Hidden persistent weak layer problem

Avalanche danger above 2200m is moderate, below that altitude danger is low. In few places, an avalanche can be triggered by one sole skier as a slab avalanche. Danger zones are nearly impossible to recognize, most critical behind protruberances in the landscape and in gullies and bowls. Fresh drifts on some ridgeline slopes can be easily triggered as a small slab. The wind-loaded zones are easily recognized, watch out for the risks of falling. On very steep sunny slopes, small loose-snow avalanches are possible. Isolated small naturally triggered glide-snow avalanches are possible.

Snowpack

Atop a hardened crust (or else, bare ground) 10-30 cm of loosely-packed snow lie deposited, often wind impacted. On shady slopes at high altitudes the fresh snow from Friday has also been deposited atop loose snow or surface hoar. The fundament on steep shady slopes at high altitudes is expansively metamorphosed. Atop a hardened crust (or else, bare ground) 10-30 cm of loosely-packed snow lie deposited, often wind impacted.

Circumvent small-scale snowdrifts. Danger of falling outweighs that of being buried in snow masses.

Avalanche danger is moderate above 2000m, below that altitude danger is low. Snowdrifts are the main problem. Slab avalanches that are mostly small can be triggered by minimum additional loading. Avalanche prone locations are found in steep ridgeline terrain in NW-E-SE aspects and in wind-loaded gullies and bowls. The frequency of avalanche prone locations increases with ascending altitude.

Snowpack

On the shady side the snowpack surface is powdery. In ridgeline terrain, small-scale snowdrifts will accumulate during the course of the day which will partly be deposited atop loose snow layers. The snowdrifts are prone to triggering. At high altitudes there are still layers consisting of faceted crystals more deeply embedded in the snowpack close to crusts. However, these are now very unlikely to trigger. At intermediate altitudes the old snowpack is thoroughly moist, wet at the ground in places.

Tendency

Avalanche danger levels will recede slowly.

Caution: isolated weak layers prone to triggering. Heed drifts.

Weak layers in the old snow can be triggered in many cases by one sole skier on W/N/E facing slopes above 2400m. Caution in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls. Due to fresh snow and northerly winds, trigger-sensitive snowdrift accumulations were generated in gullies, bowls and behind protruberances in the landscape. They can be triggered by one sole skier in the weak old snow, esp. on W/N/E facing slopes above 2400m. Danger zones are easy to recognize for the practiced eye. Avalanches can reach medium size.

Snowpack

dp.6: cold, loose snow and wind
dp.4: cold following warm / warm following cold

In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers, esp. on W/N/E facing slopes. The fresh snowdrift accumulations lie deposited atop an unfavorable old snowpack surface in high-alpine zones. Highly varied snow depths, depending on wind impact.

Tendency

Fresh snowdrifts need to be cautiously assessed. Pay attention to weak layers in old snowpack.

Assess fresh snowdrift accumulations with caution

Avalanche danger above 2000m is moderate, below that altitude danger is low. Freshly generated snowdrift accumulations can in some places be triggered by one sole skier as a slab avalanche. Releases tend to be small-sized. Danger zones occur esp. near ridgelines, behind protruberances in the landscape and in gullies and bowls, usually they are easy to recognize. On very steep shady slopes, weak layers can fracture and be swept along. Caution urged esp. at entry points into very steep gullies and little skied-on north-facing slopes. On extremely steep slopes, small loose-snow avalanches can be expected. Isolated small naturally triggered glide-snow avalanches are possible.

Caution: freshly generated snowdrift accumulations.

Due to fresh snow and moderate northerly winds, often trigger-sensitive snowdrift accumulations have been generated in ridgeline terrain, gullies and bowls and behind protruberances in the landscape. These drifts can be triggered in many cases by one sole skier ib NW/N/SE facing slopes above 1800m. In addition, isolated avalanches can trigger in the weak old snow, esp. on W/N/E facing slopes above 2200m. Caution urged in transitions from shallow to deep snow, e.g. at entry points into gullies and bowls. Caution in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls.

Snowpack

dp.4: cold following warm / warm following cold
dp.1: deep persistent weak layer

Since Friday there has been 15-30cm of fresh snow registeres, locally more. Winds have transported the fresh fallen snow. The fresh snowdrift accumulations lie deposited atop an unfavorable old snowpack surface, in the lower part of the snowpack (esp. on W/N/E facing slopes) are faceted, expansively metamorphosed weak layers. Very steep south-facing slopes: due to lower temperatures and low air moisture, a crust will form on the surface during the night. Weather conditions will lead to a moistening of the snowpack as of midday.

