Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    Recently developed wind slabs have gained considerable strength, but may be triggered in steep, isolated terrain.

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–6
    Cornices are reported to be very large and potentially unstable at this time. A cornice fall could be destructive by itself, and may also act as a trigger on the slope below.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–3
    Loose wet avalanches are likely on steep sun exposed slopes in the afternoon.

Confidence

Fair - Due to variable snowpack conditions

Snowpack Summary

Moderate to strong southeast winds have recently created wind slabs that have now gained considerable strength. Solar aspects are now moist under sunny skies during the day with a good crust recovery developing at night. Surface hoar or facets may exist in some parts of the region of the region between 60 and 120cm deep. There has been no recent activity on these layers but they could wake up with heavy triggers like a large cornice chunk or a snowmobile digging its track in. Cornices in the region are reported to be very large and potentially unstable.
