Regions

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

Wind slabs may remain reactive to riders at upper elevations. Expect deteriorating visibility in the afternoon as the next storm blows in.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

In the good visibility on Friday, evidence of a natural wind slab cycle up to size 2.5 was observed in the alpine from the mid-week wind event.

This MIN from Friday describes whumphing and remote-triggering a wind slab from 30 m away on a convex slope at treeline.

Explosive work on Thursday and Friday produced numerous size 2 cornice results.

Snowpack Summary

New snow dusts extensively wind-affected surfaces at upper elevations and possibly sun crust on steep solar aspects.

Below 2100 m, a widespread crust is buried 20 to 60 cm deep. The snowpack below the crust is generally well settled and has no significant layers of concern.

Weather Summary

Saturday Night
Partly cloudy. 30 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Sunday
Mostly cloudy. 2 to 4 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Monday
Cloudy. 20 to 40 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Tuesday
Cloudy. 30 to 75 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 1 °C.

Terrain and Travel Advice

  • Be alert to changing conditions throughout the day.
  • Be careful as you transition into wind-affected terrain.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
