Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Powell River, Spearhead, Tantalus, Sky Pilot.

Expect avalanche danger to increase through the day as new snow accumulates.

Use conservative route selection and resist venturing into complex terrain.

Confidence

Moderate

  • Forecast snowfall amounts are uncertain.
  • The snowpack structure is generally well understood.

Avalanche Summary

No new avalanches were reported.

If you are heading into the backcountry, please consider sharing your observations via the Mountain Information Network.

Snowpack Summary

Up to 15 cm of new snow has fallen at treeline on Saturday morning. This new snow will overlie a variety of surfaces, including a crust on south-facing aspects, wind-affected snow on north-facing terrain above 2100 m, and surface hoar on isolated, sheltered features.

The mid-December crust is 100 to 200 cm deep and well-bonded to the snow above. Above 2200 m, this crust is absent and a layer of facets and a crust from November is found at the base of the snowpack. These layers are not currently a concern.

Weather Summary

Saturday Night

Cloudy. 10 to 20 cm of snow. 50 km/h southeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Sunday

Cloudy. 15 to 25 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Monday

Partly cloudy. 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Tuesday

Cloudy. 15 to 25 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1100 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Watch for rapidly changing conditions during periods of heavy loading from new snow, wind, or rain.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.

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.
