In sintesi

Keep an eye on localized conditions. If more snow falls than is expected, some areas could see a rise in avalanche danger to Considerable.

  • Wind Slabs

    • Alta quota

    • Sotto il limite del bosco
    Probabilità

    Dimensione

    Wind slabs are dominant in Alpine and Treeline terrain. Very little natural avalanche activity has been occurring, but human-triggering is more likely.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

Tuesday will be cloudy with scattered flurries. Snowfall accumulations could reach 10cm by the end of day Tuesday with a further 5cm on Wednesday. Temperatures tomorrow will start out cold and then climb to  -6 °C with moderate SW winds.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Moderate to strong SW winds combined with warm temperatures have added to the already widespread wind slab conditions in the Alpine and at Treeline. These slabs exist on all aspects, except in some specific windward terrain where the wind has stripped the snow down to bare rock. The Dec 15th interface (surface hoar on north aspects, sun crust on solar aspects) continue to produce results in snowpack stability tests. The November and October crusts deeper in the snowpack continue to facet and forecasters are watching these layers as a potential future problem.
