Fresh snowdrift in high altitudes

Fresh snowdrift in high altitudes

The avalanche is above the treeline moderate and below that low. New snow and northerly winds fresh danger spots are forming with snowdrift. These are prone to triggering especially in the expositions north via east till west. They can be triggered by individuals as slab avalanche. The danger spots are increasing during the course of the day. The new snow can be triggered as spontaneous loose-snow avalanche from extremely steep areas with few winds. In places of steep areas wet loose-snow avalanches are possible.

By Saturday evening, 10-30 cm of new snow will fall, and locally even more. Depending on wind influences, driftsnow deposits of varying thickness will form over the course of the day, often sufficiently bonding with the existing old snowpack. With increasing altitude, weak layers (isolated) will form soft layers in the near-surface old snowpack (on the shady slopes) and primarily in the bonded layer. In some places, rain may lead to a loss of snowpack strength.

With the occlusion of a low-pressure system over central Italy, moist air masses are being brought in from the southeast. On Saturday, precipitation will initially affect the western foothills of Styria, with the focus shifting towards the northern flank of the Alps by the afternoon. The snow line will be at approximately 1.400 m, reaching 1.000 m in the evening in the Ausseerland region. Midday temperatures will be -2 degrees at 2.000 m and 0 degrees at 1.500 m. Easterly winds will initially remain light, but will strengthen by the evening as the wind shifts to the north. With dense, low-level cloud cover, most summits will be shrouded in fog.

Precipitation will intensify again overnight into Sunday, and during the day the showers will retreat to the northern areas, while the south will experience favorable weather conditions from midday onwards due to the northerly foehn winds. The avalanche danger will increase slightly depending on the amount of new snow.
