Weather Forecast
Snowfall amounts tapering off steadily, with only light scattered flurries expected through to the weekend. Temperatures will continue to cool, dipping down to -15C in the alpine. Winds decreasing and returning to the light range, gusting moderate from the Southwest.
Snowpack Summary
5-10cm of new snow has been pushed around by recent moderate SW winds, forming new windslabs in the alpine. This new snow covers a couple interesting surface hoar layers in the top portion of the snowpack - Jan 7 (5-10mm well preserved) and Jan 17 (2-5mm). These layers may present a touchy interface for new windslabs and storm snow.
Avalanche Summary
Limited visibility, but field teams report several natural slab avalanches to sz 2, originating in the alpine and running to the bottom of the track. The Jan 7 surface hoar layer was reactive to skier traffic, and ski cutting produced numerous sz 1 wind slabs in the Hilda Creek area. More activity is expected on the Jan 7 layer over the next while.
