The snow level in the northern regions on north-facing slopes lies at 800 to 1200 m, in the southern regions at 1200 to 1800
m. On south-facing slopes the snowl levels lie approximately 500 m higher up, in the southern valleys of Visp even higher
still in some places.
The snowpack is thoroughly wet on south-facing and west-facing slopes below approximately 3200 m, on east-facing slopes below
approximately 2800 m, and on north-facing slopes below approximately 1800 m. In the uppermost third of the snow cover in many
regions, a marked weak layer is evident. This layer is located generally in the vicinity of the layers of dust blown north
from the Sahara desert in February.
On Saturday night on east-facing, south-facing and west-facing slopes, a melt-freeze crust capable of bearing loads will form
on the snowpack surface. As a result of daytime warming and solar radiation on Easter Sunday, wet-snow avalanches will be
possible during the course of the day, including even large-sized releases in isolated cases. On high-altitude north-facing
slopes, dry-snow avalanches can still be triggered in isolated cases.
