Large avalanches may run into below treeline. Time to avoid all avalanche terrain.

Avalanche problems

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–3.5

    With the warm temperatures and freezing level we expect this deep layer to wake up and cause large destructive avalanches.

Confidence

High

Snowpack Summary

The snow surface likely consists of a mix of hard melt-freeze crust and dry snow depending on aspect and elevation. Sun-exposed slopes may undergo daily melting and freezing whereas northerly alpine slopes could remain dry with potential slabs.

The Feb 3rd crust is the dominant mid-pack layer and make reawaken under periods of intense, prolonged warming or rain.
