    • Sous la limite forestière
    Probabilité
    Possible

    The majority of the windslabs are bonding well, but there remains the potential to trigger isolated slabs in steep, wind loaded areas in the alpine. Assess terrain cautiously.
  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité

    Large temperature swings from -20 at night to +2 during the day has us in a melt freeze cycle on south aspects. Steep south alpine slopes continue to release naturally in the afternoon.
  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière

    Solar radiation has led to small Loose snow avalanches starting in the high alpine and stepping down into the basal facets on solar aspects. Cornice failure on NE aspects could also step down into the basal facets.
