Kernpunkte

Scattered flurries and moderate west winds are forecast for the remainder of the weekend. Only isolated areas in the alpine have enough of a slab on top of the Valentine's weak layer to be a concern. They will be sensitive to triggering where present

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    The Valentines surface hoar, facets will be buried anywhere from 5 cm - 30cm where drifted in on the immediate lees of ridge crests. These wind slabs will be thicker West of the divide and have received a small additional load today.

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–2
    Large cornices on lee (mostly easterly) aspects still loom high overhead. Several large cornice collapses have been observed over the past week. The volume of cornice debris would be very detrimental to your day.

  • Loose Dry

    In steep areas mainly West of the divide, watch out for new snow sloughing on surface hoar, facets or suncrust on steep solar aspects. This will increase with additional new snow.
