Regions

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

Stormy weather will continue to create very dangerous avalanche conditions.

Avoid avalanche terrain during periods of heavy loading from new snow or wind.

Confidence

Moderate

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

Avalanche Summary

Poor visibility restricted field observations, but two natural wind slab avalanches (size 2) were observed on north-facing terrain at treeline near Kakwa. Numerous signs of instability were observed, such as cracking on small convex rolls and sluffing on steep terrain at lower elevations.

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

Snowpack Summary

On Wednesday, another 20 to 40 cm of snow had fallen, bringing the totals to 30 to 60 cm since Monday. 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 near ridgetops.

Strong to extreme southwest wind has redistributed this new snow into deeper deposits on lee slopes. The previous wind had stripped the snow in wind-exposed terrain down to the early-February melt-freeze crust.

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

Weather Summary

Wednesday Night

Cloudy. 10 to 25 cm of snow. 80 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Thursday

Cloudy. 5 to 15 cm of snow. 70 km/h west ridgetop wind. Treeline temperature -4 °C.

Friday

Cloudy. 5 to 10 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -10 °C.

Saturday

A mix of sun and clouds. 40 km/h west ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Avoid areas with overhead hazard.
  • Avoid avalanche terrain during periods of heavy snowfall.
  • Avoid the runout zones of avalanche paths. Avalanches could run full path.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.

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.
