WHY? - danger patterns (dp):
Moderate danger widespread above 2000m
Avalanche danger in Tirol’s backcountry tourng regions is moderate over widespread areas above 2000m. Danger zones for dry-snow slab avalanches are found on very steep, shady slopes and in ridgeline terrain above 2400m. Avalanches can be triggered primarily by large additional loading. Below 2400m the snowpack loses its firmness by late morning. On sun-drenched slopes wet-snow avalanches can then trigger naturally, such slopes require special caution.
The snowpack on shady slopes up to 2200m, on sunny slopes up to 3000m is thoroughly wet. Following a night of clear skies the snowpack consolidated somewhat, forming a crust capable of bearing loads. During the day it will again forfeit that firmness due to warmth and radiation, losing its stability.
Alpine Weather Forecast (ZAMG-Weather Service Innsbruck)
Weather: at the rim of the currently reigning high-pressure front, Tirol will have moderately moist and temporarily cool air masses driven its way from the northeast today. Their effects are more clouds than yesterday. As of tomorrow, Monday, this high will land right over the Alps. Stable, mild and dry springlike weather will be the result. Mountain weather today: somewhat variable conditions, quite windy and slightly cooler. Clouds will come and go variably, sometimes impeding visibility. Fog will also be evident south of the Main Alpine Ridge. In the East Tirolean mountains and Dolomites, light showers are possible this afternoon, snowfall level at 1800-2000m. At 2000m: cooling from +3 to -2 degrees; at 3000m: from -2 to -6 degrees. Moderate NE winds, brisker in some places.
