Wind slabs may be reactive to human triggering at upper elevations. Use caution in lee and cross-loaded terrain near ridge crests.
Summary
Confidence
High - The snowpack structure is generally well understood.
Weather Forecast
FRIDAY NIGHT: Cloudy with snowfall, accumulation 2 to 5 cm, 15 to 35 km/h southwest wind, alpine temperature -6 C.
SATURDAY: Cloudy with light snowfall, up to 5 cm of accumulation, 15-40 km/h south winds, alpine temperature rising to -3 C. Freezing level reaching 1500 m.
SUNDAY: Cloudy with snowfall, 5-10 cm of accumulation. 10-30 km/h northwest winds, alpine temperature rising to -3 C. Freezing level reaching 1700 m.Â
MONDAY: Cloudy with snowfall, 5 cm accumulation. 20-40 km/h northwest winds, alpine temperature rising to -3 C. Freezing level reaching 1600 m.
Avalanche Summary
On Thursday, a natural wind slab (size 2) was observed in the alpine from southwest winds redistributing new snow.
Widespread loose wet and wet slab avalanche activity occurred during the warm-up on Wednesday.Â
Looking forward, riders may be able to trigger wind slabs in lee terrain features in steep alpine terrain.
Snowpack Summary
Up to 20 cm of recent snowfall and southwest winds have formed wind slabs in lee terrain features in the alpine. This new snow tapers rapidly with elevation. Below 2300 m, a melt-freeze crust can be found with moist snow below.
There are no deeper concerns at this time.
Terrain and Travel
- Carefully evaluate steep lines for wind slabs.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Problems
Wind Slabs
Wind slabs may be found in wind-loaded terrain at high elevations, formed from recent strong southerly wind.
Aspects: North, North East, East, West, North West.
