Lo esencial

Two systems will give us small amounts of snow tonight and Saturday, slowly adding load to the Valentine's surface hoar. This layer is touchy, and one should use caution in areas of fresh wind slabs, particularly in the alpine.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    The 10-15cm of storm snow we received 3 days ago has formed small slabs in the immediate lee areas of ridges. These slabs are touchy as they lay on top of the Valentine's surface hoar. A skier-triggered sz 1.5 occurred near Quartz Ridge yesterday.

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–3
    Large cornices on lee (mostly easterly) aspects still loom high overhead. Several large cornice collapses have been observed over the past week. These cornices could be big enough to trigger a deep slab.
