Due to fresh snow, likelihood of slab avalanches above 1800m. Avalanches can trigger in gullies, bowls, behind protruberances in the terrain in the near-surface layers, even by one sole skier. Also isolated naturally triggered avalanches are possible, more so if the precipitation intensifies, esp. at the foot of rock walls. Avalanches can trigger in the old snowpack and grow to medium size. Whumpf noises and naturally triggered releases are alarm signals, indicators of imminent danger. Below 1800m: naturally triggered wet-snow avalanche activity will increase with the beginning of rainfall. In starting zones which have not yet discharged, small-to-medium wet loose-snow avalanches are possible. The runout zones should be circumvented, esp. on extremely steep slopes below 1800m in all aspects.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Since Monday, especially along the Italian border, about 15-20 cm of fresh snow was registered above 2000m, locally more. Above 1800m 15-30cm of fresh snow is anticipated widespread. Winds will transport the fresh snow. Fresh snow and drifts will be deposited on shady slopes above 2000m atop an unfavorable old snowpack surface. Rainfall in all aspects will lead to increasing wettening of the snowpack below 1800m.

Beware snowdrifts
Due to fresh snow and moderate-velocity southerly winds, trigger-sensitive snowdrift accumulations have been generated esp. in ridgeline terrain, in gullies and bowls, esp. above 2400m. Avalanches can be triggered by persons in the uppermost layers. In addition, isolated avalanches can fracture down to deeper layers of the snowpack and then grow to medium size. In starting zones which have not yet discharged, mostly small wet loose snow avalanches are possible, and can be triggered by winter sports enthusiasts. Caution urged in extremely steep slopes below 2000m. In addition, in the major areas of precipitation, isolated mostly small glide-snow avalanches are possible.
Snowpack
Since Monday above 2000m, 2-5 cm of fresh snowfall has been registered, locally more. Widespread 10-15 cm of fresh snow is anticipated. Winds will transport the fresh snow and some of the old snow. Fresh snow and drifts will be deposited on shady slopes above 200m atop an unfavorable old snowpack surface. In the lowermost part of the snowpack on shady slopes, faceted weak layers are evident. Below 2200m: nocturnal outgoing longwave radiation is heavily reduced. The snowpack surface softens up during the course of the day.

Avoid snowdrift accumulations on steep shady slopes
Avalanche danger is low. Small slab avalanches can be triggered by one sole skier in a few steep spots. Danger zones occur above 2200m esp. on NW/N/NE facing slopes, on occasion distant from ridgelines. Caution urged esp. at entry points into very steep gullies and bowls. During the course of the day, naturally triggered loose-snow avalanches can be expected in extremely steep south-facing terrain below 2200m. On steep grass-covered slopes, isolated small glide-snow avalanches are possible in isolated cases.
Snowpack
The snowpack surface is highly diverse. On shady slopes the expansively metamorphosed surface can serve as a potential weak layer beneath the snowdrift patches.

Caution: wet loose-snow avalanches. Runout zones should be circumvented.
Naturally triggered activity of wet-snow avalanches will increase as rainfall sets in. In starting zones which have not yet discharged, small-to-medium wet loose-snow avalanches are possible. The runout zones should be circumvented, esp. on extremely steep slopes below 1800m in all aspects. Due to fresh snowfall and often strong-velocity winds from the south, trigger-sensitive snowdrift accumulations will be generated esp. on ridgeline slopes, in gullies and bowls above 1800m. Avalanches can in isolated cases fracture down to more deeply embedded layers inside the snowpack and sweep them along. Avalanche releases are often medium-sized, triggerable by one sole skier. Rainfall will lead to an increased wettening of the old snowpack below 1800m in all aspects. Caution in gullies along the Slovenian border.

Rainfall in all aspects will make the snowpack generally wetter below 1800m. Since Monday, especially along the Slovenian border, about 5-10 cm of fresh snow was registered above 1900m, locally more. Above 1800m 15-20cm of fresh snow is anticipated widespread. Winds will transport the fresh snow. Fresh snow and drifts will be deposited on shady slopes above 2000m atop an unfavorable old snowpack surface.

In high altitudes danger spots are found in some places
Avalanche danger is in general low. In high altitudes danger spots in form of snowdrift deposits which are prone to triggering are found. There - in shady areas or adjacent to ridgelines small slab avalanches can be triggered. Ridgelines and summits are icy and hard. Be aware of risk of falling.
Snowpack
The snow base, which has a very low amount considering the season is predominantly stable. Depending on the exposition the snow cover ist moist or wet. Especially on sunny slopes only little amounts of snow is found even in high altitudes. In shady slops above 2.200 m loose snow is found in some places.
Tendency
Some showers coming from southwest are passing through, it will prtially sunny. The snow-line is 1.800 m.The little amount of new snow will not cause any significant change of the avalanche danger.

Only few danger zones
Avalanche danger is low. Isolated danger zones occur near ridgelines, esp. in steep shady terrain at summit level. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall demand adequate consideration. During the course of the day, small loose-snow slides continue to be possible. On steep grass-covered slopes, isolated small glide-snow avalanches are possible.
Snowpack
On shady slopes at high altitudes, isolated weak layers in transitions from old to fresh snow. On sunny slopes and at lower altitudes the snowpack is often 0-degrees isotherm.
Tendency
Initially no change. On Friday, more fresh snowfall.

Glide-snow/moist loose-snow avalanches during the daytime
Avalanche danger is low. In steep sun-bathed terrain, small moist loose-snow avalanches are possible. Above 2000m, mostly small avalanches can be triggered by winter sports enthusiasts in steep terrain. Danger zones occur esp. on steep shady ridgeline slopes. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. On steep grass-covered slopes with sufficient snow on the ground or atop smooth ground, increasingly frequent small-to-medium glide-snow avalanches are possible.
Snowpack
At high altitudes a few cm of fresh snow was registered. In the early part of the night, some clouds but mostly clear, so that a melt-freeze crust capable of bearing loads will be able to form, later in the day softening up, the snowpack will become superficially moist and forfeit its bonding. Foehn winds have deposited thin drifts on north-facing slopes which lie atop soft layers and are prone to triggering in places.
Tendency
On Wednesday temperatures will drop and snow showers will pass through, snowfall level at 1500m. No significant change expected

Caution: small-area snowdrift accumulations at high altitudes
Avalanche danger is low. Above 2200m, mostly small avalanches can be triggered by winter sports enthusiasts in steep terrain. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. On steep grass-covered slopes with sufficient snow on the ground or atop smooth ground, increasingly frequent small-to-medium glide-snow avalanches are possible.
Snowpack
At high altitudes a few cm of fresh snow is expected, to be deposited atop a well-consolidated old snowpack. On shady slopes, expansively metamorphosed, soft layers, otherwise often breakable wind crusts or melt-freeze crusts will be blanketed over. Bonding is generally good. On north-facing slopes at high altitudes, small-area, thin snowdrift accumulations atop soft layers could be prone to triggering.
Tendency
Avalanche danger will not change significantly before the next period of major precipitation.
Danger level
Wet loose-snow avalanches are hardly possible.
Wet loose-snow avalanches are hardly possible. Most discharging zones have already discharged.
Snowpack
Rainfall moistened the snowpack widespread below 2000m. Nocturnal outgoing longwave radiation will often be quite good. Sunshine and daytime warmth will lead to a softening of the snowpack during the course of the day on very steep sunny slopes in particular.
