AVOID: small snowdrift accumulations and zones below glide cracks

AVOID: small snowdrift accumulations and zones below glide cracks

Avalanche danger is low. At high altitudes, fresh small snowdrift accumulations will be generated, often triggerable by 1 person. The dnager of falling outweighs that of snow masses. Latent danger of glide-snow avalanches persists. In high starting zones, avalanches can reach medium-to-large size. Avoid zones below glide cracks.

Fresh drifts will bond well with the old snowpack surface, weak layers can form inside the drifts and be prone to triggering. In the nighttime hours a melt-freeze crust capable of bearin loads can form, in the morning there will be firn snow.

In the early part of the night, clouds are heavy, after midnight clouds will disperse. On Saturday a marked cold front will move in. In early morning skies will be clear, later clouds will move in, bringing heavy showers, storm-strength winds. In the Northern Alps, gusts of 80-100 km/hr are expected, in exposed terrain more. From Tennengebirge southwards, winds will be weaker, but still reach 100 km/hr. Snowfall level will drop rapidly, in evening lie at 1000 m. At 2000 m: dropping from +4 to -2 degrees; at 3000 m: from -3 to -7 degrees. The cold air masses will move more into northern than into southern regions. All in all: at 1500 m 10-20 cm of fresh snow, more on the Main Alpine Ridge.

Avalanche danger levels are not expected to change significantly.
