Kernpunkte

A widespread avalanche cycle has been caused by the recent storm overloading the basal depth hoar. Another storm Friday will keep the danger HIGH.

    Strong westerly winds with the storm have created thick soft to hard wind slabs in all open areas that are easily collapsing on the basal depth hoar and increasing the propagation width of the resulting avalanches.

    A 40mm storm with strong winds has doubled to tripled the total season snowpack over the last 36 hrs. Natural and human triggered avalanches up to size three are occurring throughout the forecast area failing on the basal depth hoar.
