In sintesi

Wind slabs are developing above treeline, and the deep persistent problem remains a low‑likelihood but high‑consequence concern.

New snow is beginning to improve skiing conditions.

Problemi valanghivi

  • Wind Slabs

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

    New wind slab are forming from recent snow and strong southwesterly winds. These will be found in lee features and sit above a weak layer of facets or surface hoar.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3.5

    This problem is low probability but high consequence as it would be releasing near the ground thus with a lot of destructive volume. Be extra cautious where snowpack goes from thick to thin areas.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches observed or reported in the region.

Snowpack Summary

Ten to 15 cm of new snow sits above a weak layer of surface hoar and facets. This weak layer is more problematic in areas of wind loading. In exposed areas, recent winds have redistributed the new snow into windslabs. The midpack is dense and supportive in most areas. At the bottom of the snowpack, the weaker, more facetted layer above the ground creates a deep persistent slab.

Weather Summary

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
