Regions: Akamina, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West, South Rockies.

Rapid warming will increase the likelihood of triggering large avalanches.

The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.

Confidence

Moderate

Avalanche Summary

Numerous natural and rider triggered wet loose avalanches up to size 1.5 on sunny aspects were reported on Saturday.

Data is limited in this region. Please consider posting your observations to the Mountain Information Network.

Snowpack Summary

Strong solar radiation has formed a surface crust everywhere except north facing terrian at upper elevations.

20 to 30 cm of recent snow overlies a crust on all but north facing aspects in the alpine.

A persistent weak layer of facets are sitting on top of a second buried crust down 80 to 120 cm. This layer is unlikely to human trigger in areas where a thick crust below the recent snow is present. However, steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places where it may be possible to trigger this layer with large loads.

Terrain and Travel Advice

  • The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • If triggered loose wet avalanches may step down to deeper layers resulting in larger avalanches.
  • Cornice failure may trigger large avalanches.

Avalanche Problems

Persistent Slabs

Rapid warming increases the likelihood of triggering very large avalanches on deeply buried weak layers.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3

Wind Slabs

Recent wind has varied in direction so watch for wind slabs on all aspects.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Expect the high freezing levels and sunshine to trigger wet loose avalanches on all but true north aspects in the alpine.

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

Elevations: All elevations.

Likelihood: Very Likely

Expected Size: 1 - 1.5
