Points saillants

Scattered flurries with moderate winds should not affect the danger level drastically in the next 2 days. The sun, however, is packing quite a punch on solar aspects at tree-line and below. Pay attention to this warming as you return to the valley.

Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–3
    The Valentines surface hoar down 70-150cm is bonding well to the surfaces above and below. Test results are finding hard to no results on this layer. The chance of triggering will increase in thinner areas, and large avalanches are still possible.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille

    Although difficult to initiate, it is still possible to trigger a deep persistent slab. Heavy loads in steep and shallow areas are the most likely trigger to produce an avalanche on this layer currently.
