Significant changes to the Avalanche hazard as new storm snow is loading and reactive on lee aspects, especially at treeline and above. Careful assessment is required for riders and climbers as conditions are far more hazardous than they have been so far this year.
The current storm may produce a running total of up to ~20cm of new snow by Wednesday. Southwest winds are blowing new snow into slabs that is likely to be triggered by riders.
Recent HST is being aggressively redistributed in the Icefields by moderate S/SW winds over an existing soft wind slab. Below that, a firm and supportive mid-pack is found throughout the forecast region. Nov 10 MFcr, ~30cm off the ground, slowly faceting. HS ranges from 60 to 110cm at treeline in the Icefields. The Bald Hills area has less snow with an average HS of 60cm.
