In sintesi

A widespread weak faceted base is the root of all concern. Be very cautious in all steep terrain for slab and loose snow avalanches.

Problemi valanghivi

  • Wind Slabs

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

    A SW wind event produced touchy wind slabs in lee and cross-loaded terrain at tree line and above.

  • Loose Dry

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

    Loose dry avalanches should be expected in steep terrain, and may entrain significant amounts of snow in gully features.

Weather Forecast

Clear warm conditions with light winds expected until Tuesday night then there is the potential for some snow (up to 10 cm) with moderate SW winds.  (Don't hold your breath)

Snowpack Summary

SW (M-S) winds have built slab on top of a weak faceted snowpack on exposed tree line and alpine features. Mid-pack starting to loose strength.  Very weak faceted snowpack below tree line.

Avalanche Summary

A couple of sz 2.5 slab avalanches in the alpine (a cornice and natural) on south and NE aspects south of the Icefields along the Parkway observed on Saturday.

Confidence

The weather pattern is stable on Monday
