Low risk of small, wet avalanches

Low risk of small, wet avalanches

The avalanche risk is low. Individual small wet avalanches can spontaneously release from very steep terrain with the sun's rays. Terrain traps are less full due to a lack of snow and are therefore more effective.

Where there is still snow, the snowpack is moist to wet due to mild air and sunlight, depending on the altitudes, and closes with a melt-freeze crust, which forms a steep sunny slope during the day, but otherwise often remains hard and icy. The snow base, fundament is sometimes weakened by persistent weak layers.

The night will be clear for the time being, with widespread clouds moving through from midnight, which will frequently affect the sunshine on Friday. Mountains will remain partly clear. The wind will pick up during the day and blow moderately from mainly southerly directions. At 2000 metres, the temperature will be between -2 and 0 degrees.

No significant change in avalanche danger.
