Regions

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

Watch for recently formed and reactive storm slabs. Be especially cautious as you transition into wind-affected terrain.

Confidence

Low

Avalanche Summary

Our limited field data suggests a natural avalanche cycle occurred in the past few days as rain and warm temperatures infiltrated the region.

Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

New snow accumulates atop a crust or moist snow from rain in the past few days. Strong winds will redistribute new snow and create heavily wind-affected surfaces.

The remainder of the snowpack is strong, with various hard layers and crusts.

Weather Summary

Friday Night

Cloudy with 1 to 8 mm of precipitation. 15 to 40 km/h southwest ridgetop wind. Treeline temperature drops to -1 °C.

Saturday

Cloudy with 5 to 15 cm of snow. 15 to 40 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Sunday

Mostly cloudy with isolated flurries. 15 to 30 km/h northwest ridgetop wind. Treeline temperature -3 °C.

Monday

Cloudy with light flurries. 15 to 30 km/h west ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.

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.
