information Network.
Strong westerly wind has blown 25 cm of recent snow into slabs in leeward alpine and treeline terrain.
A crust from mid December, surrounded by weak facets, is buried 50 to 170 cm deep, depending on aspect and wind loading. Just over a week ago, a large natural avalanche cycle ran on this layer.
In thin snowpack areas, faceted grains or depth hoar may exist at the base of the snowpack.
