Human-triggered wind slab is the main concern.
The best and safest riding will be on slopes that have soft snow without any slab properties.
Additional snowfall and wind are continuing to build wind slabs. Expected them to be reactive to human triggers, especially in freshly wind-loaded terrain features.
Field observations remain limited, with poor visibility restricting observations over the past few days.
Besides some sluffing in steep terrain, there have been no reports of avalanche activity in recent days, despite the accumulating storm snow.
In neighboring regions to the north of Highway 16 and to the south of Kinbasket, large (size 2+) wind slabs have been observed on north to east aspects at upper elevations, triggered both naturally and artificially.
40 to 80 cm of recent snow overlies a prominent hard crust formed in mid-December that extends up to 2200 m. Continued wind has redistributed the recent snow in exposed terrain at treeline and in the alpine.
Where the crust is thick and supportive, it effectively caps a few of the mid-snowpack instabilities, making them difficult to trigger. These include a spotty surface hoar layer and a crust/facet layer from mid-November. These layers may still be a concern in the high alpine, where the crust is thin or nonexistent.
Snowpack depth is around 160 cm at treeline, tapering with elevation below 1500 m.
