In sintesi

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

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–3
    Cross-loaded gullies and ridgeline features will be especially sensitive to human triggering.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2
    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

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    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
