Two skier triggered wind slab avalanches were reported in the region on Monday. Both were size 1.5 in the treeline elevation. One was on a Southeast aspect and the other on a North aspect.

One skier controlled avalanche was also reported on Monday Near RMR. This was a size one wind slab on a North aspect at treeline.

10 to 30cm of low density snow fell Tuesday morning with the largest amounts in the Selkirks. This overlies up to 30cm of old storm snow that was redistributed by moderate Southeast winds.

The defining feature of the snowpack is a widespread prominent crust that reaches as high as 2200 m in the alpine now sits 50-80 cm below the surface. In many places, overlying snow is well-bonded to the crust but in others weak faceted grains have been observed growing above it.

Average snowpack depth at treeline is 230cm.

• Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
• Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
• In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
