    While skiier triggered sluffs may be possible in some areas if adventuring into very steep, shaded terrain, minimal natural activity is expected.  If any, it will be isolated to steep sunny slopes during the afternoons.

Snowpack Summary

2-5cm new snow Thursday night, with Moderate SW winds, has generally had little affect on the snowpack.  Isolated small windslabs could, however, exist in Maligne area.  The upper snowpack remains faceted; sluffing in steep terrain may be possible with ski traffic or strong sun. A strong midpack overlies the (dormant) basal weakness.