Tendency

Fresh snowdrifts need to be cautiously assessed. Pay attention to weak layers in old snowpack.

Main danger: freshly generated snowdrift accumulations

Due to fresh snow and northerly winds, often trigger-sensitive snowdrift accumulations have been generated in ridgeline terrain, gullies and bowls. These drifts can be triggered in many cases by one sole skier in all aspects above 1800m on N/NW/E facing slopes. Danger zones are easily recognized to the practiced eye. Avalanches can reach medium size.

Circumvent fresh drifts.

Avalanche danger is moderate above 2000m, below that altitude danger is low. Snowdrifts are the main problem. Slab avalanches that are mostly small can be triggered by minimum additional loading. Avalanche prone locations are found in steep ridgeline terrain in NW-E-SE aspects and in wind-loaded gullies and bowls. The frequency of avalanche prone locations increases with ascending altitude. On very steep slopes over smooth ground, it cannot be excluded that smaller glide-snow avalanches can release spontaneously.

Snowpack

On the shady side the snowpack surface is powdery. In ridgeline terrain, small-scale snowdrifts will accumulate during the course of the day which will partly be deposited atop loose snow layers. The snowdrifts are prone to triggering. At high altitudes there are still layers consisting of faceted crystals more deeply embedded in the snowpack close to crusts. However, these are now very unlikely to trigger. At intermediate altitudes the old snowpack is thoroughly moist, wet at the ground .

Tendency

Avalanche danger levels will recede slowly.


Danger level



Fresh snowdriftrs. Isolated danger zones in gullies and bowls.

Fresh snowdrift accumulations are mostly small, triggerable only in isolated cases, esp. on wind-protected shady slopes at high altitude. Caution urged in transitions into gullies and bowls. These danger zones occur seldom.

Snowpack

Since Friday, fresh snow (10-15cm) has been registered. Freshly generated snowdrift accumulations have been deposited on top of an unfavorable old snowpack surface.

Tendency

Pay attention to fresh snowdrifts


Danger level



Favorable situation

Avalanche danger is low. Triggering a small slab is possible in only few places, most endangered are shady slopes in very steep terrain above 2000m. In isolated cases a small glide-snow avalanche is possible. Isolated small naturally triggered glide-snow avalanches possible.

Snowpack

Atop a melt-freeze crust (or else, bare ground) loosely-packed snow lies deposited. Surface hoar has often been blanketed. On sunny slopes the snow is sticky. The fundament on shady steep slopes is often weak, but the weak layer is varied and the slab shallow.

Tendency

No significant change in danger levels anticipated

Watch out for small snowdrift accumulations

Snowpack

Tendency

Avalanche danger levels will slowly recede.


Danger level



No significant change of the avalanche danger. Caution: snowdrift accumulations in shady areas!

Still low avalanche danger. Dander spots can be located in high altitudes in the expositions north to east and behind ridgelines. There slab avalanches could be triggered in extremly steep slopes by high additional loads.

Snowpack

In high altitudes small amounts of snowdrift accumulations have formed which partially are on top of faceted snow. The new snow is covering an old snow cover which weakened due to kinetic metamorphosis in high altitudes it is on top of a hard old snow cover.

Tendency

The avalanche danger is not significantly changing. Tuesday will be predominantly sunny. Some clouds are passing through during the day. It will stay cold in high altitudes.


Danger level



Shallow snowdrifts in isolated cases avalanche prone

Avalanche danger is low. Snowdrifts can be problematic. Isolated small snowdrift accumulations can be triggered by minimum additional loading in steep terrain adjacent to ridgelines in W-E-SE aspects. Dangers of being swept along and of taking a fall outweigh those of being buried in snow masses. In particular in the Allgäu region it cannot be excluded that isolated smaller glide-snow avalanches trigger naturally on very steep slopes with smooth ground.

Snowpack

On the shady side, the snowpack surface is loose and powdery. In ridgeline terrain, isolated small-scale snowdrifts will accumulate during the course of the day. These will partly be deposited atop loose snow layers and can be prone to triggering. The old snowpack is thoroughly moist, wet at the ground.

Tendency

Avalanche danger levels will remain low.
