Up to 20 cm of snow will be redistributed by moderate winds building fresh wind slabs in lee terrain features.
Shooting cracks are a good indicator of slab formation, test the snow as you go.
New snow, coupled with wind will continue to build wind slabs in lee terrain features at upper elevations. They may be surprisingly reactive, particularly where they sit over surface hoar or a crust.
On Saturday, numerous dry loose avalanches were reported in the Kicking Horse backcountry.
Going forward we expect wind slabs to be reactive where they have buried a surface hoar layer.
Up to 10 cm of new snow brings recent storm snow to roughly 10 to 20 cm. This new snow buries various surfaces of crust, surface hoar and wind affected snow.
Moderate wind from the south will redistribute new snow at upper elevations. Storm slabs will be especially sensitive where they are forming over a surface hoar or crust layer.
