Be careful of fresh snowdrifts. Weak layers in old snow demand caution.

Fresh snow fall and strong-velocity northerly winds will generate trigger-sensitive snowdrift accumulations during the course of the day particularly on E/SE/S facing slopes above 2400m along the Salzburg border. Weak layers inside the old snow can be triggered by one sole skier in all aspects, particularly in gullies, bowls and behind protruberances in the landscape along the Salzburg border. On shady slopes and in high alpine zones the likelihood of triggering is higher. Caution urged especially in seldom-skied terrain. Whumpf noises and glide-cracks when you step onto the snowpack are indicators of danger. Avalanches can reach medium size. Magnitude and frequency of danger zones tend to increase with ascending altitude.

Snowpack

dp.6: cold, loose snow and wind
dp.1: deep persistent weak layer

Up to 5-10 cm of fresh snow was registered, the freshly generated snowdrift accumulations above 2400m were deposited atop an unfavorable old snowpack surface by easterly winds. The older snowdrifts blanket a weak layer particularly on shady slopes above 2400m. The snowpack is highly diverse even over small areas.

Tendency

Gradual decrease in avalanche danger


Danger level



Little snow on the ground.

Older snowdrift accumulations can in isolated cases be triggered by large additional loading on shady slopes. Isolated danger zones occur on shady slopes and in gullies and bowls above 1900m.

Snowpack

The old snowpack is expansively metamorphosed.

Tendency

No significant change expected in avalanche danger levels

Weak layers in the old snow demand high caution

Weak layers in the old snow in all aspects can be triggered by one single skier and are expected to remain trigger-sensitive. Danger zones occur esp. in gullies and bowls and behind protruberances in the landscape above 1800m and at the foot of rocky cliffs. Whumpf noises and glide cracks when you step onto the snowpack are indicators of danger. Avalanches can grow to medium size. Magnitude and frequency of danger zones will tend to increase with ascending altitude. Risks of being forced to take a fall or being swept along require consideration.
