Regions: Boundary, Howson, Kitimat, Nass, Northwest Coastal, Rupert, Seven Sisters, Shames, Stewart.
Carefully assess steep lines for wind slab. Wind slab could still be rider triggerable near ridge crests.
Confidence
Moderate
Avalanche Summary
A wide spread natural avalanche cycle occurred earlier this week during the storm. Since then avalanche activity has tapered off with only small explosive triggered avalanches reported on Wednesday.
Snowpack Summary
Wind slab can still be found on northerly aspects from previous southerly winds. At lower elevations a new crust has likely formed on all aspects.
The mid pack contains several crusts from November. In general the mid pack is well settled.
The snowpack depth is approaching two meters in the alpine but is still quite shallow below treeline.
