KT,
Avalanche Canada
Good riding to be had on sheltered slopes. Exposed areas are wind affected and wind slabs may be triggerable.
Summary
Confidence
Moderate
Avalanche Summary
Several natural wind slab avalanches to size 2 were observed in the alpine on Sunday. A nearby ski hill triggered a size 2 persistent slab avalanche on a facet crust layer on Saturday with explosives.
Snowpack Summary
Moderate westerly winds have built windslabs in the alpine and at treeline in exposed areas. 30-40 cm of unconsolidated snow exists in sheltered slopes. This overlies older windslabs and faceted snow above the Feb 3rd crust. Below this, the snowpack is settled with a crust/facet complex near the ground. Average snowpack depths are between 100 - 150 cm.
