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

Continually assess the extend of wind effect as you gain elevation. Rider triggerable wind slab could be found on exposed terrain features.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported in the region.

If you do go into the backcountry, consider submitting a Mountain Information Network report.

Snowpack Summary

Ongoing snowfall accompanied by southerly winds could add to the wind slab problem.

A crusts can be found down around 50 cm on terrain below 1200 m, except on wind scoured slopes where it could be on the surface.

The snowpack is now above threshold for avalanches on smooth slopes at treeline. The snowpack in general is shallower than usual for this time of year and early season hazards are still a concern.

Check out this MIN from our field team that summarizes conditions at Fraser Chutes.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs are most reactive during their formation.
  • Use ridges or ribs to avoid areas of wind loaded snow.

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.
