Regions

Sea To Sky, South Coast, Brandywine, Garibaldi, Homathko, Powell River, Spearhead, Tantalus, North Shore, Sasquatch, Sky Pilot, Tetrahedron.

Winter returned to the mountains.

Triggering fresh storm slabs is possible on steep open slopes.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

Tuesday’s storm follows a period of limited avalanche activity, with reports of size 1 to 1.5 cornices failures and wet loose avalanches.

Looking ahead, concerns shift to the new snow: initially storm slabs in steep terrain, then lingering wind slabs, and eventually wet loose avalanches with sun and warming.

Snowpack Summary

Snowfall amounts will vary with location and elevation, so verify in the field and use more conservative terrain where snowfall is deeper. About 20 cm is expected east of Whistler, 30 cm west of Whistler and near Squamish, and up to 40 cm in higher terrain on the North Shore.

This snow falls on a mix of crusts and moist or isothermal snow, depending on aspect and elevation.

The snowpack has undergone multiple melt-freeze cycles, forming a series of crusts with dense, rounded snow between.

Weather Summary

Tuesday Night

Partly cloudy. Another 5 to 10 cm of snow ending around midnight. 30 km/h west ridgetop wind. Treeline temperature -7 °C.

Wednesday

Mix of sun and clouds. 0 to 2 cm of snow. 10 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Thursday

Mostly sunny. 20 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Friday

Mix of sun and clouds. 0 to 1 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use careful route-finding and stick to moderate angled slopes with low consequences.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
