Regions: Little Yoho.

Danger levels have moved to LOW at all elevations owing to melt-freeze crusts to treeline, and wind blasted snow above. Ski conditions are generally rugged, while ice climbing conditions in Field are excellent - plastic ice and low avalanche danger.

Weather Forecast

A westerly flow continues, with no significant systems moving through the area for the next 24-hours. Expect Friday to be sunny with some clouds, particularly late in the day. Temperatures will range from 0 to -8, and  expect 3-5 cm of snow overnight on Friday. This might just freshen up the ski quality for Saturday.

Snowpack Summary

After a period of warm weather, the return to colder temperatures has improved the stability of the snowpack, particularly at treeline and below where strong melt-freeze crusts now dominate. In isolated areas we expect the Dec 18 surface hoar layer to remain, but triggering is unlikely. Recent winds have blasted the terrain at higher elevations.

Avalanche Summary

No new avalanches observed or reported today.

Confidence

Due to the number and quality of field observations

Avalanche Problems

Persistent Slabs

While ski conditions are very challenging right now, avalanche conditions have improved. Although it seems unlikely, we are still wondering about the presence of the Dec 18 surface hoar layer down about 50 cm from the surface.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
