Weather Forecast

Broken skies forecasted for Saturday. Progressive warming over the day and continuing thought the weekend. High's expected to be near -10 in the Icefields area.

Snowpack Summary

A layered, complex, shallow, faceted and weak snowpack. Multiple surface and buried wind slabs overlying a variety of faceted weaknesses to ground. Forecasters backed off a small alpine feature today due to a noticeable change in surface tension and hard hollow sounding wind slab. 

Avalanche Summary

A few loose slides observed from steep terrain today. Size 2 shallow wind-slab from the alpine (2600m, SW aspect) on a loaded rib feature on Boundary Peak

Confidence

Intensity of incoming weather systems is uncertain on Monday

Avalanche Problems

Wind Slabs

Variable winds have created a complex situation of cross and, reverse loaded features through the region. Stripped ribs, ridge-tops, and open features threaten to push users into areas where the snow is over-loaded and created layered wind-slabs.
Be careful with wind loaded pockets. Be aware of wide variation in snowpack depthCaution in lee and cross-loaded terrain near ridge crests.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

The faceted snowpack continues to lose cohesion and release loose dry avalanches from steep terrain. This is concerning for ice-climbers and skiers in confined/exposed terrain.
Use caution above cliffs where small avalanches may have severe consequences.Be very cautious with gully features.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
