Regions: Little Yoho.

Conditions have been improving over the past week. Thin areas and new snow instabilities are the main concerns, but there is great skiing to be had.

Weather Forecast

A general warming trend over the next 2 days with alpine temperatures in the -10C range warming to -5C by Saturday. Only a few cm of snow is expected in the next few days with W winds increasing by the weekend.

Snowpack Summary

15-30cm of generally low density snow sits over previous surfaces. In deeper snowpack areas in Little Yoho the main concern is for new snow instabilities. Profiles are showing no results in the deeper layers previously found active (Dec 10). In thin areas, basal facets are well formed and still a concern for triggering larger avalanches.

Avalanche Summary

No new avalanches observed or reported.

Confidence

Avalanche Problems

Wind Slabs

Some thin wind slabs have been triggered in isolated areas over the last few days which will only be a problem in the short term.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5

Deep Persistent Slabs

In Little Yoho, areas with a thin snowpack are still a question for forecasters. It is suspected that the deeper facet layers will be more prevalent in these areas . Check locally for snowpack depths as thicker regions do not have the same problem.

Be aware of the potential for wide propagations which could result in large avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3
