Lo esencial

If 24 hour precipitation amounts exceed  30 cm hazard will increase to HIGH on Tuesday.

Be aware of potential for dry loose avalanches above ice climbs.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2

    Breakable to hard wind slabs are making for challenging skiing and up tracking with new snow.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1.5–3.5

    No avalanches observed on this layer in our tenure however neighboring tenures are still seeing activity. With a large enough trigger this layer could produce results.

  • Loose Dry

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely - Very Likely
    Tamaño
    1–1.5

    30 cm of unconsolidated storm snow will likely move as loose dry on top firm surfaces. Watch for sloughing in steep terrain and be mindful of overhead hazard.
