Lo esencial

The forecast calls for a stable weather pattern in the next few days.

Problemas de aludes

  • Wind Slabs

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    15-30cm of new snow combined with southwest winds have created deeper deposits in lee terrain in the alpine and tree line.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–3
    A weak layer buried around 50 to 100 cm is still the main concern. Although avalanche activity has been quiet for the past week, the widespread nature of the layer and snowpack test results suggest that it is still a layer to be concerned about.

Avalanche Summary

Recent reports from Saturday indicate widespread thin storm slab avalanche activity size 1-1.5 that were 15cm deep with a some avalanches running to size 2 where thicker wind deposits existed (up to 40 cm). These were reported as explosives triggered, naturally triggered and some skier controlled.

Snowpack Summary

20-40 cm of snow sits on a thin sun crust on southerly aspects and small feathery surface hoar in sheltered areas.Beneath this, around 50 to 100 cm of snow sits on a rain crust and a weak layer of feathery surface hoar and sugary facets. Although there has not been a reported avalanche on this layer in over a week, snowpack test results tell us that it is still possible to trigger. The lower snowpack is well-settled.
