In sintesi

Weak layers in the snowpack are not healing. Conservative route choices are required.

Problemi valanghivi

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1.5–3
    Slabs are everywhere in lee and cross-loaded terrain in the Alpine and open areas at Treeline. These slabs are very sensitive to human-triggering in steep and unsupported terrain.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–3
    The basal layers are very weak. An avalanche initiated in the upper snowpack could step down to the bottom of the snowpack.

Avalanche Summary

No new avalanches observed today.

Snowpack Summary

Wind slabs are widespread in the Alpine and at Treeline in lee and cross-loaded terrain. The Dec 10th surface hoar/facet interface is prominent throughout the forecast area and continues to produce easy to moderate shears down 40 to 60cm. The basal layers are very weak and facetted, with occasional ski penetration to ground when you leave the up-track.
