Heavy rains flooded huge parts of northern Europe over the weekend as "freak thunderstorms" ravaged the continent and left as many as five people dead.
In Poland, one man was struck dead by lightning. In Germany, two men were presumed dead after being sucked into a flooded underpass, and two others perished in flood-related accidents. Dozens were injured in lightning strikes at a children's birthday party in Paris and a soccer match in Germany.
The French Open canceled games on Tuesday -- its first complete washout in 16 years, according to France24. Auto giant Audi halted production at one of its major factories in southwestern Germany.
The storm systems were prompted by a warm plume of air that extended north from Africa into Europe, according to the U.K.'s Met Office.
The devastation caused by the flooding shows the vulnerabilities that even wealthy countries face as global warming causes the climate to change and weather to become more extreme.
"We cannot predict climate on a local scale 10 years ahead or even further, but we can put a lot more effort on extracting the information on what could be happening in that far-away abstract future by looking at the extremes that happen today," Bart van den Hurk, a doctor at the Royal Netherlands Meteorological Institute, said in a report published last week by the European Commission.
A study released in March 2014 found that the frequency of severe flooding across Europe is expected to double by 2050. The annual economic costs from that flood will go up nearly fivefold, the study found.
There are no clear estimates yet of the cost of the damage caused by this round of flooding. But these photos show some of the devastation so far:
