As the day progresses a moderate danger of wet avalanches will be encountered over a wide area

Individual avalanche prone locations for dry avalanches are to be found in particular on extremely steep slopes at high altitude. They are to be evaluated with care and prudence in particular in extreme terrain. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.

Clear skies during the night will give rise to a strong crust on sunny slopes over a wide area. Warming and solar radiation during the day will thaw the crust and weaken the snowpack. Both wet snow and gliding avalanches can occur. In particular in southern Valais and the inneralpine and southern regions of Grisons, distinct weak layers exist deep in the snowpack. These will respond especially sensitively as moistening begins. In the indicated places, moist and wet snow avalanches can release deep layers of the snowpack or be initiated directly in these layers. They can also be released by people in some cases. The snowpack is thoroughly moist on south facing slopes below approximately 2800 m, on east and west facing slopes below approximately 2300 m, and on north facing slopes below approximately 1600 m.

On Sunday night, the skies were partly cloudy on the southern flank of the Alps, but otherwise predominantly clear. It was mostly sunny during the day despite some high-altitude cloudbanks. Fresh snow: - Temperature: At midday at 2000 m: between 0 °C in the west and -2 °C in the south and east Wind: Mostly light to moderate from the south to east After a clear night, the day will be sunny. Fresh snow: - Temperature: At midday at 2000 m: about 0 °C Wind: Light to moderate from the south to southeast

On each of the coming days, it will be mostly clear at night and sunny during the daytime. The zero degree level will rise to approximately 2500 m. The avalanche situation will be favourable in the morning. The danger of wet snow and gliding avalanches will increase during each of the coming days.
