Regions

Kispiox, Ningunsaw.

Fresh, reactive wind slabs will form throughout the day.

Buried weak layers mean that triggering large avalanches is possible!

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been reported in the past few days.

If you head out in the backcountry, let us know what you're seeing by submitting a MIN report.

Snowpack Summary

Up to 15 cm of new snow covers surface hoar and facetted snow from recent cold temperatures. In open areas, strong southerly winds will be redistributing new snow, creating wind slabs and wind-affected surfaces. A crust can be found below this snow up to 1500 m.

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

Saturday Night

Partly cloudy. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -11 °C.

Sunday

Mostly cloudy. 1 to 5 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -12 °C.

Monday

Mostly cloudy. 15 to 30 cm of snow. 70 to 100 km/h south ridgetop wind. Treeline temperature -5 °C.

Tuesday

Mix of sun and clouds. 1 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -7 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • 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.

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.
