In sintesi

4-6cm are forecast West of the divide, and less to the East. Only isolated areas in the alpine have enough of a slab over the Valentines weak layer to be of concern, but where they exist they will be sensitive to triggering. SH

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 will have a small additional load this weekend.

  • 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

    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.
