Wind slabs may be reactive to human triggering in the alpine.
Assess snowpack conditions as you travel through the terrain.
Rider triggerable pockets of wind slab may still be found in exposed terrain.
Where slab properties are not observed dry loose avalanches are possible.
On Tuesday a few human triggered wind slabs were reported up to size 1 in north-facing, alpine terrain.
If you head into the backcountry consider submitting a MIN post!
Exposed terrain in the alpine and treeline is generally wind-affected. In sheltered terrain 10 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects.
A weak layer of facets from early December is 60 to 120 cm deep.
The base of the snowpack consists of a thick crust with facets or depth hoar in many areas.
