In sintesi

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

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    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

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    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

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible

    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.
