Kootenay Boundary

Continuously assess conditions as you move through terrain.

Avalanches are possible where the upper snowpack feels "stiff and slabby".

On Tuesday, a few isolated wind slabs up to size 1 were human triggered from steep northeast facing terrain at treeline.Rider triggering is possible where a stiffer slab exists above the late January buried weak layers and sluffing will be seen in steep terrain features.

Exposed terrain in the alpine and treeline is variably wind-affected. In sheltered terrain a layer of surface hoar or a sun crust can be found on or just below the surface.

20 to 60 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.

The mid and lower snowpack is generally well settled.

Wednesday Night

Clear periods. 15 km/h northwest ridgetop wind. Treeline temperature -18 °C.

Thursday

A mix of sun and cloud with a trace of new snow. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -9 °C.

Friday

Cloudy with new snow 2 to 8 cm. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -9 °C.

Saturday

Cloudy with sunny periods and isolated flurries. 10 km/h southwest ridgetop wind. Treeline temperature -10 °C.

• Be careful as you transition into wind-affected terrain.
• Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
