Wet loose-snow avalanches expected. Weak layers in old snow require caution, esp. in southern regions
Due to solar radiation, increasingly frequent generally small-sized wet loose-snow avalanches are anticipated, esp. on extremely steep sunny slopes and in starting zones which have not yet discharged. Avalanches are triggerable by persons in the weak old snow, esp. on W/N/E facng slopes above 1800m, releases generally medium-sized. Danger zones are difficult to recognize. Isolated whumpf noises are an indicator of danger. Isolated glide-snow avalanches are possible.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Sunny slopes: Due to low temperatures and low air moisture, a surface crust forms during the nocturnal hours. Solar radiation leads to significantly moister snowpack, esp. on extremely steep slopes. The fresh snow lies atop an unfavorable snowpack on W/N/E facing slopes above 1800m.
Tendency
Wet loose-snow avalanches can trigger in starting zones which have not yet discharged
Danger level
2200m
Avalanche Problem
Persistent weak layer
2200m
Caution: weak layers in old snow.
Isolated avalanches can be triggered in the weak old snowpack be persons, esp. on W/N/E facing slopes. Caution urged in transitions from shallow to deep snow in regions where strong winds are blowing. Isolated whumpf noises are indicators of imminent danger. Older snowdrifts can in isolated cases be triggered esp. on shady slopes above 2200m, releases mostly small-sized. Due to solar radiation, mostly small moist loose-snow avalanches are possible below 2600m, esp on extremely steep sunny slopes. Pay attention to runout zones.
Snowpack
dp.1: deep persistent weak layer
Inside the snowpack are expansively metamorphosed, faceted weak layers, esp. on W/N/E facing slopes above 2200m. The older snowdrift accumulations lie deposited atop soft layers on wind-protected shady slopes. Sunny slopes: due to low temperatures and low air moisture, a melt-freeze crust forms on the surface during the night. Solar radiation will lead to significant moistening of the snowpack.
Tendency
Wet loose-snow avalanches can trigger in starting zones which have not yet discharged
Danger level
Caution: loose-snow avalanches on extremely steep sunny slopes
Due to solar radiation, increasingly frequent generally small-sized wet loose-snow avalanches are anticipated, esp. on extremely steep sunny slopes. Avoid the runout zones! Avalanches are triggerable by persons esp. by large addtional loading on NW/N/NE facing slopes above 2000m, releases mostly small.
Snowpack
Sunny slopes: Due to low temperatures and low air moisture, a surface crust forms during the nighttime hours. Solar radiation will lead to significantly moister snowpack during the daytime, esp. on extremely steep slopes. The fresh snow and drifts lie atop an unfavorable snowpack on NW/N/NE facing slopes above 2000m.
Tendency
Loose-snow avalanches can trigger in zones which have not yet discharged.
