Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Strong westerly winds have created 10-30cm soft slabs. Whumping was observed near treeline and several class 1.5 - 2 soft slab avalanches were recorded from the past 24hrs.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely
    Size
    2–4
    Increase loads with wind or new snow may awaken this instability. Size 2 surface slab avalanches may step down to this layer producing much larger avalanches.
