Regions: Little Yoho.

Watch out for thinner areas at treeline and above that will have a weaker base. Assess the snow on each slope carefully for another few days.

Weather Forecast

Cooler temperatures and light snow is forecast for the next few days.

Snowpack Summary

Suncrust exists on steep S and W aspects. Otherwise, 20-30 cm of low density snow overlies a well settled mid-pack. The Feb 11 surface hoar can be found down 50-60 cm in isolated locations around treeline and produces moderate test results. The Jan 6th layer (down 80-120 cm) is gaining strength and producing hard to no results.

Avalanche Summary

No new avalanches noted.

Confidence

Due to the quality of field observations

Avalanche Problems

Persistent Slabs

We are tracking 2 weak layers in the upper 120 cm of the snowpack (Jan 6 and Feb 11 surface hoar). Their strength has improved, and they are sometimes hard to find. We consider these to be healing, but dig down and look for yourself.

Avoid convexities or areas with a thin or variable snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3
