Regions

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

Sunshine can give a false sense of security, but 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 about how the timing or intensity of solar radiation will affect the snowpack.

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 120 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 down to 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

Friday Night

Cloudy. 1 to 2 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -13 °C.

Saturday

Mostly sunny. 40 km/h west ridgetop wind. Treeline temperature -10 °C.

Sunday

A mix of sun and clouds. 1 to 3 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -6 °C.

Monday

Cloudy. 15 to 25 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
  • 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.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
