Regions

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

Wind slabs can be found on all aspects from variable winds, be cautious moving into wind-affected terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in the region.

 We expect that new rider triggerable wind slabs  could be found on all aspects on Tuesday.

Snowpack Summary

aspects and at all elevations.

A layer of surface hoar that formed on Christmas Eve may be found 50 cm deep, but recent observations suggest it has bonded.

Weather Summary

Monday Night

Clearing throughout the night, up to 2 cm of new snow possible, northeast alpine wind 25 to 40 km/h, treeline temperature -15°C.

Tuesday

Mostly sunny with no new snow expected, northeast alpine wind 20 to 40 km/h, treeline temperature -11°C.

Wednesday

A mix of sun and cloud with up to 5 cm of new snow expected, northeast alpine wind 35 to 50 km/h, treeline temperature falling to -18°C.

Thursday

A mix of sun and cloud with up to 5 cm of new snow expected, northeast alpine wind 35 to 50 km/h, treeline temperature falling to -21°C.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Avoid slopes that sound hollow or drum-like.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.

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.
