Regions

Northwest Inland, Kispiox, Microwave-Sinclair, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

New snowfalls and wind will continue to build small and reactive wind slabs near ridgelines and rollovers. Choose sheltered slopes where the recent snow has not been wind-affected.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported, but observations are very limited at this time of year.

If you do go into the backcountry, consider submitting a Mountain Information Network report.

Snowpack Summary

Up to 15 cm of new snow has fallen over the weekend, likely redistributed by strong southerly winds at higher elevations.

The snowpack remains generally shallow, with early-season hazards just below the snow surface. A weak layer of faceted snow may be present at the base of the snowpack.

The height of snow at treeline is approximately 30 to 50 cm.

Weather Summary

A large weather system will move onto the north coast, bringing continued light precipitation and windy conditions to the region. Freezing levels are expected to rise to 1000-1500 m.

Sunday night

Light snow/rain; 5 cm. Moderate southwest ridgetop winds gusting 60 km/h. Treeline temperatures near -4 °C. Freezing levels around 1200 m.

Monday

Light snow/rain; 10-15 cm. Strong southwest ridgetop winds gusting 80 km/h. Treeline temperatures reach -1 °C. Freezing levels rise to 1400 m over the day.

Tuesday

Cloudy, snowfall tapers off. Steady southwesterly winds gusting 80 km/h. Treeline temperatures reach +2 °C. Freezing levels rise to 1500 m.

Wednesday

Cloudy with sunny periods. Moderate southwesterly winds gusting 60 km/h. Treeline temperatures reach -5 °C. Freezing levels at 1000 m.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Expect shallow snow cover that barely covers ground roughness.

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.
