Avalanche Summary
A few small natural wind slabs were reported in steep south facing terrain west of Smithers on the weekend. Wind slabs showed some reactivity to human triggers last week, but cold temperatures have generally made them difficult to trigger.
Snowpack Summary
Surface snow has been affected by winds from a variety of directions. The degree of wind effect varies throughout the region, with the most dramatic winds associated with outflow conditions in the western parts of the region near coastal inlets. Sheltered areas may still have 10-30 cm of powder from previous storms. A variable weak layer can be found roughly 20 cm below the surface, but in most places insufficient snow has fallen for it to be reactive. The layer comprises of crusts on solar aspects and feathery surface hoar crystals in sheltered locations.The lower snowpack is generally well settled with two prominent crusts. The late November crust can be found 30-50 cm below the surface and the October crust is near the base of the snowpack.
