Expect to find new storm and wind slabs, which may not bond well to previous surfaces.
Snow and strong wind are forming new storm and wind slabs. All this new snow may not bond well to previous surfaces and could be easily triggered by riders.
We haven't received any notable avalanche reports during last week's cold spell. Looking forward, storm and wind slab avalanche activity is anticipated to increase with snow, wind, and warm air.
Please continue to share any observations or photos on the Mountain Information Network.
Stormy conditions return, with upwards of 40 cm of snow expected to accumulate between Friday morning and Saturday afternoon. The snow is falling with strong wind from the southeast switching to the southwest, forming wind slabs in lee terrain features. All this snow may not bond well to previous surfaces that include small surface hoar crystals, sugary faceted grains, and hard wind-packed snow.
The snowpack is still fairly thin and faceted, with roughly 120 cm at treeline.
