Regions

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

After many windy and cold days the best riding is likely in sheltered terrain that is less wind effected and where cold temps have softened the snow surface

Confidence

Low

Avalanche Summary

No new avalanches were observed in the past few days.

Thank you for all the great Mountain Information Network reports! Our forecasters really appreciate them. Please keep them coming!

Snowpack Summary

Early this week strong easterly winds scoured east slopes and created hard wind slab on south and west facing slopes.

A layer from mid November is buried 50 to 70cm at treeline. This layer consists of surface hoar, facets and a crust below treeline and on south facing slopes.

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

Weather Summary

Friday Night

Clear with no new snow expected. Light northwest winds developing overnight and a temperature inversion with -2 at valley bottoms and a high of -11 at 1600m.

Saturday

Clear skies with no new snow expected. Light northwest winds. Temperature inversion expected with a high of -6 at 1600m and -17 at valley bottom.

Sunday

Sunny with no new snow expected. Light winds from the northwest. Temperature inversion continues with a high of -1 at 1600m.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.

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.
