Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Warm temps, sun, and persistent weak layers are creating tricky conditions

Choose conservative low-angle terrain with no overhead hazard.

Check out this forecaster blog on conditions.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

On Sunday, A natural cycle up to size 3 was observed on solar aspects with strong sun.

In the past few days, numerous skier-triggered persistent slab avalanches have occurred up to size 2. The majority of these avalanches happened on north through east aspects. Notably, these slabs have mostly occurred at treeline and below, and on lower-angle slopes.

A fatal, human-triggered (size 3.5) wind slab was triggered on Tuesday. MIN post here

Snowpack Summary

Strong to extreme southerly winds have created widespread wind effect and built wind slabs on lee slopes.

A melt-freeze crust can be found on sunny slopes and at lower elevations. This surface crust will likely soften with sun and daytime warming.

A couple of persistent weak layers buried in the last week may exist in the upper 30 to 60 cm of the snowpack. These consist of surface hoar, facets and crusts.

Buried around 60 to 100 cm is a prominent, persistent weak layer of facets and crust from early February.

The remaining snowpack appears to be strong and well-bonded.

Weather Summary

Monday

Sunny. 20 to 50 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 2000 m.

Tuesday

Mostly cloudy. 4 to 10 cm of snow. 30 to 70 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m.

Wednesday

Mix of sun and clouds. 1 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
