Kernpunkte

With forecasted warm valley bottom temps and rain, treat any slope below 2000ms with caution for wet loose slides.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Building windslab at tree line and above on lee aspects. It's a continuous problem that requires constant attention in order to ensure your safety and riding quality.

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Large cornices on ridge top lee features. Their sheer mass is a problem. Recent cornice failures have been generally small (a few tons or so;) but are consistently triggering large deep persistent slab avalanches in alpine terrain.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    2–4
    The deep persistent slab can be triggered by travelers from shallow or weak locations or naturally from large loads such as cornice failure or windslab avalanches.

Weather Forecast

Light precip forecasted over the night Wednesday. Expecting no more than a trace of new snow. Ridge tops temperatures to a high -3 °C. Light westerly winds through the day.

Snowpack Summary

Creamy and settled surface snow with some wind effect in the open. Near surface non-persistent weaknesses, active on typically problematic features like convexities and immediate lees. Interfaces dwn between 60 and 100cms though the mid-pack with inconsistent mod to hard field test results. All this, sitting on a large, facet layer off the ground.

Avalanche Summary

No new activity seen or reported today.
