Regions

Northwest Coastal, Boundary, Stewart, Ningunsaw.

Recent storm snow needs time to settle and gain strength. Human-triggered avalanches remain possible.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Several size 1 to 2.5 explosive-triggered avalanches occurred Wednesday night, with an average depth of about 30 cm.

An avalanche cycle likely occurred Wednesday night into Thursday during periods of rapid loading from heavy snowfall and strong winds. While unlikely, very large avalanches may have occurred if storm slabs stepped down to the January 26 weak layer.

Natural avalanche activity is expected to decrease significantly on Friday as stormy conditions end.

Snowpack Summary

Approximately 50 to 70 cm of storm snow has accumulated since early this week, with strong southerly winds redistributing snow throughout the storm.

At treeline and above, recent storm snow overlies either a crust of variable thickness or firm, settled snow. Below treeline, new snow sits on a thin crust, with moist or isothermal snow beneath.

A January 26 crust, with possible surface hoar or faceted snow above or below it, is now buried 100 cm or deeper and is likely limited to higher elevations. At lower elevations, it has likely been rain-soaked and destroyed.

The remainder of the mid and lower snowpack is generally well settled with no significant concerns.

Weather Summary

Thursday Night
Mostly cloudy. Trace amounts of snow. Southwest ridgetop wind decreasing from 70 to 30 km/h overnight. Treeline temperature -5 °C.

Friday
Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -6 °C.

Saturday
Mostly sunny. 20 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Sunday
Mostly cloudy. Trace amounts of snow. 40 km/h west ridgetop wind. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid freshly wind-loaded terrain features.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
