Starting in early morning: considerable avalanche danger
The snowpack is weak up to high altitudes, partly due to lack of nocturnal shortwave outgoing radiation, partly due to rainfall and mild temperatures. In very steep terrain in all aspects, wet slides and avalanches can be expected. These releases can grow to large size. On steep snow-covered grassy slopes, glide-snow avalanches are possible. Caution below glide cracks in the surface of the snowpack. In addition, medium-sized avalanches can be triggered in older snowdrifts, as well as on high-altitude shady slopes in the weak old snow, by winter sports enthusiasts.
The old snowpack us weak up to over 2000m already in the early morning hours. During the daytime, mild temperatures and solar radiation make the snowpack wetter, rapidly leading to a further loss of firmness. Above the timberline, older snowdrift accumulations are frequently prone to triggering. On steep, shady high-altitude slopes, the old snowpack often has unfavorable intermediate layers and a poorly-structured fundament.
During the nighttime hours, cloud cover will rapidly move in from the northwest, frequently bringing heavy rain showers. Monday will start with dense, heavy low-lying clouds and final showers. Later in the morning conditions will become more pleasant. Temperature at 2000m: from 1 to 6 degrees; at 3000m: -4 to 0 degrees. Brisk-to-strong westerly winds at high altitude.
