Regions

Crowsnest North, Crowsnest South.

Wind slabs likely linger in higher terrain, watch for changing conditions as you shift aspect and elevation.

Confidence

Moderate

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

Avalanche Summary

Loose avalanches were reported on Sunday to size 1.

Looking forward, human triggered avalanches are possible in wind loaded features.

Snowpack Summary

Strong winds have redistributed recent light snowfall at upper elevations over hard surfaces or a crust. At lower elevations, rain has created a supportive surface crust.

A persistent weak layer of surface hoar or facets and a crust is buried 30 to 50 cm deep. Avalanches on this layer are thought to be unlikely.

The mid and lower snowpack are well settled.

Weather Summary

Monday Night
Mostly cloudy. 1 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Tuesday
Mostly cloudy. 1 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -11 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Thursday
Mostly cloudy. 15 to 30 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Although avalanches are unlikely when a hard crust exists on the snow surface, the crust may pose a slip and fall hazard.

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.
