Regions

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

Stick to conservative terrain free from overhead hazard, as storm snow and wind build reactive slabs

If you see greater than 30 cm of snow, treat danger as HIGH - natural avalanches are likely

Confidence

Moderate

  • Forecast precipitation (either snow or rain) amounts are uncertain.
  • Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Avalanche Summary

We expect natural and human triggered avalanches to be likely as storm snow accumulates.

Snowpack Summary

By 4 p.m. Monday, up to 30 cm of new snow is possible in coastal terrain, decreasing to around 20 cm near Shames and 10 cm further inland. The new snow will fall on a mix of weak surface hoar and facets, as well as hard wind affected surfaces. At lower elevations, the new snow will fall on 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.

Weather Summary

Sunday Night
Mostly clear skies. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -12 °C.

Monday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mostly cloudy. 15 to 20 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mostly cloudy. 5 to 15 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -6 °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.
  • Don't let storm day fever lure you into consequential terrain.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.

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.
