Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Start on small, low angled features to assess how the snow is bonding.

Recent snow will take time to bond with the old surface.

Confidence

Moderate

Avalanche Summary

Sunday: A natural avalanche cycle of large (size 1 to 2.5) was reported in the region on all aspects at all elevations

Saturday: Avalanches reported in the pine pass area. Natural and remote triggers in a variety of terrain and at all elevations. Check out this MIN for more information.

Friday: Touchy storm slab conditions were reported in the Pine Pass area with remote triggering of small steep features .

Snowpack Summary

New snow continues to accumulate across the region adding up to 15 - 30 cm of new snow, accompanied by strong southwest alpine winds. This has created deep deposits of new snow and fresh wind slabs in exposed terrain.

New snow has buried older wind-affected surfaces in exposed terrain, or surface hoar, and a faceted upper snowpack in sheltered areas. Layers formed during dry conditions in January are buried approximately 30 to 100 cm below the surface. These consist of surface hoar, faceted grains, and/or a hard crust, and could become a source of instability with the addition of the new snow and warming temperatures.

The lower snowpack is generally well-settled.

Wednesday

Mix of sun and cloud with up to 5 cm of snow. 40 to 80 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2000 m.

Thursday

Mostly cloudy with 5 to 15 cm of snow. 20 to 50 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1700 m.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.

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.
