In sintesi

Thin wind slabs are building in the Alpine, but these are not yet enough to tip the scales to a higher danger rating.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione

    Strong winds and recent snowfalls have created thin wind slabs in Alpine terrain. These will continue to build through Sunday.

  • Persistent Slabs

    The December rain crust is still possible to trigger down 30 to 50cm at 2200m. Recent stability tests indicate failures at this interface in the moderate range.

  • Deep Persistent Slabs

    The widespread basal weakness is still a concern in the snowpack. Avalanche observations last week indicate that full depth slides are still a possibility.

Confidence

Good

Weather Forecast

Sunday will remain cool with moderate NW winds and significant wind chill. Trace amounts of precipitation are expected. Monday and Tuesday will see slight warming and very light flurries.

Avalanche Summary

Nothing new but visibility was extremely limited today.

Snowpack Summary

5 to 10cm of new snow overnight is forming thin wind slabs in Alpine areas. The December rain crust is present below 2250m on all aspects and is still reactive in stability tests. The basal facets are alive and well, and will remain an issue for some time to come.
