Regions

North Columbia, South Columbia, Esplanade, Jordan, North Selkirk, West Purcell, Badshot-Battle, Central Selkirk, Goat, Gold, Retallack, Valhalla, Whatshan.

Continually monitor local conditions. The likelihood and size of avalanches will increase through the day on Friday as more snow is expected.

Confidence

Moderate

Avalanche Summary

A few size 1 wind slab and dry loose avalanches have been reported since last weekend, all in very steep terrain features.

Please consider posting a MIN if you are heading out in the backcountry!

Snowpack Summary

Recent snowfall amounts range from roughly 10 to 15 cm, with an additional 5 to 15 cm expected on Friday. Westerly winds will likely redistribute new snow into deeper deposits on leeward slopes at higher elevations.

In many areas, especially at treeline and below, the new snow now overlies a layer of surface hoar.

The mid snowpack contains a supportive melt-freeze crust, roughly 40 to 60 cm below the surface.

The average snow depth at treeline ranges from 70 to 120 cm and decreases dramatically at lower elevations.

Weather Summary

Thursday Night
Cloudy. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -6 °C. Freezing level 1000 m.

Friday
Cloudy. 5 to 15 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -6 °C. Freezing level 800 m.

Saturday
Cloudy. 15 to 30 cm of snow, with the highest amounts expected in the Monashee range. 20 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 700 m.

Sunday
Cloudy. 10 to 15 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 400 m.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be careful as you transition into wind-affected terrain.
  • Minimize exposure during periods of heavy loading from new snow and wind.
  • 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.
