Kootenay Boundary

A weak layer will continue to linger over the holiday season. A conservative approach to your terrain selection is the best way to manage it. See the forecaster's blog here, which describes this persistent problem.

WEDNESDAY NIGHT: Cloudy with light snowfall, freezing level below valley bottom.THURSDAY: Mix of sun and cloud, light northwest winds, alpine temperature -10 C, freezing level below valley bottom.FRIDAY: Increasing clouds over the day, light to moderate west winds, alpine temperature -12 C, freezing level below valley bottom.SATURDAY: Cloudy with snowfall, accumulation 5 to 10 cm, strong southwest winds, alpine temperature -5 C, freezing level rising to 900 m over the day.

One small wind slab avalanche was triggered by explosives with a depth of about 15 cm. Otherwise no new avalanches were observed on Tuesday.

Around 5 cm of snow fell on Wednesday. This fell 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.
