Regions

Sugarbowl, Kakwa, McGregor, Renshaw, Robson.

New snow and strong winds will form fresh wind slabs at upper elevations.
Freezing levels are uncertain: Snow may fall as rain at treeline and below.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.
  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

On Thursday, several warming-induced wet loose and glide slab avalanches were reported in the McGregors up to size 3 on all aspects and elevations.

On Wednesday, several natural slab avalanches up to size 2.5 were reported.

Looking forward, natural avalanches are unlikely, but human triggering remains possible.

Snowpack Summary

2 to 15 cm of new snow is expected on Saturday. This will bury a thick melt-freeze crust that is currently capping the snowpack on all but potentially the highest northerly terrain above 2000 m.

The new snow is forecast to arrive with strong southwesterly winds and will be building fresh slabs on lee slopes at upper elevations.

The late January persistent weak layer, consisting of surface hoar/facets/crust, is currently buried 30 to 60 cm. This layer is now expected to be generally dormant due to the thick crust bridging overtop. Lingering concern for triggering this layer remains on steep, high alpine northerly slopes.

Weather Summary

Friday Night

Mostly clear skies. 1 to 2 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level dropping to 1600 m.

Saturday

Cloudy. 2 to 15 mm of precipitation as snow or rain at treeline, with lowest accumulations in the southern parts of the region. 60 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level between 1500 m to 1800 m.

Sunday

Mix of sun and clouds. 5 to 20 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1300 m.

Monday

Mix of sun and clouds. 1 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Wind slabs are most reactive during their formation.

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.
