Regions

Kispiox, Ningunsaw.

It's still warm at higher elevations, so be cautious of overhead hazards and large terrain.

It is uncertain how the continued warmth will affect the snowpack so watch for signs of instability

Confidence

Moderate

  • Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.

Avalanche Summary

January 17

  • No new avalanches reported but observations are limited. Consider posting to the MIN if you are out in the mountains!

January 16

  • A large (size 2) natural cornice triggered avalanche was reported on a northwest aspect.

January 14

  • A natural avalanche cycle was reported, with small (size 1) wet avalanches at lower elevations and large (up to size 2.5) wind or persistent slab avalanches in the treeline and alpine.

Snowpack Summary

80 to 150 cm of snow fell early last week accompanied by strong southerly winds at upper elevations and has settled from warm temperatures at all elevations.

In sheltered ares at lower elevations this snow is possibly resting on surface hoar.

On steep south aspect slopes a surface crust is present in the alpine.

At treeline and below, 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.

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.

Tuesday
Sunny. 10 km/h east ridgetop wind. Treeline temperature -1 °C with an above freezing layer between 1500 m and 2600 m.

Wednesday
Mostly sunny. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C. with an above freezing layer between 2000 m and 2300 m.

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.
