Kootenay Boundary

The recent snow may require more time to stabilize and bond to underlying surfaces before venturing into bigger terrain.

A mix of natural, skier-triggered, and explosive-triggered storm or wind slab avalanches have been reported over the last 4 days. Avalanches were sized 1 to 2, generally all in the upper 40 cm of snow and on various aspects and elevations.

This MIN report describes a size 1 avalanche at treeline that is fairly consistent with other reports.

The upper snowpack continues to settle and bond. Moist snow surfaces exist below treeline.

Below the recent snow accumulations, down roughly 30 to 50 cm, is a layer of old wind-affected surfaces and weak faceted grains.

Currently, the mid and lower snowpack is generally well-bonded, featuring a thick crust near its base.

Tuesday Night

Cloudy with trace snow amounts, southwest alpine winds 10 to 20 km/h, treeline temperature -4 °C.

Wednesday

Cloudy with 0 to 8 cm of snow, southwest winds 20 to 30 km/h, treeline temperature -5 °C.

Thursday

Cloudy with trace snow amounts, southwest alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Friday

Cloudy with trace snow amounts, southwest alpine winds 10 to 30 km/h, treeline temperature -6 °C.

• Closely monitor how the new snow is bonding to the old surface.
• Be carefull around freshly wind loaded features.
• Avoid steep convex slopes.
