Degrees of Avalanche Danger ?
The danger is generally moderate, meaning human-triggered avalanches are possible. However, there are going to be pockets of considerable danger on wind loaded slopes.
All the recent wind has loaded south through east aspects and gullies with several layers of hard wind slab. The slabs appear to be thin (less than 30cm thick) in most areas , but thin wind slabs can be quite dangerous, and can step down to deeper layers below. In steep terrain slabs may break fast and propagate wide, as well as uphill above the rider. Probe around for strong-over-weak layering, and listen for hollow sounds under your feet. These will be indications of poor snowpack structure and signal extra caution. Remember that convex slopes are particularly weak.
Recent Avalanche Activity
Our last snowfall was on the 7th, when 12-15″ of low-density snow piled up. Since then, strong north-northwest winds have whipped the snow around, hammering most alpine slopes.
Cold and breezy will continue Thursday and Friday. By Saturday the flow will turn more onshore, bringing light snowfall in the 3-6″ range through Sunday. Heavy snow and strong warming is likely from Monday on.
Additional Info & Media
Use standard backcountry practices to minimize your risk. This means traveling one-at-a-time through steep areas, using safe zones to stop and rest, and never traveling above your partners. Don’t commit to any slopes steeper than 30 degrees without thoroughly evaluating the snow on that slope, and making a plan for managing the danger/terrain. Even small slides can pile up deep. Stay out of gullies, depressions, and terrain traps. ALWAYS wear a beacon, shovel, and probe and know how to use them.
