Avalanche problems

  • Wind Slabs

    • Treeline
    • Below treeline

    Size
    1–4
    Wind slabs are found in Alpine areas on lee and cross-loaded features. In most areas these slabs sit on a crust. Take the time to evaluate the bond of the wind slabs to the crusts below.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size

    Solar aspects are susceptible to increasing avalanche danger each day as solar radiation affect the snowpack. Plan your day to avoid exposure to large sunny slopes in the afternoons.

Confidence

Fair - Intensity of incoming weather is uncertain on Monday

up to 5cm HN in alpine areas that has ben redistributed by moderate to strong NW winds. New windslabs suspected in isolated terrain, but for the most part the storm snow has been blown clean. A thick and supportive melt/freeze crust is exposed up to 2500m. Isothermal snow below treeline by early afternoon, even with heavy cloud cover. Compression tests on a windward aspect had moderate results on a crust down 28cm on depth hoar, 2440m.
