Regions

Rossland, South Okanagan, Shuswap, North Okanagan.

Weak layers in the upper snowpack are buried at a depth where human-triggering is possible.

Watch for signs of instability like shooting cracks and back off steep slopes if observed.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

In the past week, reported avalanche activity has been small size 1 dry loose and storm slabs.

Snowpack Summary

Roughly 15 to 25 cm of recently accumulated snow has buried a widespread layer of surface hoar/facets and a crust.

Below this, the upper snowpack has several crusts and/or surface hoar layers depending on aspect and elevation. Isolated pockets of preserved surface hoar have been triggered in the past week.

The remainder of the snowpack is dense and well bonded, containing many more crusts.

Weather Summary

Wednesday Night
Partly cloudy. 1 to 3 cm of snow. 10 km/h west ridgetop wind. Treeline temperature -15 °C.

Thursday
Mix of sun and clouds. 2 cm of snow. 10 km/h northwest ridgetop wind. Treeline temperature -15 °C.

Friday
Mostly sunny. 10 km/h southwest ridgetop wind. Treeline temperature -13 °C.

Saturday
Mostly sunny. 40 km/h south ridgetop wind. Treeline temperature -9 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.

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.
