50-100 cm of recent snow and strong southwest winds have formed storm slabs that will likely be reactive to human triggers; especially in wind-affected terrain at treeline and above.
Continue to make conservative terrain choices while the storm snow settles and stabilizes.
50-100 cm of recent snow and strong southwest winds have formed storm slabs that will likely be reactive to human triggers; especially in wind-affected terrain at treeline and above.
Check out this MIN of a naturally triggered size 3 wind slab avalanche that was reported near Smithers on Friday.
Human triggered avalanches will remain likely at treeline and above on Sunday; especially on wind-loaded slopes.
20-35 cm of new snow brings recent snow amounts to 50-100 cm at treeline and above. Strong southwest ridgetop winds have created thick wind slabs on lee aspects.
The recent snow overlies a variety of problematic snow surfaces including facets and crusts. The snowpack below the recent snow is generally shallow and weak.
The depth of the snowpack at treeline varies from 80-140 cm and tapers rapidly below treeline.
Many early-season hazards such as rocks, stumps, and open creeks exist below treeline.
