With clear skies, expect to see some increased avalanche activity on solar aspects in the afternoon.

Problèmes avalancheux

    Last week's snow was distributed by mostly moderate to strong winds into windslabs and cornices on North through Southeast aspects. Recent avalanches have started from rock bluffs or cornice failures and have triggered deeper weak layers.

  • Persistent Slabs

    • Alpin
    • Limite forestière

    The buried surface hoar layer remains a concern in areas that have not recently avalanched. Solar effect will weaken the bridging strength of the slab on exposed slopes.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité

    Expect to see small avalanches on steep solar slopes at lower elevations by noon. Ice climbers should consider these small avalanches if climbing on south through west facing climbs.
