Danger level


Avalanche Problem
Wet snow


Avalanche danger is mostly low. Slides and glide-snow avalanches due to higher temperatures.

Isolated danger zones are evident in extremely steep terrain. Small avalanches are possible there. Apart from the risks of being buried in snow masses, the danger of being forced to take a fall also requires consideration. Particularly on sunny slopes, moist loose-snow slides are possible. On steep grass-covered slopes where snowfall has been heavier, small glide-snow avalanches are also possible.

Snowpack

Due to milder temperatures, the snowpack has settled further and been able to consolidate. Fresh snow and drifts from recent days are generally well bonded with the old snowpack surface. During the daytime the uppermost layers are weakened due to higher temperatures and solar radiation. All in all, the snow depths are below average.

Tendency

Avalanche danger levels are not expected to change significantly. Slides and small glide-snow avalanches are still possible.

Weak layers in the old snow are the major danger. Slides and small glide-snow avalanches due to higher temperatures.

At high altitudes, older snowdrift accumulations and weak layers are often still prone to triggering. Danger zones occur mostly on shady slopes behind protruberances in the landscape, in gullies and bowls and on wind-loaded slopes. Size and spread tend to increase with ascending altitude. Small-to-medium slab avalanches can be triggered even by the weight of one single skier. At low altitudes and particularly on sunny slopes, moist loose-snow avalanches and small-to-medium glide-snow avalanches can trigger due to the higher temperatures.

Snowpack

Older snowdrift accumulations lie deposited mostely on steep shady slopes atop expansively metamorphosed layers or atop surface hoar. Bonding to the old snowpack surface is only moderate, with increasing altitude. At high-altitude levels on shady slopes and in places where the snow is shallow, faceted layers are evident in the snowpack. All in all, snow depths are highly varied, ridges are often uttler windblown or with little snow, gullies and bowls are filled to the brim with snow.

Tendency

Older snowdrifts and old snow at high altitude are the main danger. At low altitudes and particularly on steep sunny slopes, slides and small glide-snow avalanches are possible.
