Kootenay Boundary, Bonnington, Grohman, Kootenay Pass, Norns, Rossland, South Okanagan, Ymir, Shuswap.

Early season hazards are the main concern in this shallow snowpack. It's a great time to brush up on your rescue skills, check your gear, and do some snow dances!

Moderate

Avalanche Summary

No new avalanches have been reported in the past few days.

Observations are limited this time of year. Please consider filling out a MIN report if you do head out in the backcountry! 🙏

Snowpack Summary

Expect early-season conditions with a shallower-than-average snowpack. At treeline, snowpack depths are between 30-80 cm. Below treeline, snowpack depths taper off quickly.

Surface conditions are variable. Surface hoar growth has been reported in many areas. A sun crust can be found on steep south and west-facing slopes, and wind effect exists on exposed terrain at treeline and above.

A crust with facets or depth hoar exists at or near the ground.

Weather Summary

Monday night

Cloudy with clear periods, no precipitation, southwest alpine wind 5 to 15 km/h, treeline temperature -6 °C.

Tuesday

Sunny with cloudy periods, no precipitation, southwest alpine wind 5 to 15 km/h, treeline temperature -5 °C.

Wednesday

Sunny with cloudy periods, no precipitation, northwest alpine wind 5 to 15 km/h, treeline temperature -7 °C.

Thursday

A mix of sun and cloud, no precipitation, south alpine wind 5 to 10 km/h, treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

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.
