Regions

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

While wind and snow should ease through Thursday, dangerous avalanche conditions may persist. Avoid avalanche terrain during heavy snow or strong wind.

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

Several rider-triggered storm slab avalanches, up to size 1, were reported on Tuesday, generally failing within the top 20 cm of the snowpack.

With additional snow and wind in the forecast, these storm slabs will likely grow in size and become more reactive.

Snowpack Summary

Unsettled weather continues to deliver variable snowfall across the region. Up to 50 cm of new snow may now bury a widespread crust up to 2000 m, formed during last weekend’s rain event. This crust is thin or absent at higher elevations. Strong southerly winds have redistributed the new snow in exposed terrain, while snow remains generally low-density in sheltered areas.

The mid and lower snowpack are generally well settled with no significant concerns at this time.

Weather Summary

Wednesday Night
Cloudy. 20 to 30 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday
Cloudy. 5 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Friday
Mostly cloudy. 5 to 10 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Saturday
Mostly sunny. 1 to 3 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • 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.
