Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2.5

    Snow and moderate winds forming new slabs on leeward and cross-loaded terrain features. These slabs will probably not bond well to the current snow surface.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1.5–3

    Be cautious of thick to thin snowpack areas being likely trigger locations.

Weather Forecast

Cloudy with scattered flurries over the next 48hrs with up to 6cm before Friday. Alpine temperatures, Low -11 C, High -8 C with gusty SW winds.
