Regions: Babine, Hudson Bay, Microwave-Sinclair, North Bulkley, South Bulkley, Telkwa.

A conservative approach to terrain is critical, watch for newly-formed and reactive wind slabs as you transition into wind-affected terrain.

Moderate

Avalanche Summary

A few slab avalanches (up to size 2) were observed on Tuesday. They were a couple of days old days old and occurred during the last storm.

If you go into the backcountry, please consider submitting to the Mountain Information Network.

Snowpack Summary

5 to 15 cm of new snow may accumulate by Wednesday afternoon. Strong southerly wind will likely form deeper deposits on northerly aspects.

Up to 40 cm of snow sits above a variety of old snow surfaces including soft, faceted snow in sheltered terrain and wind-affected snow in exposed terrain.

A layer of faceted snow on a crust and possibly surface hoar (in sheltered locations) is now buried 50 to 60 cm down.

A facet/crust layer from early December is buried approximately 70 to 110 cm deep. This layer is generally not a concern in this region at this time.

Weather Summary

Tuesday Night

Cloudy with snow 3 to 5 cm. 25 gusting to 65 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 700 m.

Wednesday

Cloudy with snow 5 to 10 cm. Less snow as you move further to the east. 40 gusting to 85 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1600 m.

Thursday

Mix of sun and cloud. Isolated flurries. Snow 10 to 15 cm. 25 to 70 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Friday

Cloudy with sunny periods. 15 to 25 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • Conservative terrain selection is critical; choose gentle, low consequence lines.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.

Avalanche Problems

Wind Slabs

Fresh and reactive wind slabs are likely on Wednesday. Wind slabs will be the most sensitive where they overlie facets.

Aspects: North, North East, East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
