Regions

North Rockies, East Kakwa, Tumbler.

Dangerous avalanche conditions remain.

Rider-triggered avalanches are likely, so choose conservative terrain and route selection.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

There were no new avalanches to report in the last few days, but poor visibility restricted field observations since Tuesday.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

20 to 40 cm of recent snow overlies wind-affected surfaces or old settling storm snow. Strong to extreme westerly wind redistributed this new snow, farther downslope than normal, forming slabs down to treeline.

This overlies old settling snow in wind-sheltered terrain, hard wind-affected snow in open areas and/or a solid melt-freeze crust in wind-exposed terrain.

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

Weather Summary

Saturday Night

Clear skies. 70 km/h west ridgetop wind. Treeline temperature -11 °C.

Sunday

Mostly cloudy. 90 km/h west ridgetop wind. Treeline temperature -7 °C.

Monday

Mostly cloudy. 1 to 10 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -5 °C.

Tuesday

Mostly cloudy. 3 to 4 mm of precipitation as snow or rain at treeline. 50 km/h southwest 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.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.

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.
