Regions

Kootenay Boundary, Purcells, Bonnington, Grohman, Kootenay Pass, Norns, Rossland, Ymir, Crawford, Moyie, St. Mary, Kokanee, Retallack, Valhalla.

Assess conditions as you travel.

Small wind slabs may exist at the highest elevations, while steep south-facing slopes could produce small wet loose avalanches under afternoon sun.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

The previous rain and warm temperatures produced a widespread wet avalanche cycle to size 3.5. Several persistent slabs also occurred naturally with impressive propagation. Some features have run full path, reaching the valley bottom.

If you are heading into the backcountry, please consider sharing conditions via the MIN.

Snowpack Summary

A widespread, developing melt-freeze crust exists to mountain top.

Below this, 30 to 50 cm of wet snow sits above a crust (1 to 10 cm thick), buried in early March. Various persistent weak layers may still exist in the top 120 cm of the snowpack - these layers may be a lingering concern at alpine elevations where a supportive surface crust does not exist.

The mid/lower snowpack is well settled and strong in most areas.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
