    Colder weather will add a little more stability to the snowpack. It is still too early to move out onto big alpine lines.

Weather Forecast

Freezing temperatures forecast for Saturday and Sunday may dip as low as double digits. 5 cm of accompanying light snow is expected.

Snowpack Summary

Deep instabilities may still be triggered in specific areas. Watch for thinner areas that may trigger depths over one metre. While rotten basal layers are not universal, they can still be found on different aspects. A change in wind direction to a more northerly flow may create small windslabs in the alpine.

Avalanche Summary

Small high altitude sloughing in lee areas and small solar releases in exposed aspects were noted.

Confidence

Freezing levels are uncertain
