Snowdrift problem at high altitude. Glide-snow avalanches during the afternoon.

Snowdrift problem at high altitude. Glide-snow avalanches during the afternoon.

Avalanche danger in the morning is LOW, rises to MODERATE in the afternoon. Morning: the older snowdrift accumulations can in isolated cases be triggered by one sole skier on very steep (>35°) shady slopes, avalanche releases mostly medium, isolated large-sized releases when deeper layers are swept away. Afternoon: due to higher temperatures, moist air masses and rainfall, small-to-medium sized naturally triggered wet-snow and glide-snow avalanches are possible below the snowfall level. Isolated avalanches on shady slopes can grow to large size.

During the night of partly clear skies, a thin melt-freeze crust will form then rapidly soften during the day. Higher daytime temperatures and moist air masses will lead to a further softening of the snowpack. In the afternoon, rainfall below 2200-2500 m will moisten and weaken the snowpack. At higher altitudes, 20-40 cm of fresh snow is possible. Winds will be light to moderate. Snowdrift accumulations from the last few days have consolidated well for the most part, are adequately bonded with the layers beneath them, only on shady slopes at high altitudes are they still prone to triggering. On shady slopes, isolated faceted layers are evident inside the old snowpack.

On Friday, initially dry with scattered clouds and some sunshine. Later, clouds will move in, visibility deteriorate. In late morning, rainfall and snowfall will spread, the snowfall level in the afternoon will lie at 2200-2500 m. Westerly winds will be light to moderate, but gradually intensify in the high alpine regions. At 2000 m: 2-4 degrees; at 3000 m: -2 degrees.

Wet snow remains the main problem.
