Stick to your standard safe backcountry travel techniques. Human triggered avalanches are possible. Avoid cornices and continually update your hazard assessment.
Weather Forecast
Today we could see sun, cloud and isolated convective flurries. Temperatures will remain cool with an alpine high of -10 and light winds. The sun could pack some punch today if it breaks through the cloud, this will be the main weather factor influencing the snowpack structure. Snow starting Thursday and we could see up to 20cm by Friday.
Snowpack Summary
~25 cm new snow fell over the past few days burying wind slabs or sun crusts aspect dependent. The late Feb crust/facet combo is down 30-50cm on solar aspects and has potential to be a good bed surface. The January PWL's are buried 150-200cm
Avalanche Summary
Crossover avalanche path had a natural size 3.5 yesterday afternoon! This cornice trigger was an outlier compared to the rest of the avalanche's size and destructive potential, that we observed yesterday. No new avalanches reported from the backcountry, but nearly a dozen relatively small avalanches occurred on extreme terrain in the HWY corridor.
Confidence
Due to the number of field observations
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
