Points saillants

An incoming storm will bring new snow, warm temps and increased winds.

As the storm progresses the avalanche danger will rise.

Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2.5

    20-50cms of snow overlays a buried persistent weak layer. This weak layer consists of surface hoar, facets and/or a suncrust. It will be most reactive where there is a settled, cohesive slab on top of a crust.

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Likely
    Taille
    1–2.5

    Fresh snow and moderate to strong winds will be creating a new slab. This will be sitting on (yet another) weak layer of facets, expect this to be most reactive in immediate lee features. As the storm progresses the storm slab will become more widespread and reactive.
