Regions

Microwave-Sinclair, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

The softest snow and lowest avalanche danger can be found in terrain sheltered from the wind.

Confidence

High

Avalanche Summary

No new avalanches have been reported.

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

Snowpack Summary

A few lightly stormy days have given the surface a bit of a soft refresh. Moderate southerly wind has likely formed deeper deposits on northerly aspects.

This recent snow overlies a variety of surfaces including soft, faceted snow in sheltered terrain and wind-affected snow in exposed terrain.

A thick layer of faceted snow sits over a crust and possibly surface hoar buried in late January. This layer has the potential to be very close to the surface, or over 50 cm deep.

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

Sunday night

Mostly cloudy with a trace of snow. 20 to 405 km/h southwest ridgetop wind. Treeline temperature around -2 °C. Freezing level valley bottom.

Monday

Mostly cloudy with trace precipitation. 20 to 40 km/h southwest ridgetop wind. Freezing level 1300 m.

Tuesday

Mostly cloudy with trace precipitation. 20 to 40 km/h southwest ridgetop wind. Freezing level at valley bottom overnight, rising to 1300 m through the day.

Wednesday

Mostly cloudy 3 to 8 cm of snow. 40 to 60 km/h south ridgetop wind. Freezing level rising to 1700 m.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.

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.
