Points saillants

Start your day early and watch the crust closely.

As it breaks down, reduce your exposure to avalanche terrain.

    Wet loose avalanches will become more likely as the sun and warmth affect the snowpack. Start early, and avoid the hottest part of the day.

Avalanche Summary

On Wednesday, a small wet loose avalanche (size 1.5) was reported near Fernie in the early afternoon.

No other avalanches have been observed since Monday. However, observations are very limited at this time of year.

Snowpack Summary

On northerly slopes in the alpine, there may still be around 20 cm of soft snow from earlier in the week, potentially wind affected in exposed spots. Everywhere else, it's likely there is a thick crust on the surface.

The mid/lower snowpack is well settled and strong.

Lower elevations are melting out rapidly.

Terrain and Travel Advice

  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avalanche danger will increase as the surface crust breaks down.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
