Regions

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

Recent snow has accumulated atop a widespread crust.

Check the bond between new snow and the crust before committing to avalanche terrain.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

A few small avalanches (size 1 and 10 to 20 cm deep), both slab and loose dry, were reported on Sunday. With continued snowfall through Monday and Monday night, slab avalanches are expected to become more likely and increase in size.

Snowpack Summary

Roughly 10 to 30 cm of recent snow has accumulated, accompanied by moderate southwest winds.

At treeline and above, the recent snow rests on a crust of variable thickness and strength. Below treeline, the upper snowpack remains largely moist or isothermal.

A widespread crust, with possible surface hoar or faceted snow either above or below it, was buried on January 26 and is now up to 100 cm deep.

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

Weather Summary

Monday Night
Mostly cloudy. 2 to 10 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Tuesday
Mostly cloudy. 1 to 5 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -3 °C.

Wednesday
Mostly cloudy. 4 to 10 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 800 m.

Thursday
Mostly cloudy. 10 to 20 cm of snow. 70 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be careful as you transition into wind-affected terrain.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.

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.
