Windslabs can be found on all aspects from variable winds, be cautious when you transition into wind affected snow.

Cold exposure remains a major concern. (Read more in this blog).




Avalanche Summary

The arrival of the arctic front on Wednesday resulted in a cycle of natural wind slab avalanches. The freshly formed wind slabs were also reactive to skiers, with whumpfs and shooting cracks reported by the Yukon Field Team.

Snowpack Summary

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.
