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, there were a few small wet loose avalanches from slopes facing the sun.

Observations are very limited at this time of year.

Snowpack Summary

A crust is likely on the surface everywhere except northerly aspects in the alpine where around 15 cm of recent soft snow may still be preserved.

While weak layers lower in the snowpack have been a concern throughout the season, the current lack of avalanche activity and benign weather suggest they are not a concern at this time. They could become problematic again this spring as the temperature rises.

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.
