Avalanche Activity

Heightened wet-snow danger from early morning, depending on nocturnal cloud cover

Danger of wet-snow avalanches is heightened even as of early morning, particularly on very steep north-facing slopes at 1800-2400m. As a result of daytime warming and solar radiation, avalanche danger quickly increases, in all aspects below 2400m, on on very steep sunny slopes up to high altitudes. Naturally triggered avalanches can be expected, avalanches can also be triggered by persons and grow to large size, also sweep along great amounts of wet snow in their plummet path and then extend to very long runout zones. In high alpine regions, small ridgeline snowdrift accumulations are still prone to triggering. In addition, winter sports enthusiasts can in places on high-altitude shady slopes trigger near-surface weak layers. Such danger zones are impossible to recognize. Atop the hardened snowpack surface, there is danger of being forced to take a fall on steep slopes.

Snowpack Structure

Following reduced outgoing radiation and mild temperatures, the snowpack is hardly freezing at night. At altitudes of 1800-2400m the snowpack, even on north-facing slopes, is thoroughly wet and ground-level layers of rotten snow are prone to triggering already in early morning. In high-altitude, steep and shady terrain, there are unfavorable intermediate layers in the uppermost metre of the snowpack which in places are prone to triggering. A thick mid-section of compact layers blankets the deep hoar and faceted crystals at the base of the snowpack.

Weather Forecast

High and intermediate clouds will pass through during the night. In SE regions, better outgoing radiation. Foehn-conditions, predominantly sunny from Lechquellen mountains and southwards therefrom in the morning, but quite windy. Strong convective cloud build-up during daytime, tendency towards thunderstorm-like showers will increase later in the day. Temperature at 2000m: 3 to 7 degrees; at 3000m: 0 degrees. Moderate to brisk south-to-southeasterly winds at high altitudes.

Tendency

Until and including Monday, mild temperatures will continue with heavily clouded skies. The snowpack cannot firm up at night.
