Avalanche Forecast

Numerous natural and rider triggered wet loose avalanches up to size 2 were reported on sunny aspects on Monday.

A sled triggered size 1 wind slab was also reported on a northeast aspect at treeline.

Strong solar radiation has formed a surface crust everywhere except true north facing terrain at upper elevations.

Recent wind has formed wind slabs on lee features at treeline and above.

A widespread crust with facets above is down 60 to 110 cm. This layer is unlikely to human trigger in areas where a thick crust below the recent snow is present. However, steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places where it may be possible to trigger this layer with large loads.

Tuesday Night

Mostly cloudy with isolated flurries, 0 to 15 cm snow. 30 to 40 km/h southwest ridgetop wind. Treeline temperature 1° C. Freezing level 2100 m.

Wednesday

Mix of sun and cloud with isolated flurries, 0 to 5 cm snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -2° C. Freezing level 1800 m.

Thursday

Cloudy with isolated flurries, 0 to 5 cm snow. 10 to 20 km/h east ridgetop wind. Treeline temperature -3° C. Freezing level 1700 m.

Friday

Mix of sun and cloud. 10 to 20 km/h east ridgetop wind. Treeline temperature 0° C. Freezing level 2000 m.

• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
