Regions

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

Fresh snow brings new potential for small but reactive wind slab development. Watch for active wind transport.

Confidence

Moderate

  • We are uncertain whether the wind will be enough to form new wind slabs.

Avalanche Summary

No recent avalanche activity has been reported.

Reports in this region are limited, please post any photos or observations to the MIN if you head out!

Snowpack Summary

Outflow winds have sculpted the snowpack. Wind scoured, or hard snow surfaces exist in exposed terrain, while wind slabs are present in lee or cross loaded features.

The January 26 crust is buried 50–100 cm deep below 1350 m. Surface hoar may linger above this layer on sheltered north to east aspects. Human triggering is considered unlikely.

Facets or depth hoar exists at the base of the snowpack and may be a concern in areas with a shallow snowpack, such as inland terrain.

Weather Summary

Monday Night
Mostly cloudy. 40 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Tuesday
Mostly cloudy. 3 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Wednesday
Mostly cloudy. 10 to 20 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Thursday
Mix of sun and clouds. 3 cm of snow. 20 km/h southeast ridgetop wind. Treeline temperature -18 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.

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.
