Highlights

A cool and quiet day is expected on Thursday.

The avalanche hazard will likely increase on Friday and Saturday as the temperatures are forecast to climb above freezing in the alpine.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2

    Previous winds and new snow have formed isolated wind slabs in lee features in the alpine. Use caution if you move into wind effected snow.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely
    Size
    1.5–3

    A persistent weak layer of facets is down 80–120 cm and may still be triggerable by humans in shallow areas, or by large loads like collapsing cornices.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

No new avalanches have been observed in the last couple days.

Snowpack Summary

Up to 10cm of new snow has been redistributed by previous SW winds, and overlies a sun crust on solar aspects. A thicker melt-freeze crust is found down 20–40 cm at tree line and below. The Jan 24 persistent weak layer is 80–120 cm deep, and mainly a lingering concern in the alpine.
