Slight increase in wet-snow avalanche danger below 2400m during daytime

Slight increase in wet-snow avalanche danger below 2400m during daytime

Predominantly favorable conditions and low danger prevail in the morning. Due to solar radiation and daytime warming, avalanche danger increases slightly below 2400m. Naturally triggered or low-additional-loading triggered small-to-medium wet-snow avalanches occur especially on E/S/W facing slopes. Backcountry skiing tours and activities in outlying terrain should be brought to an end early in the day. In regions where snowfall has been heavy on very steep grass-covered slopes, glide-snow avalanches continue to be possible. Caution below glide cracks. Weak layers in the old snow can often be triggered in high alpine regions, particularly by large additional loading small-to-medium avalanches can be triggered. Danger zones especially on very steep shady slopes.

During the cold, clear night with good outgoing radation a crust formed which is generally capable of bearing loads. The thoroughly moist snowpack stabilized superficially. On sunny slopes this crust softens during the day due to solar radiation and daytime warming, forfeits its firmness, increasing the danger of wet-snow avalanches somewhat. At low and intermediate altitudes there is not much snow on the ground. On shady slopes at high altitudes the snowpack remains frozen. In high alpine regions, partricularly on very steep shady slopes, there are still isolated danger zones for dry-snow avalanches; small-to-medium slabs can trigger in the near-surface layers or at the Sahara dust layer.

Sunny but cool weather prevails. Apart from high-altitude thin cloudbanks far above summit level, only harmless cumulus clouds are expected in the afternoon. Outstanding visibility. At 2000 m: -4 to +1 degree. Moderate northerly winds.

Sunny weather will persist in the next few days. The avalanche situation is generally favorable in early morning, then as the day unfolds, danger of wet-snow avalanches increases slightly due to solar radiation and daytime warming.
