Regions

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

While spring-like weather has arrived, the snowpack continues to adjust and stabilize. Large persistent slab avalanches remain possible, particularly on steep northerly alpine slopes.

Confidence

Moderate

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

Avalanche Summary

A few large (up to size 3) natural persistent slab avalanches have occurred in recent days. One size 3 may have been remotely triggered. These large avalanches have occurred on northwest through east-facing slopes in the alpine.

Snowpack Summary

A strong, supportive crust is expected on the surface on all aspects at treeline and on all but north-facing terrain in the alpine. Below treeline, a full overnight refreeze may not occur, resulting in moist snow or a thin, weak, breakable crust. Wind-affected surfaces are likely in north-facing alpine terrain.

Surface crusts are expected to soften and weaken through the day with warming temperatures and solar input.

A thick crust with weak faceted snow is buried roughly 100 to 200 cm deep and continues to produce large, surprising avalanches.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Be careful as you transition into wind-affected terrain.

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.

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.
