In sintesi

Warming temperatures with the possibility of rain showers forecast for this weekend could increase the avalanche danger below treeline. Pay close attention to abrupt changes in temperature and precipitation type if traveling in avalanche terrain.

    The alpine is mostly blown bare with hard windslabs and loaded lee slopes that can be easily identified and avoided. Wind slabs are present on easterly treeline aspects. These can be a little more tricky to identify so avoid slabby feeling slopes.

    Basal facet collapses are still occurring below the midpack bridging layer. Shallow snowpack areas and rocky outcrops are likely trigger locations. A large full path avalanche could result if this weakness is triggered.
