Regions

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

Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Confidence

High

Avalanche Summary

No new avalanches have been reported in this region recently.

If you do go into the backcountry, consider submitting a MIN report.

Snowpack Summary

Riders report highly variable travel conditions from soft to wind-affected to crusty.

10 to 20 cm of snow accumulated on the weekend, which was redistributed in wind-exposed terrain, forming firm surfaces. Soft snow may be found in sheltered areas. A hard melt-freeze crust is found 10 to 40 cm deep, up to 1500 m around White Pass, and 1200 m in the Wheaton Valley.

Weather Summary

Thursday Night

Increasing cloud. 20 to 35 km/h south ridgetop wind. Treeline temperature -15 °C.

Friday

Cloudy with up to 5 cm of snow. 50 to 80 km/h south ridgetop wind. Treeline temperature -12 °C.

Saturday

Cloudy with 5 to 15 cm of snow. 60 to 80 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Sunday

Cloudy with up to 5 cm of snow. 50 to 70 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
