Sea To Sky

Hard wind slabs exist at higher elevations, so the best and safest riding is likely in sheltered terrain.

Moderate - Timing, track, or intensity of incoming weather system is uncertain

WEDNESDAY: Mix of sun and cloud, light winds, alpine temperatures at -12.THURSDAY: Scattered flurries with accumulations of 5 cm, 30-50 km/h south winds, alpine temperatures at -12.FRIDAY: 15-25 cm, 20-30 km/h southwest winds, alpine temperatures at -8.

No new avalanches were reported on Monday or Tuesday and explosive cornice control did not trigger any avalanches on the slopes below. However, wind slabs may remain reactive to human-triggering in isolated wind loaded areas in the alpine and at treeline.

Surface conditions are highly variable throughout the region. Strong winds over the weekend formed hard and stubborn wind slabs on lee features, and scoured windward features. With winds shifting to the northeast, new soft wind slabs may be forming on south and west aspects. 10-20 cm of low density snow exists in sheltered areas and offers the best riding. Surface snow has begun to facet with the cold air temperatures, and will likely create a weak interface when the next storm arrives. The mid-pack is generally strong, with a widespread mid-November crust buried 70-100 cm at treeline and anywhere from 30-200 cm deep in alpine terrain. Snowpack and explosive tests have shown the crust to be unreactive, but it could remain a problem in shallow alpine start zones.
