Regions

Boundary, Ningunsaw, Ningunsaw, Ningunsaw.

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

Confidence

Moderate

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

Friday Night

Mix of clear sky and cloud. 5 to 10 km/h east alpine wind. Treeline temperature -6°C.

Saturday

Sunny. 5 to 10 km/h east alpine wind. Treeline temperature -6°C.

Sunday

Cloudy with around 5 cm of snow. 15 to 30 km/h southwest alpine wind. Treeline temperature -4°C.

Monday

Cloudy with up to 15 cm of snow at treeline and above. 20 to 40 km/h southwest alpine wind. Treeline temperature -1°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be cautious of buried obstacles, especially below treeline.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Make observations and continually assess conditions as you travel.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
