Low old and moderate wet snow problem

Low old and moderate wet snow problem

The avalanche risk is moderate. A few small, wet avalanches can occur spontaneously or be triggered by a winter sports enthusiast, and medium avalanches are still possible in isolated cases. Individual gliding avalanches are also possible. There is also a minor persistent weak layer problem from around 1600 metres where the old snowpack has survived. Avalanches usually remain small, but can be triggered by individuals.

The snowpack is moist to wet and well settled up to high altitudes. Where there was an old snowpack before the snowfall, it still contains weak layers of large faceted crystals, especially near the ground.

The night will start clear at first, but clouds will increase from the west. In the second half of the night there may be light showers, from around 1800 m as snow. On Sunday, the sky will often be overcast and short showers may fall, from around 1700 metres as snow. The wind will remain weak. At 2000 m around -1 degrees.

Avalanche danger is slowly decreasing as the snow melts. However, outgoing longwave radiation will be limited on Monday night.
