Kootenay Boundary

Investigate the bond of the recent snow before committing to your line.

On Monday, a skier triggered size 1 storm slab was reported on north aspect in the alpine.

If you're heading into the backcountry, please share what you see on the Mountain Information Network: How much new snow was up high? Was it wet or dry? Did you see avalanches?

Up to 15 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects at upper elevations.

A typical spring diurnal pattern is in effect: daytime warming moistens the upper snowpack, while overnight cooling usually forms a hard crust at higher elevations.

Lower elevations may not refreeze and are melting out quickly.

• Investigate the bond of the recent snow before committing to your line.
• Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
