Authorities are on high alert due to rising river levels and the expectation of more rainfall in the next few days.
On Sunday, two additional people were killed in Romania, one person was confirmed to have drowned in southwest Poland, and a firefighter fighting flooding in Austria also passed away.
The deaths of three women and one male were also found on Saturday in the Galati county of eastern Romania, where around 25,000 people were left without electricity and 5,000 homes were destroyed.
Over 160 liters (42 gallons) of rain poured per square meter in certain places.
Klaus Iohannis, the president of Romania, expressed his sympathies to the relatives of the victims, saying: “We must continue to do it.
Once more, the effects of climate change are a problem for us; they are becoming more and more prevalent across the European continent and are having serious negative repercussions on people.”
Climate change brought on by humans has made the atmosphere hotter, which increases its capacity to hold water and produces heavier rainfall.
The majority of the nation’s flooding occurred in the north of the Czech Republic, where up to 450mm of rain fell since Wednesday night, leaving more than a quarter of a million houses without electricity, according to the Czech Weather Institute.
Still, the majority of the nation has been impacted, with the highest level of flood alert being issued for about 100 locations.
