Regions

Northwest Coastal, Northwest Inland, Boundary, Kitimat, Nass, Rupert, Seven Sisters, Shames, Stewart, Howson, Kispiox, Ningunsaw.

Avalanche danger will increase through the day as storm snow piles up.

It's a good day to choose smaller slopes. Be ready to retreat to mellow terrain if you start seeing signs of instability.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.
  • We are uncertain due to the track and intensity of the incoming weather system.

Avalanche Summary

While details are lacking, a size 3 persistent slab avalanche was remotely triggered on a north-facing alpine slope on Friday. It appeared to occur on a steep, rocky slope with a thin-to-thick snowpack.

On Sunday, north of Stewart, two wind slab avalanches were reported in the alpine. One size 1 vehicle triggered, and one size 2.5 natural.

Wet loose avalanches continue with warm temperatures and strong sun. With cooler, cloudy conditions this trend is expected to taper.

Snowpack Summary

Expect 25-50 cm of storm snow to have accumulated by the end of the day on Tuesday. This covers crusty surfaces across most terrain, except in high alpine north-facing areas, where dry, wintry snow can still be found.

On solar aspects and lower elevations, surface crusts are less robust and possibly breakable and/or moist snow.

Several persistent weak layers are buried up to 250 cm deep. While triggering these layers is becoming unlikely, they present a low-probability, high-consequence problem. A cornice fall (large load) may be enough to trigger this slab.

Weather Summary

Monday Night

Cloudy. 10 to 15 cm of snow, possibly 25 cm or more near Prince Rupert and Kitimat. 30-50 km/h south ridgetop wind decreasing to 10 to 25 km/h by the morning. Treeline temperature -5 °C. Freezing level falling to 500 m.

Tuesday

Mostly cloudy. 3 to 10 cm of snow, with possible hotspots of 20 cm. 10-25 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level rising to 750 m.

Wednesday

Mix of sun and clouds. 2 to 5 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -4 °C.

Thursday

Mix of sun and clouds. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be aware of the potential for large, destructive avalanches due to deeply buried weak layers.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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.
