Regions

Northwest Coastal, Boundary, Stewart, Kispiox, Ningunsaw.

Wind slabs remain a concern, shifting winds may form fresh, reactive slabs.

Buried weak layers exist inland; avoid large, open slopes capable of producing big avalanches.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Wind slabs continue to be sensitive to rider triggers, primarily at treeline elevations on north/west aspects.

A remotely triggered size 2.5 persistent slab was reported on a west aspect at treeline, failing on buried weak layers.

Meanwhile cold temperatures mean dry loose avalanches are becoming more common in very sheltered, steep terrain.

Snowpack Summary

Outflow winds have sculpted the snowpack. Most exposed terrain is sastrugi or has been scoured down to old crusts. On sheltered slopes, wind slabs persist.

20 to 60 cm of snow overlies facet, crust and/or surface hoar layers in isolated wind-sheltered terrain features (primarily at treeline and below). Reports suggest this may be a concern in inland areas.

A January crust with associated facets is buried 100 to 200 cm deep. Below, the remaining snowpack is generally well settled and well bonded.

Weather Summary

Monday Night
Partly cloudy. 1 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mostly cloudy. 3 to 5 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -8 °C.

Wednesday
Mostly cloudy. 10 to 20 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Thursday
Mix of sun and clouds. 4 to 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Use careful route-finding and stick to moderate angled slopes with low consequences.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
