Highlights

The avalanche danger in the morning will be determined if there was a freeze and how strong the crust developed. Temperatures are expected to stay warm so evaluate your trip based on the crust and start early.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    Sunday's rain soaked into the recent storm snow adding more load to windslabs. This may contribute to natural and skier initiated avalanches at all elevations.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    If freezing levels remain at mountain top elevations, expect to see avalanches where rainfall has soaked into the upper layers of the snowpack.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–4
    Warm temperatures and rain may contribute to cornice fall which could overload these weak layers contributing to full depth avalanches.
