Regions

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

Soft snow can be found in terrain sheltered from the wind.

Use caution in thin-to-thick snowpack areas in the alpine where persistent slabs may be easier to trigger.

Confidence

Moderate

  • We are confident due to a stable weather pattern.

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Roughly 10 to 15 cm of snow has incrementally accumulated and redistributed by moderate wind building small wind slabs over various old surfaces.

In the alpine, a buried surface hoar layer may remain intact on sheltered northerly terrain and hard wind-pressed surfaces, wind slab, and sastrugi exist on exposed slopes. A breakable melt-freeze crust can be found from 1200 to 1500 m on all aspects but north.

The lower snowpack is faceted and generally weak, particularly in shallow areas.

Weather Summary

Wednesday Night
Cloudy. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Thursday
Mostly cloudy. 1 to 2 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -4 °C.

Friday
Mix of sun and clouds. 2 to 3 cm of snow. 30 km/h northeast ridgetop wind. Treeline temperature -4 °C.

Saturday
Sunny. 30 km/h northeast ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Wind slabs are isolated, but may remain reactive.

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.

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.
