Regions

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

Riders could trigger wind slabs in wind-exposed terrain. Seek areas sheltered from the wind for the best riding.

Confidence

Moderate

Avalanche Summary

We haven't received any recent reports of avalanches.

Snowpack Summary

New snow has been accompanied by northerly winds at valley bottom and southerly winds in the alpine. Hard wind slab may be found on all aspects and they may sit on a layer of weak facetted grains. Soft snow can still be found in sheltered terrain below treeline.

Check out this great MIN.

The midpack is settled and strong.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Approach lee and cross-loaded slopes with caution.
  • 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.
