Weather Forecast

A Mediterranean low will bring mild, moist air masses to Styria on Tuesday. The SW airstream is full of clouds, few bright intervals are expected. On the southern flank of the Alps during the course of the day, minor precipitation, snowfall level at 1500 m. The SE/SW winds will be mostly light, brisker on the eastern rim of the Alps. At 2000 m: +1 degree; at 1500 m: +4 degrees Also on Wednesday, the SW airstream will continue. A bit milder. Above 2000 m minor snow showers are possible.

Tendency

Gliding snow and wet snow activity will increase somewhat, the snowdrift problem will recede.

Snowpack Structure

The snowpack base is stable by and large, but moist down to the ground, which means it can glide over smooth ground. Since Friday there has been up to 45 cm of fresh snow registered, often transported by southerly winds and deposited as snowdrifts on north-facing slopes atop soft layers of fresh snow and is often instable.

Avalanche Activity

Moderate avalanche danger above treeline

Avalanche danger above the timberline is moderate, below that altitude danger is low. Particularly critical: wind-loaded gullies and steep slopes in extended northern aspects, since the drifts here lie deposited atop loose fresh snow. Medium-sized slab avalanches can be triggered by 1 person. In addition, isolated medium-sized naturally triggered avalanches are possible. In addition, isolated naturally triggered glide-snow avalanches possible in all aspects.
