Regions

Little Yoho.

Until we receive more snow, ski touring is a disheartening prospect. However, many of the local ice climbs are coming into good shape.

Weather Forecast

Expect the current and relatively benign weather pattern to persist for the next 3 days. As such, little change is expected.

Snowpack Summary

Roughly 100cm of snowpack exists at treeline. The Oct 27th crust is still a prominent feature in the snowpack (approx. 15cm from ground) and producing variable results with snowpack tests.

Avalanche Summary

No avalanches were observed or reported today.

Confidence

The weather pattern is stable

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.
