Frequent natural triggerings from the ground

Afternoon

Morning

Following a night of rainfall up to high altitudes, unfavourable conditions from the start on Tuesday: numerous natural triggerings up to 2700 m, some from the ground. Most of the remaining snow is in the Hohe Tauern, danger there is CONSIDERABLE, elsewhere danger is MODERATE.

Avalanche Danger

Avalanche danger in the Tauern on Tuesday is CONSIDERABLE from the start, elsewhere danger is MODERATE, with a slight daytime danger curve.

WET SNOW: Likelihood of naturally triggered avalanches (gliding snow, wet snow) will rise already in the morning. Many avalanches will be small-to-medium, some will probably be large. All aspects are at risk below 2300 m; on E-S-W facing slopes below 2700 m. In extremely steep terrain, wet loose-snow avalanches can be triggered by skiers.

SNOWDRIFTS: In high alpine regions above 2700 m, conditions are generally better, with relatively few avalanche prone locations for dry-snow slab avalanches on extremely steep, NW-NE facing ridgeline slopes.

Snow Layering

At high altitudes (at least above 2500 m) there is a small amount of fresh snow. Below that layer, the snowpack is 0-degrees isotherm, due to warmth and rain seepage, and quite moist/wet below 1800 m. Following a night of overcast skies and precipitation, the cold reserves are nearly used up. The activity area for gliding-snow and wet-snow avalanches is currently on north-facing slopes at 1700-2300 m; on south-facing slopes at 2100-2700 m. Above 2700 m the snowpack is currently rather stable, excluding the small fresh snowdrift patches in gullies and near ridgelines.

Alpine Weather Forecast (ZAMG Salzburg)

Skies on Monday night will be overcast, intermittent rainfall is expected up to high altitudes. It will remain dry in the Nockberge.

On Tuesday, the summits will mostly be hidden in fog, intermittent rainfall is anticipated in Tauern and Northern Alps. Snowfall level is 2400 m. During the daytime, conditions and visibility will improve, sunshine is anticipated as of about midday. In the afternoon, no precipitation. Winds will be brisk to strong from thr north. At 2000 m: +3 degrees; at 3000 m: -3 degrees.

On Tuesday night, skies will clear, residual cloud will be tenacious only in a few places.

On Wednesday, good visibility, sunny weather barring a few residual clouds. Brisk northerly winds can be an irritation. Slight rise in temperature: at 2000 m, from 2 to 6 degrees; at 3000 m, from -2 to +1 degree.

Short Term Development

Daytime danger curve on Wednesday and Thursday. Favourable conditions, with melt-freeze crust and corn snow, providing you depart early.
