Regions

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

Avoid avalanche terrain during periods of heavy snowfall.

Avalanche activity will increase as the storm rolls in.

Stick to low elevations and gentle terrain with low consequence.

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

No avalanche activity has been reported in the past few days. Poor visibility has restricted field observations.

Looking forward, natural avalanche activity is expected as new snow accumulates and the wind picks up over the coming days.

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

Snowpack Summary

By Wednesday afternoon, an additional 25 to 40 cm will be added to the current snowpack. This overlies old settling snow and hard wind-affected snow on all aspects, including lower elevations below treeline in some areas. Strong to extreme southwest winds will redistribute this new snow into deeper deposits on lee slopes.

On some ridgetops, the previous wind stripped the snow in wind-exposed terrain down to the early-February melt-freeze crust. In wind-sheltered terrain, around 60 to 90 cm of snow sits on top of this crust. It seems well-bonded and is not considered a problem at this time.

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

Weather Summary

Tuesday Night

Cloudy. 15 to 30 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday

Cloudy. 15 to 25 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Thursday

Cloudy. 10 to 25 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Friday

Cloudy. 2 to 5 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -12 °C.

Terrain and Travel Advice

  • Avoid areas with overhead hazard.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Watch for fresh storm slabs building throughout the day.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
