Persistent weak layers
- All elevations
Low avalanche danger, only local avalanche prone locations
Low avalanche danger, only local avalanche prone locations
Low danger prevails in general. Dangerous places for dry-snow slab avalanches are limited to isolated, extremely steep, shady gullies above 2400 m. The glide-snow activity is receding, isolated releases on steep slopes over smooth ground cannot be ruled out. Therefore: avoid zones with glide cracks. In exposed terrain the snowpack surface is hard: risk of falling.
Up to high altitudes the snowpack is moist-to-wet, generally compact. Depending on altitude and aspect the melt-freeze crust can-or-cannot bear loads. Above 2400 m, local weak layers in the old snow can be triggered. At lower altitudes the snowpack is giving way to bare ground.
On Monday clouds will pass through the Northern Alps, the summits will often be shrouded in fog. Minor rainfall or snow showers in the eastern sector of the Northern Alps are expected. Temperatures will drop noticeably, the snowfall level descend to 1500m. At 2000 m at midday: -2 degrees; at 1500 m: +1 degree. Strong (in north and east, stormy) westerly winds. The further weather development will be turbulent. On Tuesday, a SW air current will bring mild temperatures, especially to northern regions, but it will remain dry. On Wednesday, a cold front and a low over the Mediterranean will make deep-wintery conditions return, dropping temperatures and fresh snowfall.
Until Tuesday hardly any change. As of Wednesday, increase in danger due to new snow and wind.
