Points saillants

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.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité

    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

    • Limite forestière
    • Sous la limite forestière

    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
