Regions

Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson.

Dangerous avalanche conditions remain.

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

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Numerous natural storm slabs and wind slabs avalanches (up to size 3) were reported from all elevations and all aspects from the heavy storm on Thursday. Field observations remain limited to determine details.

Looking forward, avalanche activity will remain sensitive to human triggering over the coming days, as natural avalanches will taper off.

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

Snowpack Summary

90 to 140 cm of recent snow overlies previously wind-affected surfaces or a solid melt-freeze crust. Strong to extreme westerly wind redistributed this recent snow farther downslope than normal, forming reactive slabs at all elevations.

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

To read about conditions in Kakwa on Thursday, see this MIN report from the Avalanche Canada North Rockies field team.

Weather Summary

Saturday Night

Partly cloudy. 60 km/h west ridgetop wind. Treeline temperature -10 °C.

Sunday

Mostly cloudy. 70 km/h west ridgetop wind. Treeline temperature -6 °C.

Monday

Mostly cloudy. 10 to 25 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -4 °C.

Tuesday

Mostly cloudy. 15 to 30 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Recent strong wind means wind slabs may be found farther downslope than expected.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
