Thin wind slab avalanches might be triggered behind exposed features such as ridgelines, especially where wind deposits grade from thin to thick.

Highlights
Welcome to Avalanche Canada's Yukon avalanche forecast.
Current avalanche conditions are favourable. Watch for thin areas of wind slab in exposed areas near ridgetop.
Avalanche problems
Confidence
Moderate - Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary
Small wind slab releases were observed at the end of last week. No avalanches have been observed since then.
Snowpack Summary
Around 25 cm of soft snow overlies a relatively well-consolidated mid and lower snowpack with no obvious weak layers. In some locations you may find a 2 cm thick crust below the recent fresh snow. In exposed locations, the fresh snow has been blown into variable-thickness wind slabs, which may pose local hazards, but are not expected to propagate widely in most locations. Snow depths at White Pass average around 150 cm; deeper locations (higher terrain west of the highway) have as much as 200 cm. It's reasonable to expect a thin snowpack with sugary facets in the Wheaton Valley, although we'd don't yet have any observations to confirm this.
Terrain and Travel
- Watch for areas of hard wind slab on alpine features.
