In sintesi

A significant wind event is forecast to begin on Sunday as the cold air is replaced by a warmer wetter system. The avalanche hazard may rise.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–3
    An specific avalanche cycle occurred today from wind loading on steep (40-50 deg), SE slopes below ridge lines and on cross loaded features between 2600 and 2900 m. Avalanches up to size 3 were observed in this terrain along the Icefield Parkway.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2–3
    Slabs created by previous Moderate W to NW winds overlay weak basal facets. A large load (surface avalanche, numerous skiers on the slope) could possibly trigger this layer.
