Regions: Jasper.

Southern aspects getting a mix of strong winds and solar punch making conditions challenging.

Looks for sheltered north aspects for good, dry snow.

Weather Forecast

A re-shuffling of weather systems to remain offshore and so, for the near future should leave us with fairly benign weather conditions to the region over the next couple of days. Alpine wind speeds expected to abate to light values for Tuesday and Wednesday. 

See Weather synopsis here: Avalanche Canada Mountain Weather Forecast

Snowpack Summary

SW winds have created deep pockets of windslab and pronounced cornice development on North aspects. Mixed slab character, support and sensitivity in the mid-pack is bridging the deeper basal facets and depth hoar. Average HS at treeline: ~160cm.

Avalanche Summary

Previous large avalanches observed on Northerly aspects and triggered by large loads (like cornices).

Confidence

Avalanche Problems

Wind Slabs

Wind slabs are prevalent through the forecast region. Their sensitivity will vary particularly with local loading and wind patterns.

  • Assess start zones carefully and use safe travel techniques.
  • If triggered the storm/wind slabs may step down to deeper layers resulting in large avalanches.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3

Deep Persistent Slabs

Shallow snowpack zones and/or large triggers such as cornice failures could trigger this deep layer. The consequences would be severe!

  • If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
  • Assess start zones carefully and use safe travel techniques.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Unlikely

Expected Size: 1.5 - 3
