The natural avalanche cycle is expected to taper off but the new slab formed by storm snow over the basal facets will likely continue to create large avalanches for some time. Avoid all avalanche terrain for the next while until things settle down!
Summary
Weather Forecast
Moderate to strong W winds with strong gusts are expected to continue for the next 2 days with cloudy skies. The precipitation has ended. Alpine temperatures will be around -7C with overnight lows of -10. Winds will abate by Thursday and skies will become a mix of sun and cloud.
Snowpack Summary
Up to 80 cm of storm snow has fallen over the last few days, combined with very strong winds. Deep storm slabs have formed from new snow and wind loading; in excess of 120 cm in leeward areas. These slabs are overloading a weak, facetted snowpack. The precipitation has ended, but strong gusty West winds are expected to continue for the next 2 days.
Avalanche Summary
Large avalanches to size 3 continue to occur with some running full path. A size 2 in White Rabbit (near Louise ski area) released to ground, causing several sympathetic size 1's. Numerous human triggered avalanches were reported adjacent to ski areas including Ptarmigan Chutes today and Maintenance Cliffs and a close call on
Wawa Ridge yesterday.
