Reactive wind slabs near ridgelines and rollovers will continue to develop. Choose sheltered slopes where the recent snow has not been wind-affected.
Reactive wind slabs are expected to form as the wind keeps transporting new snow. Rider-trigger is possible around leeward terrain features, especially at treeline, where a preserved layer of surface hoar has been observed.
A few natural avalanches (up to size 2,5) were reported near Ningunsaw, but very limited visibility restricted other observations elsewhere in the region. If you do go into the backcountry, consider submitting a Mountain Information Network report.
15-25 cm of new snow has fallen over the last few days. Strong southerly winds had likely redistributed it at higher elevations, leaving exposed areas scoured. Under this new storm snow, a weak layer of surface hoar is showing signs of reactivity.
The snowpack remains generally shallow, with early-season hazards just below the snow surface. A weak layer of faceted snow may be present at the base of the snowpack. The height of snow at treeline is approximately 50-100 cm.
A large and impactful weather system will continue to bring light precipitation and windy conditions to the region. High-freezing levels are expected until mid-week.
