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

Watch for small wind slabs developing on Sunday as winds increase. Early season conditions exist...but if the snow is deep enough to ride, it's deep enough to slide.

Confidence

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.

Snowpack Summary

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

Surface conditions are variable. A sun crust can be found on some 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

Saturday Night

Partly clear skies overnight with northwest winds around 30 km/hr. No snow is expected.

Sunday

Mostly sunny skies with no new snow, northwest winds increasing, 20-50km/hr. Treeline temperature -5 °C.

Monday

A mix of sun and cloud with no new snow expected, west ridge winds 10 to 30 km/h, treeline temperature -7 °C.

Tuesday

Clear skies with westerly winds. Temperatures drop to around -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.

Avalanche Problems

Wind Slabs

Wind slabs may be found at higher elevations, primarily in east facing terrain features (although wind direction has varied throughout the region). New wind slabs may form through the day on Sunday, as snow is available for transport.

Aspects: North, North East, East, South East, South, North West.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
