Kernpunkte

Cautious route finding and conservative terrain choices are required with the unpredictable snow conditions.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible - Likely
    Größe
    1–3
    Cross-loaded gullies and ridgeline features will be especially sensitive to human triggering.

  • Storm Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze

    Storm slabs may be present especially at tree-line. If triggered, it is likely it will initiate the rest of the weak faceted snowpack.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze

    Isolated locations where this layer is persisting. Has morphed into depth hoar in many areas.

Weather Forecast

No forecasted precip, light SW winds and cooling temps into the weekend.

Snowpack Summary

New transported HST building developing wind slabs in the ALP on N to E asps. At TL, soft slab and wind slabs in open areas over a faceted midpack to depth hoar. Nov crust in isolated areas; deeper, sheltered north aspects. Thin rain crust BTL on all aspects below 1600m. Loose point releases from steep un-skiable terrain at all elevations.

Avalanche Summary

No avalanches reported or observed.

Confidence

Due to the number and quality of field observations
