Avalanche Forecast

A few size 1 loose dry avalanches have been reported in extreme terrain. Otherwise, there have been no new avalanches reported.

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.

Check out this great MIN from the north of the region.

Up to 25 cm of soft snow exists in sheltered areas. Wind-exposed areas carry a variety of surfaces including wind-stiffened snow, an early-season crust, or completely scoured with the ground visible.

Below treeline, a crust exists at or near the surface.

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.

Wednesday Night

Cloudy with 0 to 5 cm of new snow, south alpine winds 25 to 45 km/h, treeline temperature -5°C.

Thursday

Partly cloudy with a trace of new snow possible, southwest alpine winds 35 to 50 km/h, treeline temperature -4°C.

Friday

Cloudy with up to 5 cm of new snow expected, southwest alpine winds 30 to 50 km/h, treeline temperature -4°C.

Saturday

Partly cloudy with a trace of new snow possible, northwest alpine winds 10 to 20 km/h, treeline temperature -8°C.

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.
