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

Generally good riding conditions exist. Use caution in steep, lee terrain features where wind slabs may be found.

Confidence

High

Avalanche Summary

The Field Team observed a size 2 wind slab avalanche on an east aspect in the alpine in Powder Valley that probably occurred on Wednesday, from steep, rocky terrain.

We haven't received any other recent reports of avalanches. Looking forward, it remains possible for riders to trigger wind slabs in steep, lee terrain features.

If you head into the backcountry please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

5 to 15 cm of recent snow overlies hard surfaces. This new snow may be redistributed into wind slabs in exposed areas from southwest winds.

The mid and lower snowpack is generally strong. A thick, well-bonded melt-freeze crust is approximately 30 to 50 cm above the ground at elevations below 1200 m.

Snowpack depths range from 80 to 200 cm across the region and vary locally from wind distribution.

Weather Summary

Friday Night

Partly cloudy, north alpine wind 10 km/h, treeline temperature -14 °C.

Saturday

Mostly clear skies with no precipitation, northwest alpine wind 10 km/h, treeline temperature -15 °C.

Sunday

Increasing clouds with a few centimetres of snow late in the day, south alpine wind 20 to 40 km/h, treeline temperature -15 °C.

Monday

Mostly cloudy with a trace of snow, south alpine wind 20 to 40 km/h, treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Carefully evaluate big/extreme terrain features before committing to them, it may not be full "go" time yet.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.

Avalanche Problems

Wind Slabs

Wind slabs may exist in lee terrain features at high elevations from recent southwest wind transport.

Aspects: North, North East, East, South East, West, North West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
