Regions

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

Assess the bond between wind slabs and the underlying crust before committing to steep terrain.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

A few small dry loose avalanches were reported over the weekend involving 30 cm of low-density snow above a crust. Otherwise, recent activity is limited to older wind slabs from last week’s storm.

Wind slabs may remain reactive longer than usual due to poor bonding to the crust.

Snowpack Summary

5 to 30 cm of low-density snow fell over the weekend, now sitting over older wind-affected snow.

A thick crust from the mid-March atmospheric river is buried 30 to 60 cm deep and extends up to about 1500 m.

Below the crust, the snowpack is strong and well bonded.

Weather Summary

Monday Night

Mostly clear skies. 30 km/h west ridgetop wind. Treeline temperature -10 °C.

Tuesday

Mix of sun and clouds. 0 to 1 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -6 °C.

Wednesday

Mostly cloudy. 2 to 3 cm of snow. 20 km/h southeast ridgetop wind. Treeline temperature -5 °C.

Thursday

Mix of sun and clouds. 1 to 2 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Investigate the bond of the recent snow before committing to your line.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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.
