Regions

Kootenay Boundary, Purcells, Bonnington, Grohman, Kootenay Pass, Norns, Ymir, Crawford, Moyie, Kokanee, Retallack, Valhalla, Whatshan.

Recent snow, since Christmas, may not be bonding well to the underlying crust in some areas.

Confidence

High

  • Confidence is due to a stable weather pattern with little change expected.

Avalanche Summary

Numerous small (size 1 to 1.5) skier-triggered avalanches occurred on Monday, failing on the Dec. 25 crust. Most of these avalanches occurred on northerly terrain around treeline elevations.

Snowpack Summary

In exposed alpine and treeline areas, wind-affected surfaces persist. On south-facing slopes at higher elevations, a thin sun crust is likely to form overnight.

Recent storm snow continues to settle and bond to a crust buried on Dec. 25, which is thin or absent in alpine terrain but thicker and more widespread at treeline and below.

The mid and lower snowpack is generally well-bonded and consolidated, with multiple crust layers present.

Weather Summary

Wednesday Night
Clear skies. 20 km/h southwest ridgetop wind. Treeline temperature -1 °C, with a chance of above-freezing temperatures in the alpine.

Thursday
Cloud building throughout the day. 20 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Friday
Mostly cloudy. 5 to 15 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Saturday
Mostly cloudy. 15 to 30 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1600 m.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Be careful as you transition into wind-affected terrain.

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.
