Snowfall levels in the northern regions lie at 800 to 1200 m, in the southern regions at 1200 to 1800 m. On south-facing slopes
the snowfall levels lie approximately 500 m higher up; in the southern valleys of Visp, higher up 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. During Sunday night when skies will be clear,
a melt-freeze crust capable of bearing loads will be generated on east-facing, south-facing and west-facing slopes. As a result
of daytime warming and solar radiation on Easter Monday, isolated wet-snow avalanches are possible during the course of the
day.
On high-altitude north-facing slopes, isolated dry-snow avalanches can still be triggered.
