Regions

Kispiox, Ningunsaw.

Be especially cautious in steep, wind-affected terrain where triggering slabs is most likely.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Reports of avalanche activity have tapered; no new avalanches have been reported this week.

Snowpack Summary

Up to 10 cm of new snow covers surface hoar. This overlies 15 to 20 cm of faceting snow from recent cold temperatures. This snow was redistributed by moderate southwest wind and overlies previously wind-affected surfaces, treeline and above, and at lower elevations, a crust.

Two weak layers remain a concern:

  • A crust/facet layer buried early February down 90 to 120 cm.

  • A surface hoar layer buried mid-February down 60 to 90 cm.

Recent avalanche activity has involved these layers, with natural and human-triggered avalanches reported.

Below these layers, the remaining snowpack is generally well settled.

Weather Summary

Friday Night

Partly cloudy. 1 to 8 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -12 °C.

Saturday

Mostly cloudy. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -12 °C.

Sunday

Mostly cloudy. 4 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Monday

Mostly cloudy. 10 to 35 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
  • Watch for areas of hard wind slab on alpine features.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

Problems

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.

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.
