Points saillants

As one of our forecasters said, stability is good but not "yahoo good". It is still only early February and a low danger rating does not preclude the triggering of isolated wind slabs the alpine.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–3
    Field observations show wind slabs still exist at higher elevations (above 2800m) on the lee side of alpine ridges.

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    2–3
    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 trigger to trigger a deep slab.
