Boundary

Stick to terrain sheltered from the wind where you'll find the softest snow and the lowest avalanche danger.

Looking forward to Monday, we expect that human triggered wind slab avalanches will be likely in wind exposed terrain.

Natural, glide slab avalanches up to size 2.5 have been recently observed throughout the region. These hazards should be given a wide berth.

Up to 20 cm of new snow and moderate to strong southwest wind may be forming reactive wind slabs on leeward slopes.

Wind has varied in direction over the past few days. Expect most exposed slopes to be wind-affected.

A 2 to 10 cm thick rain crust can be found down 60 to 90 cm at 1400 m and below. This layer is currently not an avalanche concern.

At treeline there is an average snowpack depth of 300 cm. Snowpack depth tapers with elevation to around 50 cm at valley bottoms. Many early season hazards are just below the surface below treeline.

Sunday Night
Cloudy. 10 cm of snow at treeline. 30-55 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Monday
Mostly cloudy. 4 to 7 cm of snow at treeline. 30-55 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Tuesday
Mostly cloudy. 1 cm of snow at treeline. 20 km/h west ridgetop wind. Treeline temperature -3 °C.

Wednesday
Mix of sun and clouds. 4 to 10 cm of snow at treeline. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

• Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
• Be cautious of buried obstacles, especially below treeline.
• Make observations and continually assess conditions as you travel.
