Regions

Kispiox, Ningunsaw.

Increasing alpine temperatures and sunshine will make avalanche triggering possible on south aspect terrain.

Plan you day to avoid steep solar zones during daytime warming.

Confidence

Moderate

  • Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.
  • Uncertainty is due to the limited number of field observations.
  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary

Reports of avalanche activity has subsided as temperatures cooled.

On Wednesday, natural avalanches where reported, with wet avalanches at lower elevations and wind or persistent slabs to size 2.5 at higher elevations.

Past activity includes failures in recent storm snow as well as on deeper weak layers such as the early January surface hoar and the late December crust.

Snowpack Summary

Recent storm totals vary from 80-150 cm throughout the region, heavily redistributed by strong southerly winds at upper elevations and has likely settled from warm temperatures.

At treeline and below, recent rain and warm temperatures may have affected the surface snow. As temperatures cool this warm and wet snow has formed a stout melt freeze crust.

A layer of surface hoar is buried 40 to 70 cm deep in sheltered treeline features. The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 150 cm to 250 cm.

Weather Summary

Friday Night
Clear skies. 40 km/h west ridgetop wind. Treeline temperature 2 °C.

Sunday
Mostly sunny. 20 km/h west ridgetop wind. Treeline temperature 2 °C.

Monday
Mostly sunny. 30 km/h west ridgetop wind. Treeline temperature 2 °C.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Keep in mind that human triggering may persist as natural avalanches taper off.

Problems

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.

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.
