Kootenay Boundary

Recent wind has varied in direction, so watch for wind slabs on all aspects.

Persistent slabs may remain possible to trigger at upper elevations.

Moderate

• We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

No new avalanches were reported on Monday.

Variable winds have redistributed 10 to 15 cm of recent snow.

The recent snow sits on a 1 to 10 cm thick crust. The thickness of the crust depends on elevation.

At upper elevations, where the crust is thinner or not present, it may still be possible to trigger persistent slabs on multiple buried weak layers of surface hoar and/or crusts in the top 120 cm of the snowpack.

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

Tuesday Night
Mostly cloudy. 0 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Wednesday
Mostly cloudy. 0 to 5 cm of snow, then another 15 to 25 cm overnight. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Thursday
Mostly cloudy. 0 to 5 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Friday
Mostly cloudy. 20 km/h west ridgetop wind. Treeline temperature -9 °C.

• Recent wind has varied in direction, so watch for wind slabs on all aspects.
• If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
• Be aware of the potential for large avalanches due to buried surface hoar.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
