Ridgetop winds are forecasted to pick up over the next few days, although previous winds have already moved much of the available snow. Pay attention to wind loading as you make your way into the alpine and continue to make conservative terrain choices.
Past winds have created wind slabs in alpine and some exposed treeline locations. Incoming strong winds over the next few days may add to these but there is not a lot of snow left to move around in much of the terrain. Caution in steeper lee terrain is advised.
The bottom layer of the snow pack is facetted and weak. Human triggering of this deep persistent layer is possible.
Lake Louise Ski Area reported triggering some small windslabs in alpine terrain with explosives on Tuesday. Otherwise, no new avalanches observed or reported.
Previous SW winds have created wind slabs in the alpine and exposed treeline locations. Below this is a semi-supportive mid-pack that may include a raincrust (1-7 cm thick) that exists up to 2300m. The lower snowpack is facetted and weak.
Light flurries with minimal accumulation are forecasted along the continental divide through Friday. Ridgetop winds will be SW, moderate to strong on Wednesday, picking up to strong to extreme on Thursday, and then easing slightly to strong on Friday. Temperatures will be relatively mild with freezing levels near valley bottom.
