Continuously assess conditions as you move through terrain, change your mindset to match the hazard at hand.

Glide slab releases continue to be reported, give these hazards a wide berth.

    Wind slabs may exist on all aspects due to variable wind direction. Wind slabs are more likely to be found on or near ridge crests.
    Dry loose avalanches are possible in steep terrain where the snowpack feels unconsolidated.

Avalanche Summary

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

Natural wind slab and dry loose avalanches up to size 2 continue to be reported in steep terrain.

Snowpack Summary

Wind has varied in direction over the past few days, wind slab could be found on all aspects as a result.

A 2 to 10 cm thick rain crust can be found down 60 to 80 cm at 1400 m and below. This layer is currently not a concern.

At 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

Saturday Night
Partly cloudy. 20 km/h west ridgetop wind. Treeline temperature -4 °C.

Sunday
Mix of sun and clouds. 1 to 4 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Monday

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • 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.
