Adjust your approach to terrain as you gain elevation

Wind slabs are the primary hazard up high and early season hazards are the primary down low

A size 1.5 skier triggered avalanche was reported on Wednesday on a north east aspect. This avalanche ran on the surface hoar described in the snowpack summary. Check out this Mountain Information Network report for more details.
A couple of small, natural wind slab avalanches were observed on westerly aspects by our field team on Thursday. These avalanches likely occurred over the past 24 to 48 hours.

5 to 10 cm of recent storm snow overlies  old wind affected snow, wind slab and the early November rain crust depending on aspect.

On sheltered features a new surface hoar layer is down up to 20 cm. The early November crust is buried around 60 cm deep and may have small facets above it in these locations.

At treeline there is a snowpack depth of 60 to 80 cm. Snowpack depth tapers with elevation to around 30 cm at valley bottoms. Many early season hazards are just below the surface below treeline.

Thursday Night

Mix of cloud and clear sky with trace amounts of snow possible. 10 to 30 km/h southeast alpine wind. Treeline temperature -8°C.

Friday

Mix of sun and cloud. 15 to 35 km/h southeast alpine wind. Treeline temperature -8°C.

Saturday

Mix of sun and cloud with 1 to 3 cm of snow. 10 to 20 km/h southeast alpine wind. Treeline temperature -8°C.

Sunday

Cloudy with up to 5 cm of snow. 30 to 50 km/h southwest alpine wind. Treeline temperature -2°C.

• Be careful as you transition into wind-affected terrain.
• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Be cautious of buried obstacles, especially below treeline.
