Regions

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

New snow and strong winds are building reactive storm slabs.
Freezing levels are uncertain: Snow may fall as rain at lower elevations.

Confidence

Moderate

  • 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, with the forecast snow and wind building fresh storm slabs, we expect natural avalanches to be possible, and human-triggered avalanches to be likely on Sunday.

Snowpack Summary

Around 15 to 25 cm of new snow is covering a thick melt-freeze crust that exists up to around 2000 m and on all solar aspects. Some of the new snow may have fallen as rain at lower elevations. Forecast strong west and southwesterly winds will be building thicker and more reactive storm slabs on lee north and easterly slopes.

The late January persistent weak layer, consisting of surface hoar/facets/crust, is buried 40 to 70 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 above 2000 m.

Weather Summary

Saturday Night

Mostly cloudy. 5 to 20 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1700 m dropping to valley bottom.

Sunday

Mix of sun and clouds. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level rising to 1300 m.

Monday

Mix of sun and clouds. 0 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level rising to 1200 m.

Tuesday

Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level rising to 1300 m.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
