Lo esencial

Remain vigilant in steep and unsupported terrain in case you find the sweet spot for that wind slab, or triggering a deeper slab in a shallow snowpack area. Otherwise, we need some more snow before the danger level will rise.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–2
    Wind slabs are present in the Alpine on all aspects, and in isolated spots at Treeline. Steep and unsupported terrain are areas where triggering is more likely.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely
    Tamaño
    2–3
    Triggering of a deeper slab is unlikely, but still possible in shallow snowpack areas.

Weather Forecast

The cold temperatures will continue until Sunday, so be sure to bundle up. Thursday will be cloudy with sunny periods and isolated flurries, but very little accumulation is expected. Temperatures will climb to -15 °C in the Alpine, but likely be colder in the valley floors. Wind chills will remain a factor with light to moderate westerly winds through the period.

Avalanche Summary

A few loose dry avalanches up to size 1.0 in steep Alpine terrain on all aspects.

Snowpack Summary

The snowpack continues to facet with the persistently cold temperatures. Wind slabs are found in Alpine areas on all aspects, and in isolated spots at Treeline. Below 2200m a buried layer of surface hoar (down 20 to 30cm) remains a layer of note, but due to the current lack of an overlying slab this layer has not been active. Deeper in the snowpack the November and october crust layers are being monitored, but are not currently active.
