Windslabs can be found on all aspects from variable winds, be cautious when you transition into wind-affected snow.
Northerly outflow winds formed wind slabs on south-facing slopes on Thursday, while continued westerly winds may now form new wind slabs on east- and north-facing slopes. Be cautious when entering terrain with stiff surface snow.
The arrival of the arctic front on Wednesday resulted in a cycle of natural wind slab avalanches. These slabs were up to 45 cm deep. The freshly formed wind slabs were also reactive to human triggering, with whumpfs and shooting cracks reported by the Yukon Field Team.
Looking ahead, these wind slabs may remain reactive to rider triggering in wind-loaded terrain features, and new wind slabs may form due to southwest winds.
Most surfaces are likely wind-affected after the passage of the arctic front, but you may still find pockets of soft snow in sheltered areas.
A layer of surface hoar that formed on Christmas Eve may be found 50 cm deep, but recent observations suggest it has bonded. Snowpack depths range from 80 to 200 cm, with local variations due to wind redistribution.
