Wet snow avalanches detach up to the summit areas

Wet snow avalanches detach up to the summit areas

The avalanche risk is moderate. The melt-freeze crust at higher elevations is softening quickly. Wet loose snow and slab avalanches are already possible in the morning on slopes that have not yet been unloaded, with the danger increasing again slightly in the afternoon. This is the case in those aspects where there is still a lot of snow. Avalanches can occur naturally or be triggered by winter sports. They usually remain medium in size, but with the accumulation of wet snow and tearing through to weak layers close to the ground, large avalanches are conceivable in exceptional cases. Caution should also be exercised in the shallow outlet areas of trenches. Small gliding sluffs are occasionally recorded.

Trigger points for dry old snow avalanches are only present at a few high points in the extended northern sector.

The snowpack cools down poorly overnight, only at high altitudes does a thin melt-freeze crust form, which softens quickly. Underneath is compact snow, but on shady slopes from around 2200 metres there are still weak layers of deep rime in the old snowpack near the ground. The snowpack will become moist to wet up to high altitudes during the daytime changes at the latest. Low and sunny slopes are snowed out.

It may still be clear at the highest altitudes during the night, after which the clouds will thicken. The frost line will be around 2600 metres. Tomorrow, Thursday, there will be mostly dense clouds, especially in the morning, but the sun may appear at high altitudes, and in the afternoon the sun will shine more frequently. A few spring clouds will form over the peaks. Light rain showers are possible everywhere in the morning (frost from approx. 2500 m), with isolated showers in the northern Alps in the afternoon. The wind will be weak to moderate, in the afternoon partly brisk from north-westerly directions. Temperatures at 2000 m around 4 degrees, at 3000 m around -3 degrees.

The night to Friday will be mostly clear and there will be pronounced daytime changes.
