Highlights

Significant precipitation last night and this morning has increased the load over the deep persistent weak layer of basal facets. Any avalanches triggered on this layer will be significant.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–3
    Wind slabs up to 1m deep can be triggered by a person in avalanche terrain. An additional 20 to 30 cm of snow in the past 24 hours has increased the likelihood of triggering these slabs.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    2–3
    If surface slabs are triggered, they now have enough mass that stepping down to the basal facets is likely especially on larger slopes that have not yet avalanched.
