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

Seek out areas sheltered from the wind for the best riding and lowest avalanche hazard.

Confidence

Moderate

Avalanche Summary

We haven't received any recent reports of avalanches. If you're heading into the backcountry please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

Around 10 cm of recent snowfall is set to be blown into fresh wind slabs by forecast strong southwesterly winds. These new wind slabs may take a while to bond to underlying hard layers of previously formed dense wind affected snow. Soft snow, and the best riding, is likely to be found in sheltered terrain at treeline. The overall midpack is generally settled and strong, with the average snowpack depth at treeline around 150 cm.

Weather Summary

Thursday Night

Cloudy with 1 cm of new snow, southwest alpine wind 40 km/h, treeline temperature low -8°C.

Friday

Cloudy with 1-4 cm of new snow, south alpine wind 40 to 60 km/h, treeline temperature -4°C.

Saturday

Cloudy with 6-10 cm of new snow expected, southwest alpine wind 70 to 80 km/h, treeline temperature 0°C and freezing levels rising to 1100 m.

Sunday

Cloudy with 7- 15 cm of new snow expected, southeast alpine wind 50 to 60 km/h, treeline temperature 1°C and freezing levels rising to 1300 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • 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.
