Avalanche problems

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    3–4
    Cornices are starting to fall off ridges providing a large trigger for slopes below. Some of these giants have enough weight to initiate large avalanches that could step down to deeper weak layers and run full path.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–3
    Many loose, wet avalanches today on all aspects to size 3 below 3000m. starting in the afternoon. Tuesday should have less solar input, but with little freeze it wont take much to increase the hazard.
