Regions

Northwest Inland, Nass, Seven Sisters, Howson, Kispiox, Microwave-Sinclair, Ningunsaw, Ningunsaw, Ningunsaw, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

Watch out for early-season hazards like rocks and stumps.

Small wind slabs may linger at high elevations.

Confidence

Low

Avalanche Summary

No new avalanches have been reported since before last weekend.

Looking forward, lingering pockets of wind slab at upper elevations will be the main concern.

Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

Up to 25 cm of snow overlies a crust from rain last week. At upper elevations, this has likely been redistributed by the wind.

The remainder of the snowpack is strong, with various hard layers and crusts.

Weather Summary

Wednesday Night

Partly cloudy. 20 km/h south ridgetop wind. Treeline temperature -5 °C.

Thursday

A mix of sun and cloud with 1 cm of snow. 15 to 30 km/h south ridgetop wind. Treeline temperature -6 °C.

Friday

A mix of sun and clouds, increasing in the afternoon. 10 to 20 km/h south ridgetop wind. Treeline temperature -6 °C.

Saturday

Cloudy with 10 to 15 cm of snow. 15 to 30 km/h southeast ridgetop wind. Treeline temperature -7 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Be careful as you transition into wind-affected terrain.
  • Make observations and continually assess conditions as you travel.

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.
