Regions

Nass, Seven Sisters, Kispiox, Ningunsaw.

Track new snow amounts and reactivity as you investigate the storm outcome on Wednesday. Wind loaded areas will likely be the first to reveal how new snow is bonding.

Confidence

High

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

A skier triggered a 10 to 35 cm-deep size 1.5 windslab on a steep, NE-facing feature in the Babines on Monday, the first indication of an expected uptick in avalanche conditions with ongoing snowfall and wind.

On January 21 there was an isolated report of a skier triggering a persistent slab avalanche when transitioning into wind affected terrain. A firm wind slab stepped down 70 cm to the early January weak layer below. Concern for this layer has been steadily diminishing.

Snowpack Summary

Less than 10 cm of new snow should accumulate by end-of-day Wednesday under strong to extreme winds, bringing new snow totals to around 15 - 20 cm. The new snow has buried heavily wind-affected and crusty surfaces almost everywhere.

In shelter below 1000 m there is large surface hoar on this crust that will promote reactivity once there's enough snow for a slab.

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

Tuesday Night
Cloudy with flurries bringing up to about 5 cm of new snow. 40 to 50 km/h south ridgetop wind, easing. Treeline temperature -3 °C.

Wednesday
Staying mostly cloudy with a precip break before afternoon flurries bring 1 to 3 cm of snow, continuing overnight. 40 to 50 km/h southeast ridgetop wind, increasing. Treeline temperature -2 °C with freezing level rising to 1100 m.

Thursday
Mostly cloudy with diminishing flurries bringing 5 to 10 cm of new snow, including overnight. 50 km/h south ridgetop wind. Treeline temperature -1 °C with freezing level reaching 1200 m.

Friday
Mostly cloudy with flurries continuing from overnight bringing 10 to 25 total cm of new snow. 40 to 60 km/h south ridgetop wind, increasing. Treeline temperature -1 °C. Freezing level to 1200 m.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Make observations and continually assess conditions as you travel.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.

Problems

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.
