High avalanche danger. Avoid avalanche terrain and exposure to overhead hazards like cornices and runout zones.

Moderate

• We are uncertain about how the snowpack will react to the forecast weather.

Several slab and wet loose avalanches were reported on Monday. We expect avalanche activity to continue throughout the forecast period.

Rain continues to fall up to 2000 m in some areas, resulting in wet, unstable snow below this elevation. Above the rain line, new snow combined with strong south to southwest winds are building slabs in lee terrain.

A widespread crust is buried 20–60 cm deep below 2100 m. Beneath this, the snowpack is generally well settled with no significant layers of concern.

Tuesday Night

Cloudy. 30 to 40 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2000 m.

Wednesday

Cloudy. 10 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2000 m.

Thursday

Cloudy. 30 to 50 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1800 m.

Friday

Cloudy. 45 to 70 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1900 m.

• Loose avalanches may start small, but they can grow and push you into dangerous terrain.
• Keep in mind that the high density of wet avalanches can make them destructive.
• As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
