Clearwater, South Okanagan, Shuswap, North Okanagan.

Watch for slabs in lee areas.

Investigate the bond to the old snow before entering steep terrain.

Confidence

Moderate

Avalanche Summary

We haven't received any reports of recent avalanche activity.

Please consider posting a MIN if you head into the backcountry.

Snowpack Summary

Another 5 to 10 cm of snow is expected to fall with strong wind on Thursday. Potentially building storm slabs in lee areas.

Around 30 to 60 cm of snow may overlie surface hoar and/or faceted grains and a hard melt-freeze crust from mid-November. Weak faceted grains may extend to the base of the snowpack, particularly in areas where the snowpack is thin.

Snow depths at treeline vary from about 50 to 100 cm and decrease rapidly at lower elevations.

Weather Summary

Wednesday Night
Cloudy. Around 5 cm of snow at treeline, falling as rain below. 50 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 1700 m.

Thursday
Mostly cloudy. 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -5 °C. Freezing level 1300 m.

Friday
Mostly cloudy. 5 to 10 cm of snow. 30 to 50 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1200 m.

Saturday
Mostly cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 2100 m.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Be careful as you transition into wind-affected terrain.
  • Be cautious of buried obstacles, especially below treeline.

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.
