Highlights

The basal weak layers are giving low confidence in the snowpack. Although hard to trigger, any avalanche that is initiated could be large and destructive. Cooler temps should reduce the solar triggered avalanche activity, but keep an eye on this.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–4
    Wind slabs are widespread on lee and cross-loaded features at Treeline and above. Concern for human triggering remains in shallow snowpack areas and convex/unsupported terrain.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    3–6
    Avalanches could step down to the basal October layers and involve the entire winters snowpack. Wide propagations are possible. Shallow snowpack areas are a potential trigger point.

Confidence

Good

Weather Forecast
