Points saillants

Our message of caution remains the same: Deeply buried weak layers may be hard to trigger, but if they are triggered large avalanches could result. This is not the time to ski/ride big features.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille

    Wind slabs are widespread on lee and cross-loaded features at Treeline and above. Use caution is steep, convex and unsupported terrain, and be wary of shallow snowpack areas.

  • Persistent Slabs

    • Limite forestière

    Avalanches could step down to the basal October layers and involve the entire winters snowpack. Wide propagations are possible. Shallow snowpack areas are a potential trigger point.

Confidence

Good

Weather Forecast

Wednesday will be mostly cloudy with temperatures near -5 degrees. Winds will be light at ridge-top. Unfortunately , the previously forecasted snowfall is now completely gone from the weather forecast. Only light flurries are possible on Wednesday and a trace of snow is expected Thursday.

Avalanche Summary

Nothing new.

Snowpack Summary

Sun crust on South and West aspects at all elevations. Surface hoar continues to grow in sheltered areas below treeline. Wind slabs are widespread at treeline and above. Basal weak layers persist, with snowpack stability tests (Compression Tests) indicating failures in the basal facets.
