Lingering reactivity in wind slabs remains a concern.

Use caution around ridgelines, mid slope rollovers, and cross loaded terrain features.

High

• Confidence is due to a stable weather pattern with little change expected.
• Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

On Saturday, size 1.5 loose dry avalanches were reported from steep alpine terrain features. Several large wind slabs have been observed over the last week, on northeast, east, and south facing slopes. These avalanches failed on a layer of facets beneath recent snow.

5 to 15 cm of recent snow overlies heavily wind affected snow in exposed areas. A layer of sugary facets is buried around 50 cm deep and is slowly gaining strength. Below 1300 m, a near-surface crust is present.

The mid and lower snowpack have no layers of concern. Snowpack depths are generally around 150-200 cm deep at treeline.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Avoid slopes that sound hollow or drum-like.
• Make observations and continually assess conditions as you travel.
