Regions
Northwest Inland.
The best riding is likely to be found on sheltered north and east facing slopes.

Avalanche Summary
No new avalanches were reported in this region on Wednesday. However, east of Ningunsaw Provincial Park, evidence of an old cornice triggered size 3 persistent slab avalanche was reported on an easterly aspect that failed on facets around 100 cm down at 2100 m.
Snowpack Summary
Expect to find sun crusts on steep solar aspects. The old wind slabs created over the weekend are faceting and becoming less reactive to human triggers.A crust/surface hoar layer buried mid-January is now roughly 80-140 cm below the surface, and still has the potential to be triggered from a thin snowpack spot, or with a large trigger like a cornice fall.It is unlikely, but may still be possible to trigger very large avalanches on facets at the bottom of the snowpack in steep, rocky, and shallow snowpack areas or with large triggers.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
