Kootenay Boundary

Assess for wind slabs along ridges and in alpine terrain.

A few small (size 1) dry loose avalanches were observed on Monday.

Most parts of the region received 5 to 10 cm of new snow on Tuesday, with up to 15 cm in parts of the Selkirks. A total of 15 to 30 cm of dry snow sits atop melt-freeze layers. Several crusts may be found in the top 50 cm of snowpack, depending on aspect and elevation.

The facet/crust layer that caused large avalanches in March is buried 100 to 180 cm deep and is unlikely to trigger under the current conditions.

• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
• Closely monitor how the new snow is bonding to the crust.
