    Strong westerly winds today and yesterday redistributed Sundays storm snow and formed fresh wind slabs in the alpine and treeline elevations. Conservative decision making is required on wind affected slopes.

    There is still concern for riders hitting the weak spot and triggering a full depth release on basal facets. A rider triggered a size 2.5 avalanche on this layer in the Lake Louise backcountry on Sunday. See the facebook link below for pictures.
