Snowdrift accumulations generated over the last few days lie deposited on north-facing slopes atop expansively metamorphosed
(faceted) old snow and are prone to triggering in some places. The snowpack surface is coloured brown from the deposited Sahara
dust over widespread areas. Thereby, a smaller degree of solar radiation is reflected, which leads to a heightened degree
of warmth in the snowpack. Due to this warming over the last two days, numerous superficial avalanches were released naturally.
In the regions of the north where snowfall has been heaviest, increasingly frequent gliding avalanches have been observed.
More deeply embedded inside the snowpack in the southern Valais and in the inneralpine and southern regions of Grisons more
than anywhere else, there are pronounced weak layer evident. However, since the end of February, no fractures of dry-snow
avalanches have been recorded as triggering in these layers. As a consequence of the beginning moistening-of-the-snowpack,
fractures in these weak layers will once again become possible.
