Fresh snow, later rainfall into the snowpack
Fresh snow, later rainfall into the snowpack
In the regions where snowfall has been heavy along the Styrian rimline range from Koralm over Stubalpe and Gleinalpe to the Fischbach Alps and Wechsel, the fresh snow can begin to glide over steep bare slopes, esp. if rainfall continues. Small-to-medium glide-snow avalanches cannot be ruled out. Trigger-prone snowdrifts are being generated above the treeline, esp. behind discontinuities on west-facing slopes.
The forecast snowfall in the Styrian rimline range will initially be loose powder, later moist, and at low altitudes wet snow or rain. Near the slopes which were already bare, bonding to the warm ground is poor. In isolated cases at high altitudes, fresh snowdrifts can be deposited.
As a result of a low pressure front over Italy, moist air masses are moving into southeastern Styria. On Monday night in the Styrian rimline range snowfall will set in and persist into the day on Tuesday, snowfall level initially at valley level, then ascending to 1000 m. Most of the snowfall (up to 40 cm) is anticipated in the eastern barrier cloud regions at high altitudes of the Koralm, in northern and western regions of Upper Styria they will be far less. At 2000 m: -6 degrees; at 1500 m: -3 degrees, rising to +3 degreres in afternoon. The easterly winds will be moderate.
The low will move towards Slovakia, and with it the focus of precipitation will move to the northern flank of the Alps: glide-snow avalanches cannot be ruled out.
