Fresh snowdrift accumulations lie deposited atop unfavorable old snowpack surfaces. Danger zones often blanketed over.
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 2000m along the Italian border in the regions where snowfall has been heaviest. 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
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Particularly along the Italian border, about 15-20 cm of fresh snow was registered above 2000m, locally more. Rainfall made the snowpack wet widespread. Nocturnal outgoing longwave radiation is very limited. Winds have transported the fresh snow, also some of the old snow. Fresh snow and drifts lie deposited on shady slopes above 2000m atop an unfavorable old snowpack surface. In the lowermost part of the snowpack on shady slopes there are faceted weak layers evident.

Generally favorable avalanche situation, 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 bonding of fresh snow to old snow is generally good, the snowpack is often moistened and forms a thin melt-freeze crust during the night. During the course of the day, this crust softens, the surface becomes moist and can forfeit its bonding.
Tendency
Reduced nocturnal outgoing longwave radiation is leading to increasing wet-snow and snowdrift problems.

Only few avalanche prone locations (small avalanches).
Avalanche danger is low. Wet snow problem in all aspects. As the day progresses, isolated small wet loose snow avalanches can trigger naturally in extremely steep terrain at intermediate altitude. Smaller glide-snow avalanches can release on steep slopes over smooth ground. Further, isolated small snowdrift patches can be triggered as small slabs in steep high altitude terrain close to ridges in N/-E aspects.
Snowpack
Following clear nocturnal skies in many places the snowpack will be encrusted early in the day in all aspects at intermediate altitudes and on the sunny side at high altitudes. The snowpack surface will soften again during the course of the day and the bonding will become poorer. At higher altitudes the surface snow is still dry in shady terrain. At high altitudes, small fresh snowdrift accumulations occur in a few places.
Tendency
No significant changes.
Danger level
Isolated danger zones on wind-loaded slopes above 2000m
Due to fresh snow and moderate-velocity southerly winds, trigger-sensitive snowdrift accumulations have been generated esp. on NW/N/NE facing slopes, shallow and triggerable only in isolated cases. Wet loose-snow avalanches are hardly still possible. Most starting zones have already discharged.
Snowpack
Rainfall made the snowpack wet widespread. Nocturnal outgoing longwave radiation is very good in places. Sunshine and daytime warmth will soften the snowpack during the course of the day.

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.

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 2000m 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. On sunny slopes there forms a thin melt-freeze crust at night which softens during the daytime, becomes moist, and can forfeit bonding.
Tendency
Reduced nocturnal outgoing longwave radiation is leading to increasing wet-snow and snowdrift problems.

Snowdrifts at high altitudes, 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
