In sintesi

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.

    • Sotto il limite del bosco
    Probabilità

    Dimensione

    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

    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.
