In sintesi

Cool temperatures will persist until Friday, but the weekend should bring more seasonable weather. Some light snowfall will begin on Friday and into the weekend. The avalanche hazard is not expected to change much over the next few days.

    Strong valley bottom winds from the east and moderate south westerly winds in the alpine have created soft slabs in immediate lee terrain. Cool temps should break these slabs down, but for the short term be wary of lee terrain in open areas.

    A well settled midpack overrides a weaker 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).
