Yukon

Evaluate your line for wind slabs and cornice exposure before committing to consequential terrain.

Thursday night: A trace of snow. Up to 10 cm at Haines Pass. Light to moderate southeast wind. Alpine low around -8 °C.

Friday: Cloudy with flurries bringing a trace. Up to 5 cm at Haines Pass. Light to moderate southeast wind. Alpine high around -6 °C.

Saturday: Mostly sunny. Light southwest wind. Alpine high around -9 °C.

Sunday: Mostly sunny. Light west wind. Alpine high around -11 °C.

Avalanche activity has been minimal. A size 1.5 wind slab out of a steep couloir feature was the only report in the White Pass area on Thursday.

If you head out into the mountains, and you have photos to share, conditions to report on, or just some stoke about the good riding, consider making a post on the Mountain Information Network. 

Around 50 cm of new and recent snow is settling and bonding well. Wind slabs can be found near ridge tops, below convexities and in steep or extreme terrain in the alpine.

A couple of sun crusts exist in the upper snowpack but none have been identified as layers of particular concern. The lower snowpack is thought to be well protected by the dense, wind-pressed layers above, and it is unlikely that avalanches will be triggered on weak, sugary crystals near the ground at this time.

• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
• Avoid exposure to slopes that have cornices overhead.
• Even small cornices may have enough mass to be destructive and deadly.
