Regions

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

Wind slabs and wind-affected snow are found at higher elevations. The best riding will be in terrain sheltered from the wind.

Confidence

Moderate

Avalanche Summary

We haven't received any reports of recent avalanches. Looking forward, riders could trigger newly formed wind slabs in wind-loaded terrain.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

The alpine has received 50 cm of snow over the past week, which settled quickly. Strong southwest wind is redistributing the snow, loading cross-loaded and lee terrain features in the alpine. Wind-hardened surfaces are expected on southerly slopes. Wind-sheltered terrain may still have soft surfaces.

Cornices are large and looming at this time of year.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
