Regions

South Okanagan, Shuswap, North Okanagan.

New snow has bonded poorly to old surfaces. Carefully manage sluffing in steep terrain and avoid exposure to cliffs and terrain traps.

Avalanche Summary

A few small natural and human-triggered loose dry avalanches were reported in steep northeast facing terrain. See this great MIN for details!

We expect unconsolidated snow will remain reactive to skier traffic on Tuesday in steep terrain. Carefully manage sluffing and minimize exposure to overhead hazards wherever possible.

Snowpack Summary

20 to 35 cm of storm snow blankets the area. Expect to find deeper deposits on north and east slopes in wind-loaded areas. Storm snow has not bonded well to the old snow surfaces, which includes melt-freeze crusts on sun-exposed slopes, large surface hoar or facets on shaded slopes, and wind-affected snow in exposed terrain at ridgelines.

The lower snowpack is strong and bonded. Treeline snow depths average 150 to 200 cm.

Weather Summary

Monday Night

Partly cloudy. 5 to 15 km/h east ridgetop wind. Treeline temperature -14 °C.

Tuesday

Mainly cloudy with a chance of flurries, 1 to 2 cm of snow. 5 to 15 km/h east ridgetop wind. Treeline temperature -12 °C.

Wednesday

A mix of sun and cloud. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -11 °C.

Thursday

Clear. 10 km/h northeast ridgetop wind. Treeline temperature -9 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
