Highlights

The season is off to a great start in the region

Make assessments as you move through terrain

Up high small wind slabs exist, lower down early season hazards could be just below the surface

    Wind slabs may exist on all aspects due to variable wind direction over the past couple days. Wind slabs are more likely to be found on or near ridge crests.

Moderate

Avalanche Summary

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

Natural wind slab and dry loose avalanches up to size 1.5 continue to be reported in steep terrain.

Snowpack Summary

The winter is off to a great start in the region!

Around 60 cm of recent storm snow has been redistributed on to west facing slopes by easterly wind.

A 2 to 10 cm thick rain crust can be found down 40 to 80 cm at 1400 m and below. This layer is currently not a concern.

Above treeline there is an above 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.

Weather Summary

Wednesday Night

Mix of cloud and clear skies with trace amounts of snow. 5 to 20 km/h north alpine wind. Treeline temperature -10°C, potential for temperature inversion with colder temps at valley bottoms.

Thursday

Mostly sunny with trace amounts of snow possible. 5 to 15 km/h north alpine wind. Treeline temperature -7°C, potential for temperature inversion with colder temps at valley bottoms.

Friday

Mix of sun and cloud. 10 to 25 km/h north alpine wind. Treeline temperature -5°C, potential for temperature inversion with colder temps at valley bottoms.

Saturday

Mix of sun and cloud with trace amounts of snow possible. 15 to 30 km/h southwest alpine wind. Treeline temperature -6°C.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be cautious of buried obstacles, especially below treeline.
