Regions

Northwest Inland.

A gradual improvement in avalanche danger is expected over the weekend.

Confidence

Poor - Due to the number of field observations

Weather Forecast

Expect a change to cooler conditions on Friday and through the weekend. Light snowfall is expected on Friday, tapering off on Saturday. Winds are expected to be light to moderate from the south-west to south-east.

Avalanche Summary

There are no new avalanche reports from the region. Please let us know what you're seeing out there. Submit your information under 'Avalanche Information' on the bulletin web page.

Snowpack Summary

Around 20cm of new snow sits on previously rain-soaked snow below treeline. At alpine elevations, this new snow may be adding to recent storm slabs and wind slabs. Deeper in the snowpack, weaknesses such as loose sugary facets and crusts exist at least in some locations. We have limited field observations. Check out the Bulkley Valley Ski Society Facebook page for recent observations from the Hankin and Evelyn areas.

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.
