Avalanche Activity

Driftsnow is prone to triggering even below the treeline line. Moderate avalanche danger but caution when choosing a route within the avalanche zones!

Moderate avalanche danger above 1.600m, below that low avalanche danger. Danger is caused by driftsnow accumulations adjacent as well as distant from ridgelines. Most danger spots are found in the sectors east and south behind ridgelines and in the beginning of gullies and bowls. Slab avalanches can be triggered by small additional loads. Avalanches can reach medium size.

Snowpack Structure

In the past days cold new snow has landed on wet snow or - in higher altitudes - powder snow. Around 30 cm new snow in the westerly Northalps which will be drifted due to the stormy northwesterly winds. The summits can be blown-off but driftsnow can accumulate below treeline. Soft layers within the snowdrift and poor bonding to the old snow base can be weak layers.

Weather Forecast

Clear, sunny mountain weather in the 26th. Excellent visibility! Temperatures in 2.000 m increase during the course of the day and will be around 1 degree at noon. Moderate to vivid winds coming from northeast.

Tendency

Decreasing windslab problems and avalanche danger.
