Regions

North Rockies, Sugarbowl, East Kakwa, McGregor, Pine Pass, Tumbler.

Wind slabs may remain triggerable on isolated lee slopes.
Use normal caution and check all steep open slopes for slabs before committing to them.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

On Thursday, explosive control near Pine Pass produced several cornice falls and entrained loose snow in the size 1.5 to 2.5 range.

Several size 1.5-2 wind slabs occurred on southwesterly slopes in the Pine Pass during Tuesday and Wednesday's strong winds.

Shooting cracks were also observed at Morfee on Tuesday and Pine Pass on Friday.

Looking forward, triggering avalanches is unlikely, except for on steep wind-loaded slopes in isolated areas.

Snowpack Summary

Previous strong winds funnelled deep into valleys creating extensive wind effect on all aspects. This included even lower elevations with openings below treeline in some areas. Wind slabs developed on leeward slopes and crossloaded features, which are likely stubborn to trigger by now.

On some ridgetops, the wind stripped the snow in wind-exposed terrain down to the early-February melt-freeze crust. In wind-sheltered terrain, around 30 to 60 cm of snow overlies this crust. It seems well-bonded and is not considered a problem at this time.

The remainder of the snowpack is consolidated with no layers of concern.

Weather Summary

Saturday Night
Mostly cloudy. 0 to 2 cm of snow. 20 km/h southeast ridgetop wind. Treeline temperature -18 °C.

Sunday
Mostly cloudy. 0 to 5 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature -16 °C.

Monday
Mostly cloudy. 0 to 4 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Tuesday
Mostly cloudy. 1 to 5 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -11 °C.

Terrain and Travel Advice

  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.

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.
