Lo esencial

It is getting harder to trigger an avalanche on the Valentines surface hoar, but the consequence of triggering one is huge. Areas West of the Divide have more bridging strength overall. Watch for triggering from thinner areas.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Isolated wind slabs up to 50cm thick can be still triggered in steeper terrain, especially around ridge crests.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    2–3
    Down 70-120cm, the Valentines surface hoar is producing harder shears, and Field teams in Yoho, the Wapta, and Kootenay today had similar results. A size 3 triggered by seracs in the bow hut area remote triggered moraines on this layer yesterday.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3
    Numerous steep solar slopes were reported to slide today up to size 2.5 in the Emerald Lake area. Tomorrow we may see the same occurring. Failing cornices in the sun may provide a large trigger.
