Points saillants

Assess for wind slab before committing to your line.

Great riding can be found in non-wind loaded terrain at treeline and above.

    Ongoing light snowfall and moderate winds will keep the wind slab problem active.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

In the past 3 days several natural cornice falls have been reported. Even without triggering slabs on the slopes below these cornices have resulted in size 2.5 debris.

Small dry and wet loose avalanches continue to be observed in steep terrain throughout the region.

Snowpack Summary

Light snow continues to accumulate with moderate southwest to west wind, forming deeper deposits on north and east aspects. A crust exists on or near the surface on previously sun exposed slopes and all aspects below 1600 m.

Good skiing and sledding is easily found at treeline and on non-wind loaded alpine terrain.

A thick crust is buried 30 to 70 cm deep, but may remain exposed in wind-scoured alpine terrain. It extends up to at least 1500 m in the Rockies, 2000 m in the Cariboos, and 2300 m in the North Monashees.

Below the crust, the snowpack is strong and well bonded.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
