Regions

Microwave-Sinclair, North Bulkley, South Bulkley, Telkwa.

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.
  • We are uncertain due to a highly variable snowpack.

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 overlies 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.

Below this, a layer of facets from early February and a thick crust from late January are at a similar depth between 70 and 110 cm. These layers remain possible to trigger with large loads and are most likely to be found on north-facing slopes.

Weather Summary

Saturday Night

Partly cloudy. 1 to 2 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -9 °C.

Sunday

Cloudy. 3 to 10 cm of snow. 30 to 60 km/h south ridgetop wind. Treeline temperature -9 °C.

Monday

Mostly cloudy. 4 to 20 mm of precipitation as snow or rain at treeline. 60 to 110 km/h southwest ridgetop wind. Treeline temperature 0 °C.

Tuesday

Mostly cloudy. 1 to 15 cm of snow. 50 to 90 km/h southwest ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.

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.
