In sintesi

Assess your line very carefully and be mindful for rocks and vegetation buried under the new snow.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Multiple wind slab layers at the top of the snowpack can be triggered and may step down to the deeper instability at the bottom of the snow pack.
  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Up to 30cm of new storm snow is not yet bonded to the old snowpack.
  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    2–3
    Triggering this layer from a shallow area is possible and would have high consequences in terrain features of any size.

Weather Forecast

A return to colder conditions and only a few centimeters of snow is forecast for the next few days. This will do little to change the current avalanche conditions.

Snowpack Summary

Up to 30cm of new storm snow now overlies existing wind slabs. Strong supportive mid pack at TL and above lies on a very weak faceted basal layer. Below tree line the snow pack has very little support except in isolated open areas where wind slabs may exist.

Avalanche Summary

Road patrols in the forecast area observed a size 2 storm slab at TL and sloughing from steep south facing terrain.
