Snowpack Summary

40 to 80 cm of recent snow has been redistributed by strong south to southwest winds. Wind effect is widespread in the alpine as well as isolated features at treeline elevations. A thin (1 to 2 mm) freezing-rain crust under the new snow has been reported in the mountains surrounding Revelstoke. Below this, the snowpack is generally well-settled and strong.
