While the snowpack remains very thin for this time of the year, be wary of venturing into deeper areas where wind deposition has developed slabs over a weak base.
Early Season Conditions persist.
Little change will occur with conditions until winds pick up on Monday.
No new avalanches were reported or observed on Saturday.
A size 2.5 avalanche in Redoubt Bowl near Lake Louise slid on the October crust/facet layer earlier in the week.
Thursday's storm snow has settled to 10-20cm and is distributed in an upslope pattern. Only trace accumulations are found west of Castle Junction.
This snow overlies a previously wind-scoured snowpack with a suncrust on south and west aspects.
The bottom of the snowpack consists of weak basal facets that are associated with crusts in some locations.
The snowpack is 30-50 cm deep at treeline with many areas below threshold. 40-80 cm at most in the alpine.
Light north winds will persist Sunday as some cloud cover develops. Temperatures will cool a bit with treeline highs reaching -10C and valley bottom lows as cold as -20C overnight. Alpine temperature inversions are likely.
Winds are forecast to shift to the west late Sunday and increase into the strong range through Monday.
