Lo esencial

Give cornices a wide margin when travelling beneath them and when on ridgelines. Avalanches are unlikely where there is a thick surface crust.

    Cornices along ridgelines are very large and looming. They weaken with progressive warming and could fail at any time.

Moderate

Avalanche Summary

We haven't received any recent reports of avalanches.

If you head to the backcountry this weekend, please consider submitting a MIN report.

Snowpack Summary

Around 10 cm of snow from the weekend may remain dry and soft on northerly alpine slopes. Elsewhere, a hard and thick melt-freeze crust prevails. The crust may soften with daytime warming and re-freeze overnight.

There are no layers of concern in the middle and lower snowpack.

The snowpack is rapidly melting at lower elevations.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
