Regions: Jasper.

There is still a high degree of spatial variability and low confidence in the stability of the snowpack. In many areas there is a significant load sitting on a weak mid-pack.

Weather Forecast

No new precipitation on the horizon. Mild temperatures with calm to light Southwesterly winds. Sunny and clear.

Snowpack Summary

Last week's 20-30cm of rapidly settling and wind distributed storm snow overlies facets and basal weakness. New reactive windslabs in lee gully features and especially on NE aspects. Extensive scouring of last weeks snowfall at and above treeline.

Avalanche Summary

No patrol today.

Confidence

Avalanche Problems

Wind Slabs

Main concern is for cross loaded gully features and steep rocky convexities on lee aspects where fresh windslabs are present.
Be careful with wind loaded pockets while approaching and climbing ice routes.Use caution in lee areas. Recent wind loading has created wind slabs.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3

Deep Persistent Slabs

The weak lower snowpack is susceptible to triggering in lee areas that have been recently loaded by SW winds and last week's snow.
If triggered the wind slabs may step down to deeper layers resulting in large avalanches.Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
