Regions

South Coast, Powell River, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron, Harrison-Fraser.

Don't let the break in the storm lure you into consequential terrain.

Triggerable wind slabs exist.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported, but observations have been very limited in this region.

We expect that large, natural, and human-triggered avalanches will remain triggerable.

If you go into the backcountry, please consider submitting a Mountain Information Network (MIN) post.

Snowpack Summary

Between 50 and 90 mm has fallen as snow in high elevation areas, or as rain below treeline, in the past 24 hours.

At upper elevations, strong to extreme winds have formed deeper storm slabs on northeast through northwest-facing slopes.

Expect a rain-saturated snowpack or lack of snow at lower elevations.

Weather Summary

Thursday Night

Cloudy with 3 cm of snow. 20 to 30 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

FridayMostly cloudy with trace precipitation. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level rising to 1200 m.

SaturdayCloudy with 25 to 70 mm of precipitation, falling as snow above 750 m. 40 to 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1200 m.

Sunday

5 to 15 mm in the overnight period. Cloudy with trace precipitation. 20 to 40 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Choose low-angled, 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.
