Regions

Kootenay Boundary.

The latest storm to impact the interior is predicted to produce light to moderate amounts of precipitation. A conservative approach to terrain selection continues to be the best way to manage a persistent slab problem. Click here for more info.

Avalanche Summary

No new avalanches have been reported in past few days.

Snowpack Summary

Around 10 to 15 cm of snow sits on a thin sun crust on southerly aspects and small feathery surface hoar in sheltered areas.Beneath this, around 50 to 100 cm of snow is poorly bonded to a rain crust and a weak layer of feathery surface hoar and sugary facets. Although there has not been a reported avalanche on this layer for about a week, snowpack test results tell us that it is still possible to trigger. It is best to remain conservative and travel cautiously with this layer in the snowpack.The lower snowpack is well-settled.

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.
