Regions

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

Reactive slabs may persist after recent stormy weather. Give the recent snow time to stabilize before committing to bigger slopes.

Confidence

Moderate

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

Avalanche Summary

Several small (size 1) storm slabs and loose dry avalnches where reported on Wednesday, all occurring in steep terrain features.

If you head out, please consider posting your observations to the Mountain Information Network.

Snowpack Summary

Strong to extreme southwesterly winds redistributed 10 to 30 cm of new snow in exposed terrain at higher elevations on Wednesday.

Approximately 40 to 80 cm of snow now overlies a widespread crust below 2100 m. This crust becomes thin or absent at higher elevations.

The snowpack below the crust is generally well settled and has no significant concerns currently.

Weather Summary

Thursday Night
Cloudy. 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -8 °C.

Friday
Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Saturday
Mostly sunny. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Sunday
Mostly cloudy. 1 to 3 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

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.
  • Avoid freshly wind-loaded terrain features.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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.
