Regions

Yukon, Tutshi, Wheaton, White Pass East, White Pass West.

Continuously assess conditions as you move through terrain.

Avoid thin-to-thick areas like rocky outcrops where you're more likely to trigger avalanches on weak layers.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in the region on Wednesday.

No new persistent slab avalanches have been reported in the past week, but uncertainty remains regarding the early December layer mentioned in the snowpack summary.

If you're heading into the backcountry please consider making a MIN report with your observations and photos from the day. All information is helpful for forecasters!

Snowpack Summary

Previous strong outflow wind has created variable snow surfaces in exposed terrain on all aspects and elevations. Ongoing cold temperatures have softened the upper snowpack in sheltered terrain.

A weak layer of facets and a crust from early December is buried 60 to 100 cm deep. This layer exists on all aspects up to 1750 m. This layer remains a concern in this region.

At the highway elevation the snow is 120 cm deep and in the alpine exceeds 200 cm.

Check out this MIN report from the Yukon field team for recent snowpack observations.

Weather Summary

Thursday Night

Partly cloudy with isolated flurries, trace amounts of snow. 20 to 30 km/h southeast ridgetop wind. Treeline temperature -19 °C.

Friday

Partly cloudy. 30 to 40 km/h south ridgetop wind. Treeline temperature -18 °C.

Saturday

A mix of sun and cloud. 30 to 50 km/h south ridgetop wind. Treeline temperature -16 °C.

Sunday

Partly cloudy with isolated flurries, 1 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -12 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be mindful that deep instabilities are still present in the snowpack.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.
  • Cornice failures could trigger large and destructive avalanches.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
