Avalanche Activity

Fresh snow and drifts often prone to triggering, particularly on shady slopes

Avalanche danger above 1600m is moderate, below that altitude danger is low. Fresh snow and far-reaching snowdrift accumulations are easily triggered in all aspects in many places. Slabs can be triggered by minimum additional loading and grow to medium-to-large sized releases. Danger zones occur in wind-loaded steep terrain, behind sharp drops in the landscape, in gullies and bowls. The snowdrift accumulations generated over the last few days are blanketed by fresher snow, thus impossible to recognize. On very steep sunny grass-covered slopes, glide-snow avalanches can slide away, mostly of small size.

Snowpack Structure

In the last few days there has been a lot of fresh snowfall, often stormy NW winds transported the fresh fallen snow, generating large-sized trigger-sensitive snowdrift accumulations in many places. On Saturday night and during the day on Sunday, additional generally small-sized trigger-sensitive snowdrifts will accumulate due to the forecast 10cm of fresh snowfall.

Weather Forecast

Heavily clouded, cold weather with light snowfall during the morning hours. In the afternoon, relatively dry, but still heavy cloud cover in the mountains, or even foggy. Bright intervals expected only in the large valleys. On Sunday night it will remain dry. Northerly winds will intensify the cold. Temperature at 2000m: from -8 degrees; at 3000m: -15 degrees. Brisk northerly winds at high altitude.

Tendency

As a result of fresh snow and winds, avalanche danger will increase starting on Monday.
