In sintesi

Continue to be mindful of the deep persistent slab problem and make conservative terrain choices.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–1.5

    Previous strong winds from the SW have formed thin wind slabs in leeward and cross-loaded alpine features.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

    The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.

Confidence

Moderate

Avalanche Summary

Only isolated size one wind slabs near ridge top have been observed in the last few days.

If you're out in the hills, don't forget to post to the MIN. Every bit of information helps.

Snowpack Summary

5cm of new snow from this past week around Parker Ridge. Upper snowpack comprised of 20-30cm variable density snow sitting on top of the December 17 facet layer. Large facets and depth hoar comprise the bottom portion of the snowpack. Snowpack depths vary from 40-100cm.
