Lo esencial

Travel with caution when exposed to large overhead hazard.  The weak basal layer has potential to create large scale avalanches.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Wind slabs exist on all aspects but tend to be thicker on easterly aspects. These may be up to 50cm thick in heavily loaded areas.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    2–3
    This hard slab is spotty in nature. Expect to see it start near treeline and carry on higher. If it does react, it will likely propagate for a long ways.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–4
    Past avalanches have stepped down to this layer. Thin areas and transitional terrain remain a concern.

Snowpack Summary

We have up to 20cm of recent snow.  This snow has minimal wind effect below 2500m and overlies a temperature crust on all aspects below 2100m and up to 2300m on solar aspects.  A  strong mid to upper pack overlies a weak base at all elevations. The weak basal facets and depth hoar make up the bottom 70cm of the snowpack at all elevations which gives us little confidence in large terrain if an avalanche is triggered.
