Avalanche Activity

Main problem: gliding snow

Avalanche danger is low on steep slopes. Glide-snow avalanches can trigger in all aspects at any time of day or night naturally as long as there is sufficient snow on the ground and grow to medium size, sometimes large size. Avoid zones beneath glide cracks. Apart from gliding snow problem, the greatest danger is from taking a fall.

Snowpack Structure

Due to good nocturnal outgoing radiation and dry air the snowpack was able to dry out and form a melt-freeze crust up to 1800 m, on south-facing slopes up to over 2000 m, which is capable of bearing loads. Firn snow on south-facing slopes during the daytime. On shady slopes, wind-crusts and sometimes still powder. Above 1900 m there are small snowdrifts deposited atop a crust, easily recognized, usually well bonded with the surface, unlikely to trigger. Due to warmth of the ground and moistness of the snowpack, increased glide-snow activity can be expected.

Weather Forecast

Star-studded skies on Tuesday night, dry air. On Wednesday, sunny weather, good for backcountry tours, though with some high-altitude cloudbanks passing through (good visibility). Only in the Osterhorn range will there be more cloud cover. Winds light to moderate, in afternoon in high-alpine regions brisk westerly winds in the Northern Alps. At 2000 m: 0 degrees; at 3000 m: -5 degrees.

Tendency

Avalanche danger levels are not expected to change significantly.
