Heightened avalanche conditions remain where slabs have formed above a weak layer buried deep in the snowpack.
Evaluate slopes individually before committing to the terrain.

Terrain and Travel Advice:
  • Keep in mind the crust offers an excellent bed surface for avalanches.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
Persistent Slab

This problem is most likely where weak sugary snow is starting to form a weak layer above the early February crust. Avalanches on this layer could propagate wider and run farther than expected.

Avalanche Summary

On Monday, a group of skiers triggered a size 2, persistent slab avalanche in the Ladder Chutes, close to Fernie. For more details check out the MIN post.

A few natural loose dry avalanches were observed up to size 1 in steep terrain.

Snowpack Summary

Alpine and open treeline terrain is generally wind-affected. In wind sheltered areas, 30 to 60 cm of settling snow sits above a 10-20 cm thick, rain crust that formed in early February. In some areas, weak, sugary crystals (facets) are starting to form above this crust.

Weather Summary

Tuesday Night

Cloudy with 1 to 5 cm of snow. 10 to 25 km/h southwest ridgetop wind. Treeline around -2 °C. Freezing level to 1000 m.

Wednesday

Partly cloudy. 10 to 25 km/h southwest ridgetop wind. Treeline high around 0 °C. Freezing level rising to 1600 m.

Thursday

Mostly cloudy with 0 to 2 cm of snow. 20 to 30 km/h west ridgetop wind. Treeline temperature around 0°C. Freezing level at 1800 m.

Friday

A mix of sun and cloud. 20 to 30 km/h southwest ridgetop wind. Treeline temperature around 0°C. Freezing level at 1900 m.

More details can be found in the Mountain Weather Forecast.

Confidence: moderate
Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.

Heightened avalanche conditions remain where winds formed slabs above a weak layer buried deep in the snowpack. Investigate the bond of slabs to surfaces below before committing to a slope.

Terrain and Travel Advice:
  • Be mindful that deep instabilities are still present and have produced recent large avalanches.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Keep in mind the crust offers an excellent bed surface for avalanches.
Persistent Slab

Persistent slabs may be reactive to human triggering in areas, where winds have formed a slab above a layer of facets overlying a crust. Avalanches on this layer could propagate wider and run farther than expected.

Avalanche Summary

On Monday, explosives control in the region produced a size 2 persistent slab avalanche that failed on faceted snow above the early February rain crust.

Snowpack Summary

Previous moderate to strong winds varying in direction, formed wind affected surfaces on all aspects and at all elevations. In terrain sheltered from the wind, expect 30 to 50 cm of snow over the thick rain crust that formed in early February. In some areas, weak, sugary facets have formed above this crust.

At treeline and below, a sun crust may be found on the surface on aspects that face the sun.

Weather Summary

Tuesday Night

Mainly cloudy. 10 to 25 km/h southwest ridgetop wind. Treeline around -2 °C. Freezing level to 1500 m.

Wednesday

Partly cloudy. 10 to 25 km/h southwest ridgetop wind. Treeline high around -1 °C. Freezing level rising to 1700 m.

Thursday

Mostly cloudy with 0 to 2 cm of snow. 20 to 30 km/h west ridgetop wind. Treeline temperature around 0°C. Freezing level at 1800 m.

Friday

A mix of sun and cloud. 20 to 30 km/h southwest ridgetop wind. Treeline temperature around 0°C. Freezing level at 1900 m.

Terrain and Travel Advice:
  • Conditions may have improved, but be mindful that deep instabilities are still present.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Potential for wide propagation exists, fresh slabs may rest on surface hoar, facets and/or crust.
Persistent Slab

Persistent slabs may be reactive to human triggering in areas, where winds have formed a slab above a layer of facets overlying a crust. Avalanches on this layer could propagate wider and run farther than expected.

Avalanche Summary

On Monday, a few natural and human-triggered wind slab avalanches were observed up to size 1.5 in the Okanagan. It is suspected that these avalanches failed on a weak layer of facets overlying a crust.

Through the weekend several, human-triggered wind slab avalanches up to size 2, were reported in the alpine and open treeline terrain.

Snowpack Summary

Alpine and open treeline terrain are generally wind-affected, with reactive wind slabs in some places. At the surface in most areas, surface hoar is forming in wind protected terrain. Around Nelson and in the Valhallas, small (5 mm) surface hoar (weak, feathery crystals) have been reported to be buried 15-20 cm below the snow surface.

Facets (weak, sugary crystals) are starting to form above a thick rain crust that was buried in early February. This crust is now 30 to 50 cm below the snow surface.

The mid and lower snowpack presents as settled, with snowpacks depths decreasing rapidly on terrain below 1000 m in elevation.

Weather Summary

Tuesday Night

Cloudy with 1 to 2 cm of snow. 10 to 25 km/h southwest ridgetop wind. Treeline temperature around -4 °C. Freezing level 1000 m.

Wednesday

Mostly cloudy with 1 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature around 0°C. Freezing level rises to 1600 m through the day.

Thursday

Mostly cloudy with 1 cm of snow. 10 to 20 km/h west ridgetop wind. Treeline temperature around 0°C. Freezing level at valley bottom overnight, rising to 1600 m through the day.

Friday

A mix of sun and cloud. 10 to 25 km/h southwest ridgetop wind. Treeline temperature +1°C. Freezing level rises to 1800 m.

Confidence: high
The number, quality, or consistency of field observations is good, and supports our confidence.
