Avalanche Activity

Snowdrifts prone to triggering

Avalanche danger is CONSIDERABLE. Fresh ridgeline snowdrift accumulations can trigger by 1 person above 2200 m on steep shady slopes, releases often medium-sized. Danger zones will increase with ascending altitude, also distant from ridges, in steep gullies and bowls and behind discontinuities on N/E/SE facing slopes. In case of solar radiation, small loose-snow avalanches can trigger naturally in steep (>40°) terrain, in places can be triggered by 1 person.

Snowpack Structure

Atop a thoroughly moist snowpack, 50-80 cm of cold fresh snow lie deposited. In transitions from the old snowpack to the fresh snow masses, bonding is good, but poor in the upper layers of the fresh snow, due to wind impact. Weak layer! Reserves of cold in the old snow are limited to shady slopes above 2600 m. Gliding snow activity has receded.

Weather Forecast

On Friday night, 5-10 cm of fresh snow is expected, on Saturday the peaks will be veiled in clouds and repeated bouts of snowfall are expected (5-10 cm) during the day. Visibility severely reduced. Winds moderate to brisk from the northwest. At 2000m: -7 degrees; at 3000 m: -13 degrees.

Tendency

Snowdrift accumulations will quickly consolidate.
