Recently generated snowdrift accumulations are evident particularly in the foehn-exposed regions of the north. The accumulations
have been deposited on north-facing slopes more than anywhere else, on top of expansively metamorphosed (faceted) old snow
and are prone to triggering in some places. In spite of strong-velocity southerly winds and foehn wind in many places, hardly
any further snowdrift accumulations are being generated, since there is simply too little snow to be transported.
More deeply embedded inside the snowpack in the southern Valais as well as in the inneralpine and the southern regions of
Grisons, there are pronounced weak layers evident. Since the end of February, however, no further avalanche releases have
been recorded as triggering in these layers.
In the eastern regions, the nocturnal longwave outgoing radiation is adequate, so that on steep south-facing slopes a crust
forms which is capable of bearing loads. In the remaining regions of Switzerland the nighttime outgoing radiation is reduced.
As a consequence of solar radiation and daytime warming, wet slides and gliding avalanches are possible north of an imaginary
Rhine-Rhone line on very steep, sunny slopes more than anywhere else..
In the southern regions there is unusually little snow on the ground, at numerous measurement stations less than has ever
before been measured at this juncture of the season. As a consequence of the shallow often expansively metamorphosed (faceted)
snowpack there is currently heightened danger of falling into crevices on the glaciers, most particularly in the southern
Valais and in southern Grisons.
