Regions

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

Choose low-consequence terrain

The combination of 40 to 90 cm of storm snow, strong wind, and weak layers means rider triggered avalanches are very likely.

Confidence

Moderate

  • Uncertainty is due to how quickly the snowpack will recover and gain strength.

Avalanche Summary

Over the past couple days numerous storm slab avalanches up to size 2.5 have been observed in the region. These avalanches were triggered naturally, remotely, and by riders on all aspects and elevations.

Snowpack Summary

By Thursday afternoon, 40 to 90 cm of storm snow may have accumulated with the highest amounts on the immediate coast. This new snow overlies surface hoar in sheltered features and wind pressed snow in exposed terrain. Below 1100 m this recent snow overlies a crust.

The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 250 cm to 350 cm.

Check out this MIN report from the Shames area for more details.

Friday

Cloudy. 15 to 35 cm of snow. 50 to 80 km/h south ridgetop wind. Treeline temperature -2 °C.

Saturday

Mostly cloudy. 25 to 45 cm of snow at treeline, rain below. 50 to 80 km/h south ridgetop wind. Treeline temperature 0 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be especially cautious as you transition into wind-affected terrain.
  • Use ridges or ribs to avoid areas of wind-loaded snow.

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.
