Regions: Little Yoho.

Monitor local snow depths as thin areas may have developed facets at the base of the snowpack.

Weather Forecast

Cooling temperatures for Monday with lows at 3000m in the -17C to -12C range, light to moderate NW winds and no snow for the next 48 hours.

Snowpack Summary

10-20cm of snow over the last week over isolated suncrusts and surface hoar. Widespread wind effect from previous extreme winds. Of greatest concern are the weak facets and depth hoar at the base of the snowpack which only exist in thin areas of Little Yoho ( under 150cm). Otherwise the facets are of little concern.

Avalanche Summary

No new avalanches observed or reported today.

Avalanche Problems

Deep Persistent Slabs

In Little Yoho, areas with a thin snowpack with more developed faceting still raise concern. Many of the areas in this region hold a deeper snowpack where this problem is not a concern. Travelers are advised to investigate snow depths with a probe.

Avoid thin, rocky or unsupported slopes.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
