Regions

Northwest Coastal, Boundary, Kitimat, Rupert, Shames, Stewart.

Avoid avalanche terrain as snow and wind are expected to build sensitive storm slabs.

Buried weak layers may become more reactive as load increases.

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain due to how buried persistent weak layers will react with the forecast weather.

Avalanche Summary

Size 1-1.5 rider triggered wind slabs have been reported in the last 3 days. Recent activity has mainly occurred at treeline elevations and on north or west facing slopes. As winds switch and storm snow accumulates, expect the larger and reactive slabs to be in north and east facing terrain.

A natural cycle is expected to occur in higher elevation, wind affected terrain.

Snowpack Summary

By Wednesday afternoon, storm totals are expected to reach 20-50 cm in most areas with up to 80 cm possible for immediate coastal terrain. New snow falls over heavily wind-affected surfaces of hard snow and old crusts.

Crust, facet and spotty surface hoar layers exist in the upper metre of the snowpack. These are most concerning at treeline and below, especially in shallow snowpack features.

A January crust and facet layer is buried 60 to 120 cm deep. Below, the remaining snowpack is generally well settled and well bonded.

Weather Summary

Tuesday Night
Cloudy. 5 to 20 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Wednesday
Mostly cloudy. 5 to 25 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Thursday
Mostly cloudy. 15 to 25 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Friday
Mix of sun and clouds. 2 to 4 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be aware of the potential for large avalanches due to buried weak layers.

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.
