Regions

Microwave-Sinclair, North Bulkley, South Bulkley, Telkwa.

A significant amount of new snow and rain are causing dangerous avalanche conditions.

Reduce your exposure to overhead hazard and stay away from run-out zones.

Confidence

Moderate

  • Persistent slabs could become more likely with the forecast weather.
  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

No new avalanches have been reported in the past few days.

If you head out in the backcountry, let us know what you're seeing by submitting a MIN report.

Snowpack Summary

Up to 60 cm of new snow will have fallen above 1400 m by Tuesday morning, accompanied by strong southerly winds. This new snow is falling on surface hoar and faceted snow from recent cold temperatures.

Below this, a layer of facets from early February and a thick crust from late January are at a similar depth between 80 and 120 cm below the snow surface. These layers remain possible to trigger with large loads and are most likely to be found on north-facing slopes.

Weather Summary

Monday Night
Cloudy. 15 to 20 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m.

Tuesday
Mostly cloudy. 3 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1100 m.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Thursday
Mostly sunny. 1 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Carefully manage your exposure to overhead hazards.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

Problems

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.

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.
