Highly variable upper snowpack requires cautious terrain evaluation at all elevations.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–2
    Watch for reverse loading with recent N-E Winds.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2.5
    Recent snow has been enough to create a  windslab over deep instabilities below treeline where the snowpack is shallow and weak, and melt freeze crusts have been preserved.

Snowpack Summary

The upper snowpack is highly variable with a variety of Windslab and Wind affect in all but the most protected areas. The midpack remains strong in deep snowpack areas, but is acting as a slab above deep weak layers in shallower areas that is reactive skiers mainly at below treeline elevations where melt freeze crusts have been preserved.

Avalanche Summary

No new avalanche activity observed in the past 24h.

Confidence

Wind effect is extremely variable
