Lo esencial

Monitor the degree of overnight freezing as it relates to how quickly afternoon temperatures will have a destabilizing effect on the snowpack. It is the time of year to get an early start and be back in time for afternoon siesta.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Southwest winds continue to build windslabs and cornices on Northerly aspects. Recent avalanches have started from rock bluffs or cornice failures and have triggered deeper weak layers.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    2–4
    The buried surface hoar layer 50-120cm down remains a concern in areas that have not avalanched. Whumphing is still being observed on North shaded glades below treeline. Be cautious of this layer as triggering it would be high consequence.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3
    With extended sunny periods, expect to see loose snow avalanches originating from steep rock bluffs or gullies. Ice climbers need to start and end early.
