Wet snow
- All elevations
Some fresh snowfall and drifts at high altitudes, starting at midday
The old snowpack is thoroughly moist and wet down to the ground. The surface freezes at night depending on cloud cover and thus, nocturnal outgoing radiation is insufficient to consolidate it, only a thin melt-freeze crust can form which then quickly softens. Due to strong warmth impulse, the snowpack rapidly loses its firmness in the morning hours and weakens the snowpack. At low altitudes the snow will fall on bare ground.
Nocturnal hours: high clouds and Sahara dust will reduce outgoing radiation. Very mild air masses. Tuesday daytime: Precipitation expected towards midday, swiftly spreading thorughout the mountain regions, snowfall level dropping quickly to 1000 m. At 2000 m: from +10 to -4 degrees. Strong to stormy southerly winds, shifting to westerly in afternoon and slackening off.
Wednesday will be variably cloudy with light snowfall at 1000 - 1400 m. In afternoon the snowfall will taper off, towards evening the clouds will disperse. Danger of dry-snow avalanches will not change significantly. Danger of wet-snow avalanches will recede noticeably. Glide-snow avalanches remain unpredictable.
Some fresh snowfall and drifts at high altitudes, starting at midday
Due to striking rise in temperatures and solar radiation, increasingly frequent slides and avalanches can be expected in very steep terrain, the danger of glide-snow avalanches will also increase, releases small-to-medium wherever there is sufficient snow on the ground. The danger of dry-snow avalanches is low, isolated triggerings are possible in extremely steep terrain. Beware the dangers of taking a fall.
