Regions

Kootenay Boundary, Lizard-Flathead, Bonnington, Kootenay Pass, Akamina, Flathead, Lizard, Moyie.

A surface crust will create challenging travel conditions.

If dry snow exists in the alpine, watch for pockets of wind slab in lee terrain features.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast

Avalanche Summary

A crust has formed on the surface making avalanche activity unlikely. If dry snow exists in alpine terrain, human-triggered wind slabs are possible.

A natural avalanche cycle occurred at the beginning of the week, many avalanches (size 1-2) occurred on all aspects and elevations.

Snowpack Summary

A crust or moist snow exists on the surface at most elevations due to recent rain and warm temperatures. Below this, the upper snowpack has various depths of moist or wet snow from recent rain.

There are multiple crusts in the mid and lower snowpack, and it is generally dense and well-settled.

The average snowpack depth at treeline is roughly 150 to 200 cm.

Weather Summary

Thursday Night
Clear skies. 20 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Friday
Sunny. 20 km/h west ridgetop wind. Treeline temperature -6 °C.

Saturday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1900 m. Above freezing layer (AFL) in the alpine.

Sunday
Mostly sunny. 20 km/h northwest ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Watch for areas of hard wind slab on alpine features.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
