In sintesi

Observations of several large avalanches in the last 48 hrs from very steep alpine terrain indicate the possibility of a basal release still exists. A gradual warming trend with precip and stronger winds for Sat. will increase hazard for the weekend

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Thin windslabs exist at treeline and in the alpine. These will facet out with the forecasted cold temperatures, but may be triggerable by riders in the next few days. An avalanche on this layer may be enough to step down to the basal facets.
  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3
    Cold temperatures are facetting a well settled midpack which overrides a weaker facetted base. This weak base is found most places except the west side of the divide. Many thin spots exist in the alpine and treeline due to previous strong winds
