Locals spoke of their shock at the extreme weather. Roberto De Angelis told broadcaster BR24: "I've never experienced anything like it before."

In Bavaria, winds of up to 120km/h were recorded, according to the German Weather Service (DWD).

Several car windows were broken by the hailstones. Meanwhile, houses were submerged in water as torrential rain fell.

Emergency teams were called out on 550 operations in Munich alone, DPA reported.

According to rail operator Deutsche Bahn, fallen trees on the tracks between Landshut and Munich caused restrictions to rail traffic, however, trains were able to detour.

There were some delays in freight traffic between Berlin and Dresden.

Eastern Germany also hit by storms

The east German state of Saxony was also severely affected by the storms. In the south of the region, 30 to 50 litres of rain fell per hour, the DWD said. The weather service also registered hailstones with a diameter of up to four centimetres.

The police reported several flooded streets in the Erzgebirgskreis. The responsible police department in Chemnitz reported that these roads were not passable.

The DWD said the situation was better in parts of northern Germany. In the districts of Oldenburg and Bremen, however, there was also heavy rain.

In North Rhine-Westphalia it was rather quiet compared to the east and south. But in Mönchengladbach there was localized flooding; streets overflowed with water and cellars were flooded due to the rain.

Meanwhile, a large forest fire on a former military training area near Jüterbog in Brandenburg was extinguished.  Task forces had been fighting the fire for several days.
