Snowpack Summary
30 to 70 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 settled and strong.
Problems
Wind Slabs
Recent strong southwest winds have produced fresh wind slabs at higher elevations. You may find touchy slabs in lee and cross-loaded terrain features near ridges.
Watch out for wind slabs, especially in steep slopes or depressions near ridges.Look for signs of instability such as whumpfs, hollow sounds, shooting cracks, or recent avalanchesCornices may be touchy; stay well-back on ridges and avoid travelling beneath them.
