Little Yoho.

We have limited information about the Jan.17 surface hoar layer in this region. Although we have seen little activity, dig down to see if it is present, especially below 2000m.

Summary

Weather Forecast

Still cold Thursday AM (-20c) but valley temperatures should warm to -10C. Clouds will roll in mid- day with a few cm in the forecast.

Snowpack Summary

Wide spread wind effect above treeline has created wind slab on NE to SE aspects. Up to 65cm of snow sits over the Jan.17 surface hoar, especially prevalent between 1800-2000m. In shallower areas weak facets and depth hoar exist below the Dec 10 interface. In deeper snow packs this basal weakness is less pronounced.

Avalanche Summary

No new avalanches reported or observed today.
