Lo esencial

A natural avalanche cycle to size 3 is occurring, and the spike of this system will happen early tomorrow. We may dip into extreme during this time. 48hr. snowfall amounts so far 30cm to 70cm, and rain in Field and Kootenay, 30 cm more possible.SH

Problemas de aludes

  • Wind Slabs

    • Alta montaña

    • Bajo el límite del bosque
    Probabilidad
    Likely - Very Likely
    Tamaño
    1–3
    Fresh and buried wind slabs up to 60cm thick are primed for triggering. They have been seen to step down onto the Valentines surface hoar layer to cause larger avalanches.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely - Very Likely
    Tamaño
    2–3
    Snow depths over the Valentines surface hoar and sun crust on steep solar aspects range from 40cm E of the Divide, to 90+cm at Sunshine and Yoho. Continuing warm, dense snowfall and strong winds will increase natural activity on this layer.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Recent trips east of the Divide have found a shallow, weak snowpack. Tests done showed sudden collapse results on the basal facets. It is still possible to trigger the entire slope from shallow, thinly covered areas.
