Lo esencial

Moderate to strong winds continued in the alpine through today but from the north; expect to encounter some reverse loading of south and east facing features at ridgecrests and tree fences.

    Windslabs are present in sheltered lee features at Treeline, mostly near ridge tops and protected pockets in the Alpine. The past warm temperatures are helping them bond to older snow surfaces.

    Basal facet collapses are still being noted below midpack bridging layers. Shallow snowpack areas and rocky outcrops are likely trigger locations.
