Wind slabs may remain a risk at higher elevations following recent snowfall and strong winds.

Confidence

Moderate

Avalanche Summary

A size 1 wind slab avalanche was remotely triggered by a skier on Tuesday in the Seaton area. The skier was skiing a low-angle slope, while an adjacent wind-loaded, steep roll released. This occurred in north-facing, alpine terrain.

Snowpack Summary

Approximately 10 to 15 cm of new snow has buried a widespread crust. Strong winds have scoured surfaces down to the crust in most windward-facing terrain while forming deeper deposits of snow in lee terrain.

Currently, no significant concerns exist deeper in the snowpack.

Weather Summary

Wednesday Night

Mostly clear skies. 10 to 30 km/h northwest ridgetop wind. Treeline temperature -6 °C. Freezing level at valley bottoms.

Thursday

Cloud building through the day. 0 to 20 km/h north ridgetop wind. Treeline temperature -4 °C. Freezing level 1200 m.

Friday

Mix of sun and cloud. 0 to 20 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1400 m.

Saturday

Mostly cloudy with 0 to 2 cm of snow. Freezing level 1400 m. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Start with conservative lines and watch for clues of instability.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
