In sintesi

A widespread natural avalanche cycle is likely with unseasonably warm temperatures and high freezing levels. This is a good weekend to avoid avalanche terrain.

Problemi valanghivi

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1.5–3.5

    This layer is likely to become more reactive with rising freezing levels this weekend.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Very Likely
    Dimensione
    1–2.5

    Small wet loose avalanches could trigger persistent weak layers and result in large avalanches.

Terrain and Travel Advice

  • Avoid exposure to overhead avalanche terrain as temperatures increase.
  • Persistent slabs have potential to pull back to lower angle terrain.

Confidence

Moderate

Avalanche Summary

Numerous natural wet loose avalanches have been observed on solar aspects at all elevations. One natural, size 2 persistent slab avalanche was observed on Thursday, likely triggered by solar input and increasing temperatures.

Snowpack Summary

Moist surface snow all elevations on solar aspects. The Feb 3rd crust/facet persistent weak layer is buried 60-120 cm deep. Below this, the snowpack consists of a mixture of settled snow and crust/facet layers to ground. Snowpack depths between 80 - 250 cm.
