Lo esencial

Avoid avalanche terrain. Rapid loading from snowfall and wind is likely to induce a natural avalanche cycle.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–3

    Ongoing snowfall and southerly wind will add to cornices making them weaker and more likely to fail.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    1.5–2.5

    Ongoing snowfall accompanied by southerly winds will add to the storm slab problem throughout the day. The largest and most reactive slabs will be found on lee and cross loaded features on west through east aspects. Strong winds mean that loading could occur further down slope than expected.

Snowpack Summary

Ongoing snowfall accompanied by southerly wind will continue to add to the storm slab problem with the largest being found on west through east aspects. This storm snow will overlie a crust on all terrain except north facing above 1000 m.

Multiple crusts exist in the upper snowpack. Below this is a well settled snowpack.
