continuously assess conditions as you move through terrain

Remember that small avalanches can have big consequences in extreme terrain.

Over the past couple days natural, dry loose avalanches up to size 1.5 were observed on steep south facing terrain.

A few skier triggered dry loose avalanches up to size 1 were also reported. These avalanches were in steep terrain on north aspects.

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.

Monday Night

Clear skies. 10 to 25 km/h northwest ridgetop wind. Treeline temperature -28 °C.

Tuesday

Sunny. 10 to 25 km/h northwest ridgetop wind. Treeline temperature -20 °C.

Wednesday

Mostly sunny. 10 to 30 km/h northwest ridgetop wind. Treeline temperature -20 °C.

Thursday

Mostly sunny. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -10 °C, potential for temperature inversion with warmer temperatures in the alpine.

• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Carefully evaluate steep lines for wind slabs.
