Snow conditions in the mountains 19.3.2013
19.03.2013
Yesterday it snowed in the mountains, the snow line occasionally rose to around 1200 m above sea level in some places. The most precipitation was between the Julian Alps and Snežnik. In the Julian Alps, 40 to about 70 cm of snow fell, elsewhere 20 to 40 cm, less on the east.
A strong south to southwest wind blew, transporting snow into drifts. Already during snowfall, avalanches of fresh, unbonded snow were released.
At 2500 m there is currently around 420 cm of snow in the Julian Alps, at 1500 m up to 270 cm and at 1000 m 80 to about 100 cm. Elsewhere in our mountains, snow at 1500 m is 90 to 160 cm, at 1000 m up to about 50 cm.
The snow cover is soft and powdery, only on wind-exposed locations somewhat wind-packed in places. There are many drifts and slabs.
Avalanche danger has increased to 4th degree in the Julian Alps, elsewhere mostly 3rd degree. In the Julian Alps, spontaneous avalanches are expected, possibly larger ones and numerous smaller ones, especially from steep and moderately steep slopes. Elsewhere, spontaneous sliding is also possible especially from steeper slopes. Even with minor additional load, a new snow avalanche can quickly release even on places with wind-loaded snow.
The snow cover will settle slowly. Freezing level will be at elevations between 1000 and 1300 m. Snow will transform faster in sunny weather, even above the zero isotherm elevation.
Today it will be partly clear, possible some snow shower.
Weak to moderate west to southwest wind will blow, creating new drifts on exposed locations.
New report will be issued on Wednesday, 20.3.2013
General avalanche danger is 4th degree on the European five-level scale.
