Regions

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

The wind continues but at least it will be bringing with it some new snow.

The best riding will still be in the trees and in sheltered areas away from the wind.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported, but observations are limited this time of year. If you do head into the backcountry please submit a MIN report! Thanks to everyone who has!

Snowpack Summary

Strong easterly winds have scoured east slopes and created hard wind slabs on the south and west-facing slopes.

A layer from mid-November is buried 50 to 70 cm down at the treeline. This layer consists of surface hoar and facets. Below the treeline and on south-facing slopes it is a crust. November 27th and 28th saw activity on this layer but has so far seemingly been unreactive under the current conditions.

Many early-season hazards exist below treeline such as rocks, stumps, and open creeks.

Weather Summary

Friday

A mix of sun and cloud, trace accumulation, winds south 15 to 20 km/h, -10 C at 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Use caution when approaching steep and rocky terrian.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.

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.
