Regions

Kispiox, Ningunsaw.

We continue to track a weak layer in the snowpack.

Avoid thin snowpack areas where this may be easier to trigger.

Confidence

Moderate

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

Avalanche Summary

January 20

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

January 19

  • Few small wind slabs were reported in steep north-facing alpine terrain that appeared to have been triggered by cornice fall.

January 18

  • Large (up to size 2.5) explosive controlled avalanches were reported on southwest aspects in the alpine and treeline, failing on buried surface hoar.

Snowpack Summary

A crust exists on or near the surface in almost all terrain from the prolonged heat, rain and inversion.

The upper 80 to 150 cm of snow has been altered by previous strong southerly winds at upper elevations. The top 10 cm of the most recent crust is facetting in alpine and at treeline. Below 1000 m expect surface hoar on this crust in sheltered areas.

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

Wednesday Night
Clear skies. 10 km/h northeast ridgetop wind. Treeline temperature -4 °C.

Thursday
Sunny. 10 km/h northeast ridgetop wind. Treeline temperature -6 °C.

Friday
Sunny. 20 km/h east ridgetop wind. Treeline temperature -8 °C.

Saturday
Sunny. 20 km/h southwest ridgetop wind. Treeline temperature -5 °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

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.
