Kernpunkte

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.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    Isolated wind slabs up to 50cm thick can be still triggered in steeper terrain, especially around ridge crests.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    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

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe

    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.
