Regions

Northwest Coastal, Boundary, Stewart, Ningunsaw.

Avalanche danger will increase throughout the day with strong winds and heavy snowfall in some areas. Adjust your terrain choices accordingly.

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

A few wind or storm slab avalanches (up to size 2) have been reported since the weekend, along with several loose dry avalanches (up to size 1) in very steep terrain.

Recent observations have been limited due to cloudy or foggy conditions, especially at higher elevations.

Snowpack Summary

Roughly 20 to 40 cm of recent snow has accumulated this week, with up to another 40 cm possible by Thursday afternoon.

At treeline and above, the recent storm snow has buried either a crust of variable thickness or firm, settled snow. Below treeline, the new snow rests atop a thin crust, with the underlying snow remaining largely moist or isothermal.

A crust, with possible surface hoar or faceted snow above or below it, was buried on January 26 and is now roughly 80 to 150 cm deep. This layer is most likely to persist at higher elevations, while at lower elevations, it was likely rain-soaked and destroyed last week.

Snow depths at treeline across the region range from 250 to 450 cm.

Weather Summary

Wednesday Night
Cloudy. 10 to 20 cm of snow. 60 km/h south ridgetop wind. Treeline temperature -3 °C.

Thursday
Cloudy. 15 to 30 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Friday
Mix of sun and clouds. 2 to 5 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -6 °C.

Saturday
Mostly sunny. 30 km/h northwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Watch for fresh storm slabs building throughout the day.
  • Be careful as you transition into wind-affected terrain.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
