Avalanche Forecast

Over the past couple days natural and human triggered dry loose avalanches up to size 1 were observed on steep terrain. Natural icefall was also observed entraining mass, producing a size 2 dry loose avalanche and not a slab.

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.

Tuesday Night

Clear periods. 10 to 15 km/h northwest ridgetop wind. Treeline temperature -28 °C.

Wednesday

Sunny with some cloud. 15 km/h northwest ridgetop wind. Treeline temperature -17 °C.

Thursday

A mix of sun and cloud. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -20 °C.

Friday

A mix of sun and cloud. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -12 °C.

• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Carefully evaluate steep lines for wind slabs.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
