The German Weather Service (DWD) is warning of possible local thunderstorms with heavy rain in a strip from southwest Germany to the middle of the country. The DWD in Offenbach announced on Thursday that hail showers and squalls were also possible locally from Thursday afternoon until Friday night. In the afternoon the first severe thunderstorms with strong thunderstorms moved through North Rhine-Westphalia.

The German Weather Service registered the first focal points on Thursday afternoon in the Eifel, the Bergisches Land as well as in Cologne and Düsseldorf, according to the German Weather Service in Essen. In the afternoon in Dahlem in the Eifel, 36 liters per square meter were measured within one hour, and in Wuppertal there were 26 liters per hour per square meter.

The consequences on Thursday were initially not too serious for NRW. A spokesman for the Cologne fire department said early in the evening that the first of two expected thunderstorms had now passed and that there was no particular emergency response.

The greatest danger comes from heavy rain, which can sometimes last for several hours. Precipitation of up to 50 liters per square meter is possible within a few hours. The DWD cited a line that currently extends from North Rhine-Westphalia to Bavaria and only slowly moves northeastwards, which separates moist and cool air in the southwest from significantly warmer air in the rest of Germany. Thunderstorms form along this low-pressure channel – where exactly cannot be determined in advance.

According to meteorologists, the thunderstorms will subside over the course of Friday, and in the west there could be rainfall of up to 35 liters per square meter within six hours until the morning. As Friday progressed, they announced thunderstorms with heavy rain, but expected slightly lower amounts of precipitation, stormy gusts and hail from Lusatia across eastern Brandenburg and Mecklenburg-Western Pomerania to Schleswig-Holstein.
