Regions: Jasper.

Great riding in sheltered locations.

Flurries not enough to refresh your favourite line this weekend but, the cold temps have likely faceted the tracks!

Be cautious near overhead features, avalanches can run far on the Dec crust, TL and below.

Weather Forecast

Friday: Cloudy with sunny periods and isolated flurries. Trace. Temp: High -8 Â°C. Wind W:15-35 km/h.

Saturday: Cloudy with sunny periods and isolated flurries. Trace. Temp: Low -22 Â°C, High -14 Â°C. Wind west: 20 km/h gusting to 55 km/h.

Sunday: Mainly cloudy with isolated flurries. Trace. Temp: Low -13 Â°C, High -8 Â°C. Wind west: 20-30 km/h.

Snowpack Summary

Cold temperatures continue to promote faceting. Continued wind slabs building in deposition zones. The mid-pack is supportive with a questionable interface down close to 40cm, which has questionable reactivity below 1900m. Basal faceting continues near or on the ground.

Avalanche Summary

No new avalanches observed or reported today, poor afternoon visibility.Â

Avalanche Problems

Wind Slabs

Building wind slabs due to continued small snow inputs and steady moderate wind. Careful assessment is required with local terrain influences.

If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Variable winds may create pockets of wind slab in some unexpected locations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2.5

Persistent Slabs

This layer is a rain crust up to 1950m and reactive to large loads. Typically this layer is down around 40cm.

Dig down to find and test weak layers before committing to a line.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood: Possible

Expected Size: 1.5 - 3

Deep Persistent Slabs

Natural deep avalanches are getting less frequent yet it remains a low probability and high consequence event if you push your luck.

Pay attention to overhead hazards like cornices which could trigger the deep persistent slab.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1.5 - 3
