In sintesi

On Friday a ridge of high pressure will bring light wind and sunny skies. On Saturday a pacific frontal system will bring light snowfall (10-15 cm). The hazard is not expected to change much unless snowfall amounts are higher then forecasted.

    A well settled midpack overrides a weak facetted base. This weak base is found most places except the west side of the divide. Beware of steep shallow snowpack areas (where the likelihood of triggering this basal layer is highest).
