Regions

South Coast, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron, Coquihalla, Harrison-Fraser, Manning, Skagit.

Check for wind slabs before committing to steep slopes.
The snowpack is shallow and hides early season hazards.

Confidence

Moderate

Avalanche Summary

No avalanches have been reported. However, observations are limited.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

Above treeline, there is 10 to 20 cm of dry snow sitting on several supportive crusts which extend to the ground. There is around 60 to 80 cm total of snow at treeline which shrinks rapidly below treeline.

In wind exposed areas, soft snow has likely been redistributed into lee features.

Weather Summary

Saturday Night
Clear skies. 10 km/h northeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Sunday
Sunny. 10 km/h northwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Monday
Mix of sun and clouds. 3 to 4 mm of precipitation as snow or rain at treeline. 20 km/h west ridgetop wind. Treeline temperature -2 °C. Possible above freezing layer.

Tuesday
Mix of sun and clouds. 1 to 2 cm of snow. 25 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1200 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Watch for areas of hard wind slab on alpine features.
  • Be cautious of buried obstacles, especially below treeline.

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.
