In sintesi

Excellent ski quality out there at the moment! Where features have been sheltered from the wind, you will be rewarded with quality. As you move higher into terrain, wind effect is present and ski quality decreases.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–2.5

    Stiff upper snowpack and/or a drummy feeling should put you on guard for wind slabs. Be on alert as you transition into Treeline features.

  • Deep Persistent Slabs

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

    Thin areas are locations where it is more likely to trigger this weakness.

Avalanche Summary

Forecasters out skiing today with limited visibility did not observe any new avalanche activity, nor was any activity reported.

Confidence

Snowpack Summary

10-15cm over the last 2 days has buried the surface hoar up to 2200m. In most open places at Treeline and above, the wind has eliminated this layer of surface hoar. Wind slabs are widespread in the Alpine and open areas at Treeline, averaging 30 to 70cm thick. This surface wind slab is producing a moderate shear on decomposed crystals at Treeline locations in recent days. If you notice a drummy feel to the snowpack, consider the terrain you are connected to, both under your feet and above you. Stiff wind slabs could travel across a feature and create a large avalanche. The November crust still lingers at the base of the snowpack down 170cm or so and is still a concern for triggering from thinner snowpack areas.

Weather Summary

Monday will see partly sunny conditions with some isolated flurries. A day time high of -9

And the winds, well they will continue blowing in the 40-60km/h range out of the West at ridge top.

Terrain and Travel Advice

  • Keep in mind that human triggering may persist as natural avalanches taper off.
  • Avoid slopes that sound hollow or drum-like.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
