On the northern flank of the Alps, rain fell up to 2800 m. In the other regions on the main Alpine ridge and to the north,
it rained up to approximately 2600 m. In consequence, the snowpack became thoroughly moist up to high altitudes or, in areas
close to the snowfall level, at least the near-surface layers of the snowpack became moist. At elevated altitudes, the strong
to storm force northwesterly wind transported large quantities of the fresh snow and in some cases the old snow as well.
The warm and moist snow is settling quickly. In addition, with clear night skies, the snow surface will freeze on Thursday
night, which will promote the rapid stabilisation. In places where the snowpack remained dry, namely in the high Alpine regions
on the northern flank of the Alps and elsewhere above approximately 2600 m, the snowpack is stabilising more slowly. Furthermore,
from central Valais through northern Ticino to Grisons, the fresh snow and snow drift accumulations are lying on weakly bonded
old snow and remain prone to triggering at elevated altitudes in these regions in particular.
