After the Downpour, Radiance Emerges
In certain parts of Central Europe, a century's worth of rain is currently pouring down – and the forecast calls for more rain in the upcoming days. However, by the end of the week, the stormy skies will clear up, allowing for the final glorious display of summer.
Tropical Storm Anett, which has been making its way from North Italy through Hungary towards Poland, has levied substantial amounts of rain on eastern Austria, the Czech Republic, and southern Poland. Some areas have received as much as 150 to 250 liters of rain per square meter in just three days, with even higher amounts – up to 300 liters – reported in Lower Austria and the Giant Mountains at the Czech-Polish border. For reference, Berlin typically receives approximately 580 liters of rain per square meter in an entire year.
The excessive rainfall has resulted in severe flooding: water levels in Lower Austria have reached heights not seen since every 30 years in some places, with certain areas even experiencing 100-year floods. Further heavy rainfall within the next 48 hours could exacerbate the situation further. By Tuesday morning, Lower Austria may receive an additional 100 to 150 liters of rain, while the Czech-Polish border could expect 50 to 80 liters.
However, the rain in the Alps has primarily fallen as snow, with snow levels even reaching some valley regions such as Mittenwald, Kreuth, and Ruhpolding-Glashütte. Currently, there is one meter of snow on the Zugspitze and 77 centimeters on the Nebelhorn in the Allgäu – both unusually high amounts for mid-September. As of tomorrow, the snow line will rise above 2,000 meters, and the resulting snowmelt could maintain high water levels for an extended period.
Conversely, by Tuesday, high pressure will significantly increase, bringing in pleasant, warm late-summer weather that we can refer to as "Indian summer" starting from mid-September. There will be another package of local showers on Thursday, but it is expected to be brief.
Monday: More rain in Southern Bavaria
Heavy, persistent rainfall is occurring south of the Danube. The flooding situation in Passau remains critical. Meanwhile, in Northern Bavaria and the East, the weather begins cloudy and wet, but the rain will gradually subside during the day and move towards the Ore Mountains. Elsewhere in the country, rain showers will alternate with brief periods of sunshine, with the North Sea coast being the most pleasant. Temperatures will range from 15 to 20°C, with 8 to 13°C in the Southeast.
Tuesday: Fading rain showers in the South
Clouds and intermittent rain showers will cover Baden-Württemberg and Bavaria, which will dissipate by evening. The center and North will experience warmer, drier weather. Temperatures will noticeably increase, with 13 to 20°C in the South and 21 to 26°C in the North, with the highest temperatures found in Berlin.
Wednesday: Lots of sunshine
Sunshine will dominate the country, with occasional clouds the only interruption. With a strong east wind, temperatures will range from 20 to 26°C, with values reaching 17°C in the Alpine foothills. Even the Zugspitze's snow will start melting at warmer temperatures.
Thursday: Momentarily unsettled
A small cold air trough will travel east to west across the country, bringing some unsettled weather, particularly in the mountains. Temperatures will remain at 20 to 25°C, with 18°C at the Alps.
Friday and Weekend: Beautiful Summer Weather Bids Farewell
Expect plenty of sunshine each day from Friday to Sunday, with morning fog patches disappearing quickly and thick clouds forming only over the mountains later in the afternoon – rain, however, is unlikely to occur. Temperatures will remain between 20 and 25 degrees Celsius. On Sunday, the calendar summer will come to an end, and from Monday onwards, days will be shorter than the nights.
The relentless rain from Tropical Storm Anett has worsened the weather situation in certain areas, bringing an abnormal amount of precipitation. As of Monday, Southern Bavaria is also experiencing heavy rainfall, adding to the flooding concerns.
