    Wind slabs 20-50cm thick in wind exposed areas from recent SW winds. These seem to be isolated to lees of terrain features and ridge crests.  Reports are finding these wind slabs to be sitting on a thin layer of facets formed in early Dec.

Weather Forecast

Increased SW to SE winds Sunday with continued cool temperatures and some light snow in regions South of the Trans Canada Highway.  Winds will abate by Sunday night and we should see cold and clear conditions Monday.

Snowpack Summary

A field trip to Yoho  found soft wind slabs (4 finger) near ridge crests 20cm thick.  These were buried by 10cm of low density powder. Reports of stiffer wind slabs in wind exposed terrain. Low density powder in sheltered features. Thicker snowpack areas have mainly well settled midpack. The Nov.6 crust is mainly now a facet layer in thinner areas.

Avalanche Summary

No avalanches observed or reported today. 

Confidence

Wind speed and direction is uncertain on Sunday
