Regions

South Coast, Powell River, Tantalus, North Shore, Sky Pilot, Tetrahedron.

Recent storm snow may still need time to stabilize and bond to underlying surfaces. Don't be lured by clearing skies into big terrain too quickly.

Confidence

Moderate

Snowpack Summary

Roughly 30 cm of recent snowfall has buried a widespread, thick crust at higher elevations. Strom snow may not bond right away to the underlying crust.

Conditions remain rugged at lower elevations with a shallow snowpack and a mix of wet snow and crusts.

Weather Summary

Sunday Night

Cloudy with 20 to 30 cm of snow, rain below 1000 m. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Monday

Clearing throughout the day with 0 to 2 cm of snow, rain below 1000 m. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -1 °C.

Tuesday

Sunny. 10 to 20 km/h north ridgetop wind. Treeline temperature -1 °C. Treeline temperature -1 °C.

Wednesday

Sunny. 40 to 60 km/h east ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • The new snow may require another day to settle and stabilize.
  • Expect shallow snow cover that barely covers ground roughness.

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.
