Lo esencial

The winter that keeps giving. 20cm of new snow by tomorrow. There has been just enough spring-like weather to create crusts on solar aspects, but not enough to create the usual bomber spring snow pack. Travel as though it is still winter!

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    New wind slabs are forming in the alpine and at tree-line, on top of the storm snow slabs formed the last few days. These slabs can be easily triggered and may result in an avalanche stepping down to deeper weaknesses.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–4
    The Valentines surface hoar layer and the weak basal depth hoar have both been sliding layers for large avalanches over the last several days. Steep unsupported slopes, thin rocky areas and steep solar aspects are the most likely areas to trigger.
