Preliminary reports from Sunday indicate small (size 1) wind slabs were reactive on south-facing slopes in the immediate lee of ridgetops.On Saturday, several small (size 1) wind slabs were triggered in northern parts of the region. Loose dry sluffing was also reported in steep terrain.On Friday, a size 1.5 wind slab was remotely triggered as a skier approached a steep south-facing slope north of Pemberton. The slab was 10-40 cm deep and had recently been loaded by north winds. On Thursday, a slab avalanche was reported in the Duffey area on northwest aspect at 1900 m (see MIN report here).

Friday's storm delivered 10-15 cm in northern parts of the region and 15-25 cm in southern parts of the region. Recent wind has formed isolated pockets of slabs in exposed terrain, while sheltered areas have cold low density snow. The top 20 to 40 cm of the snowpack consists of low density snow that is gradually bonding to old hard surfaces that include crusts and wind-packed snow. Low-density snow may sluff easily from these hard surfaces. In some isolated features, the snow has settled into thin slabs above these hard surfaces and produced small avalanches with minimal destructive potential. The remainder of the snowpack is generally well-settled.
