Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    2–3
    The Mid February buried surface hoar layer continues to produce dramatic sudden planar test results. This layer will be hard to trigger but if it does expect large destructive avalanches.

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    2–3
    Variable winds in alpine areas continue to form slabs on lee aspects. We've seen 70+cm of new snow since March 12th. Steep northerly terrain in the alpine is the biggest concern.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely

    As the spring season arrives even short periods of direct sun can have dramatic effect on the snow stability on solar aspects. Watch for increased loose snow avalanche activity during the heat of the day.
