Regions

Northwest Inland, Kispiox, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

Recent snow rests on a weak layer, and likely remains reactive to riders. Don't let good riding lure you into complacency.

Confidence

Moderate

Avalanche Summary

Observations have been limited. There have been no recent reports of avalanches in the region.

If you are getting out in the backcountry, consider sharing your observations on the Mountain Information Network (MIN)!

Snowpack Summary

50 to 70 cm of snow fell earlier this week. At upper elevations, wind has loaded deep deposits into leeward terrain. In wind-sheltered areas, the recent snow sits over a weak layer of feathery surface hoar crystals, making for a poor bond.

The mid snowpack contains a crust with small facets above it, but does not present a problem at this time.

The snowpack is around 1 m deep at treeline, tapering quickly with elevation.

Weather Summary

Thursday night
Partly cloudy. 20 km/h west ridgetop wind. Treeline temperature -10 °C.

Friday
Partly cloudy. 20 km/h northwest ridgetop wind. Treeline temperature -12 °C.

Saturday
Cloudy. 10 cm of snow. 50 to 80 km/h southwest wind at all elevations. Treeline temperature -8 °C.

Sunday
Mostly cloudy. 10 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Choose simple, low-angle terrain without steep convex rolls.

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.
