A slow trickle of precipitation will effect the Little Yoho region over the next three days (~30cm), improving the ski quality. Watch for the development of windslabs in the alpine.

Summary

Weather Forecast

Between now and Wednesday expect up to 30cm of new snow in the Little Yoho region. Light to moderate West winds will create windslabs over this time period in lee areas in the alpine.

Snowpack Summary

Up to 20cm of low density snow in the last 48 hours. The Jan 30 melt/freeze crust can be found up to 2300m (higher on solar aspects). In isolated areas we expect the Dec. 18 surface hoar layer down approximately 50-70cm to remain, but triggering is unlikely.
