Avalanche Forecast

Moderate

No new avalanche activity has been reported in the past few days.

Whumpfing has been experienced by backcountry users in the Babines, Grizzly Plateau, and Hudson Bay Mountain recently. The whumpfing is likely due to the surface hoar layers described in the snowpack summary.

Light amounts of recent new snow has been redistributed by primarily southerly winds. Southerly faces in the alpine are scoured down to the ground or an early-season crust. In most areas, two or more preserved surface hoar layers can be found buried between 35 cm and 80 cm deep. They appear to be most prominent at treeline and below but have been observed in some alpine locations as well.Snowpack depths at treeline are variable across the region with generally deeper amounts (~150cm) in the western part and shallower (~80cm) in the eastern part.The snow surface is likely moist or crusty up to treeline. Below 1100 m there is very little snow.

Sunday Night

Mostly cloudy with isolated flurries, southwest wind 10-25 km/h, high of -6 °C at treeline.

Monday

Mainly cloudy with sunny breaks and some isolated flurries, southeast and southwest wind 20-40 km/h, high of -5 °C at treeline.

Mostly cloudy with 1-4 cm of snow, southwest wind 30-50 km/h, high of -4 °C at treeline.

Mix of sun and cloud, west wind 20-30 km/h, high of -3 °C at treeline.

More details can be found in the Mountain Weather Forecast.

• Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
