Highlights

New snow has finally arrived! Great skiing can likely be found, but the avalanche hazard has increased in many areas, and you still need to watch out for those early season hazards.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1–2.5

    Strong south west winds have, and will continue to form wind slabs in leeward and cross-loaded terrain features at tree line and above.

  • Loose Dry

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1–2

    Use caution in steep and/or confined terrain features.

Snowpack Summary

10 to 25cm of storm snow now sits on a significant weak layer combination of facets, surface hoar, and various crusts. Strong south west winds have redistributed this snow into wind slabs on leeward and cross-loaded terrain features in open areas at tree line and in the alpine. The height of the snow at tree line ranges from 50 to 90cm.

Confidence

Moderate
