Remain consistent and active in your snowpack and terrain assessment. Gather quality information before moving into steeper more committing terrain. Days are short, plan accordingly.

Weather Forecast

An upper ridge is deflecting any organized weather system from reaching our region. This is allowing a cool arctic air mass from the North to slip Southward, spreading cold and dry conditions over BC. Cloud with sunny periods for the day with an alpine high of -12 with light winds. Cold temps and clearing skies for the week.

Snowpack Summary

Surface hoar is growing in sheltered areas while a thin sun crust exists on steep solar aspects. 40cm of snow covers a earlier winter surface hoar or sun crust layer and can be found at all elevations. Winds have created a soft slab on this layer in specific lee or cross-loaded features. The October crust near the ground may be poorly bonded.

Avalanche Summary

A report of a size 2.0 skier accidental from the lookers right of Youngs Peak occurred two days ago, originating in steep rocky terrain. The crown was estimated at 40-50cm deep and about 50m wide terminating in lower angle terrain. No new avalanche observations from backcountry users in the last 48 hrs.

Confidence

The weather pattern is stable

Avalanche Problems

Persistent Slabs

This layer can be found at tree line and in the alpine but spotty in its distribution. It will be most reactive in areas where wind loading has occurred and encouraged slab development.

Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.Avoid thin, rocky or unsupported slopes.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
