Regions: Jasper.

Approach this improving stability cautiously. Human triggered avalanches are still very possible.

Weather Forecast

Light variable winds shifting south through west, clear skies and cool overnight temps. No new snow in the near future

Snowpack Summary

A steady cooling trend has helped in tightening up the snow pack. Touchy wind slabs still exist in isolated areas at tree line and sub alpine elevations. The facet crust layers near the base of the snowpack are the most susceptible to human triggering from shallow areas and more likely in open areas at tree line and above.

Avalanche Summary

No new avalanches observed or reported in the bulletin region.

Avalanche Problems

Deep Persistent Slabs

Deep persistent slabs at tree line and sheltered sub-alpine slopes can be triggered from shallow areas within the snowpack.
Carefully evaluate and use caution around thin snowpack areas.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 3

Wind Slabs

Approach loaded, cross-loaded and re-loaded lee features with caution.
Be careful with wind loaded pockets while approaching and climbing ice routes.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
