Avalanche Forecast

Moderate

On Friday, both natural and explosive controlled large (size 2) wind slab avalanches have been reported at elevations above 2200 m and on north aspect terrain. On Thursday extensive explosive control at a number of professional operations, produced large both wind and storm slab avalanches up to size (2.5).

10-25 cm of recent new snow has covered weak, faceted snow in many areas and wind-affected surfaces in open areas at all elevations.

A layer of surface hoar is found down 70 cm in sheltered, north-facing terrain. This layer appears as a sun crust on south-facing slopes. As temperatures slowly warm expect this layer to become reactive to human triggering.

A thick crust deep in the snowpack largely protects any weak layers further down in the snowpack from being triggered.

Saturday Night

Mainly cloudy. 1 to 5 cm of snow expected. Light to moderate southwest ridgetop wind. Treeline temperature around -5 °C.

Sunday

Mainly cloudy. 1 to 5 cm of snow expected. Light southwest ridgetop wind. Treeline temperature around -1 °C.

Mainly cloudy. 1 to 5 cm of snow expected. Light southwest ridgetop wind. Treeline temperature around 0 °C.

Mainly cloudy. 1 to 2 cm of snow expected. Light southwest ridgetop wind. Treeline temperature around 0 °C.

• Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
