Lo esencial

Avalanche conditions are becoming quite manageable with normal cautions. Watch for areas of reactive wind-loaded snow and keep up those safe travel practices.

    10 to 20 cm of recent snow and moderate southwest winds formed wind slabs at upper elevations. These slabs are most likely to still be reactive on steep, leeward features immediately below ridgetop.

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

It's been an increasingly quiet couple of days in the Kootenay Boundary. No new avalanches were reported on Friday.

On Thursday, several natural and skier triggered wind slabs up to size 1.5 were reported on north/east aspects in the alpine. Natural wet loose avalanches up to size 2 were also reported on steep solar aspects.

If you are heading into the backcountry, please consider sharing conditions by posting a MIN.

Snowpack Summary

Surface crust has likely begun to form on solar aspects, topping 10 to 25 cm of recent snow, which was affected by moderate southwest winds, forming wind slabs on lee aspects at upper elevations. These may still be reactive on steep slopes below ridgetop.

The recent snow sits on a crust from early March that is 5 to 20 cm thick in most locations. It may become thinner at upper elevations.

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

Weather Summary

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
