Sheltered areas will have good riding. Be sure to assess for wind-affected snow before committing to steep slopes.
20 to 50 cm of soft snow may be transported by north winds today. Previous winds varied; you may find wind slabs on any aspect in exposed terrain features.
On Sunday near Terrace, a natural size 2.5 wind slab avalanche 50 cm deep was observed on a northeast-facing, steep, alpine slope.
There was lots of travel in the Shames backcountry with no reports of avalanches or instability.
On Saturday there were also several size 1 and 2 wind slab avalanches in steep terrain on north- and south-facing slopes at treeline and above. Often, these avalanches failed about 30 cm deep on the melt-freeze crust described in the Snowpack Summary.
New snow, and the previous 20 to 50 cm of soft snow, could be transported by north winds today. At upper elevations, previous winds were from the south, so you may find wind slab in any exposed, lee terrain features.
This overlies previous hard surfaces or a melt-freeze crust that extends up to 1800 m.
The remainder of the snowpack is reportedly strong with various hard crusts. Check out this MIN report describing conditions in the backcountry near Shames.
Snow depths vary throughout the region, ranging from 150 to 300 cm at treeline and tapering rapidly below.
