Regions

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

Stick to conservative, low-angle slopes with no overhead hazard.

Human and naturally triggered avalanches are likely and could occur at all elevations.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

We expect a natural avalanche cycle occurred on Wednesday but at the time of publishing we have yet to receive reports.

Numerous 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 west, north, and east facing slopes.

Snowpack Summary

By Thursday morning, storm totals are expected to reach 50 to 80 cm in most areas, up to 100 cm may have fallen on the immediate coast. This new snow was accompanied by strong to extreme southwest wind, forming deeper deposits on north and east facing terrain. In sheltered terrain this new snow could overlie surface hoar or a sun crust.

Several layers of crust, surface hoar or facets are buried in the top meter of the snowpack. These layers are most concerning on sheltered treeline features.

Below, the remaining snowpack is generally well settled and well bonded.

Weather Summary

Wednesday Night
Mostly cloudy. 10 to 15 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Thursday
Mostly cloudy. 3 to 5 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Friday
Mix of sun and clouds. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Saturday
Mostly cloudy. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Keep your guard up at lower elevations. Storms slabs have been reactive at all elevations.

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.
