Regions: Little Yoho.

Good ski quality in sheltered areas in Little Yoho. Although conditions are improving, we are still leery to head into larger alpine features. It will take a bit of time yet to increase our confidence.

Weather Forecast

Light snowfall, gusty winds, and and gradually warming temperatures each day this week will hold the avalanche forecast steady.

Snowpack Summary

Wind effected surface snow and settling storm snow overlies three mid- pack weak layers 100-130cm down that are gaining strength. These layers continue to produce moderate, sudden planar test results on surface hoar in deep tap tests, and hard to no results with standard compression tests. Thin snowpack areas are degrading/facetting in the cold.

Avalanche Summary

No new avalanches reported or observed in the last 48 hours.

Confidence

Timing, track, or intensity of incoming weather system is uncertain

Avalanche Problems

Persistent Slabs

In the deeper snowpack areas west of the divide the previously reported persistent weak layers within the mid-pack (Dec 15, Jan 6, and Jan 16 layers) are becoming stronger and only producing hard to no results with pit tests.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 2 - 3.5
