Avalanche Forecast
Regions: Glacier.
Weather Forecast
Cloudy with sunny periods today, with light W alpine winds and freezing levels rising to 1900m. Monday will see much of the same with some isolated flurries resulting from the unstable air mass over BC.
Snowpack Summary
10-15cm of new snow at treeline. Settling storm snow in the top 60cm overlies a series of crusts on most aspects up to 1900m. Moderate SW winds at tree-line and alpine have formed wind slabs on lee features. Cold, dry snow can be found on northerly slopes while solar aspects rapidly become moist with sunshine. Huge cornices line the upper ridges.
Avalanche Summary
A field team encountered touchy surface wind slabs in northerly lee aspects at 2200m yesterday. The 10-15cm soft slabs were easily failing with ski cuts and running fast on a temp crust. On Friday, several large avalanches from Mt Macdonald to size 3.5 were observed running to the valley floor, likely cornice triggered.
Confidence
Timing or intensity of solar radiation is uncertain
