Regions

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

Continue to assess conditions and approach wind-exposed terrain with caution. Recently formed wind slabs may remain reactive to human triggering.

Confidence

Moderate

Avalanche Summary

No new avalanche activity has been reported.

If you are out in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

Strong southerly winds have redistributed surface snow into wind slabs up to 70 cm deep in lee slopes and terrain features. Below roughly 1700 m the upper snowpack has been saturated by recent rain and will likely freeze onto a widespread crust by Friday morning. In general, the mid-pack is well-settled with no significant weak layers of concern.

Snowpack depths are highly variable but generally average roughly 125 cm at treeline and 200 cm in the alpine. In areas where the snowpack is less than 1 meter in depth, it is reported to be faceted and unconsolidated.

Weather Summary

Thursday night

Mostly clear, with no precipitation. Moderate westerly alpine winds. Alpine temperatures -5 to -10 C.

Friday

Mix of sun and cloud, no precipitation. Light to moderate northerly alpine winds. Alpine temperatures -5 to -10 C.

Saturday

Mostly sunny, no precipitation. Moderate northerly alpine winds. Alpine temperatures -10 to -20 C.

Sunday

Mostly sunny, no precipitation. Light northwest alpine winds. Alpine temperatures 0 to -5 C with potential for a temperature inversion.

Terrain and Travel Advice

  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.

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.
