Regions

Kitimat, Rupert.

Expect variable conditions with snow, wind, and rain continuing.

Terrain that was sheltered from the wind and wasn't rained on should hold good riding and lower avalanche danger.

Confidence

Low

Avalanche Summary

We don't have any direct observations in this forecast area.

Looking forward to Wednesday, another dose of new snow and moderate to strong winds will make slab avalanches likely around treeline and above.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network). You can share riding conditions, avalanche or snowpack observations, or even just a photo or two.

Snowpack Summary

Up to 35 cm of recent snow and moderate to strong southwest and west wind may have formed reactive wind slabs on leeward slopes in the alpine. Depending on the exact freezing level, surface snow may be moist or soaked with rain at treeline and below.

A layer of weak, feathery crystals buried in mid November is 40 to 60 cm deep in sheltered treeline terrain.

Below 1400 m, a 2 to 10 cm rain crust sits 40 to 60 cm down.

Above treeline, the snowpack is roughly 200 cm, tapering steadily with elevation to around 30 cm at valley bottom, where many early-season hazards remain just below the surface.

Weather Summary

Tuesday Night
Cloudy. 2 to 5 mm of precipitation as snow or rain at treeline. 30 km/h southwest ridgetop wind. Average treeline temperature -1 °C. Freezing level 1100 m.

Wednesday
Cloudy. 15 to 20 mm of precipitation as snow or rain at treeline. 40-60 km/h southwest ridgetop wind. Average treeline temperature -1 °C. Freezing level 1000 m.

Thursday
Mostly cloudy. 5 mm of precipitation as snow or rain at treeline. 30 km/h southwest ridgetop wind. Average treeline temperature 1 °C. Freezing level 1500 m.

Friday
Mostly cloudy. 15 to 20 mm of precipitation as snow or rain at treeline. 30 km/h southwest ridgetop wind. Average treeline temperature 0 °C. Freezing level 1300 m.

Terrain and Travel Advice

  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Be cautious of buried obstacles, especially below treeline.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
