Points saillants

People have been getting after it in the mountains, and have certainly been testing the stability. It is good for Feb, but not exceptional. 5-10cm of snow Monday evening (E. of divide) will start to bury the surface hoar which is widespread. SH

Problèmes avalancheux

  • Wind Slabs

    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    2–3
    Isolated wind slabs in the high alpine are still triggerable in steep terrain. Thinner snowpack areas in steep, gully sidewalls and unsupported slopes will be most vulnerable.

  • Cornices

    Taille

    Strong winds from earlier in the month have created large cornices on lee (mostly easterly) aspects. Several large cornice collapses have been observed over the past week. These cornices could be a big enough to trigger a deep slab.
