Donald Tusk's chief of staff estimated that a total of 2.39 million people had been affected by the state of natural disaster introduced in 749 Polish cities and towns. Of those, tens of thousands were directly affected by floodwater.
"Currently, this number stands at 57,000," Grabiec said at an emergency response meeting, adding that the data was preliminary.
Abnormally strong rains caused rivers to overflow their banks, killing at least 20 people and prompting the evacuation of 6,544 in southern Poland. As of now, 11,502 single-family houses and apartment blocks, 6,033 household facilities, and 724 public facilities, such as schools, roads, and bridges, have been damaged or inundated, Grabiec estimated.
Over the past few days, Storm Boris has been raging across Central Europe, causing heavy rainfall and making rivers, particularly the Danube, burst their banks. Poland, the Czech Republic, Slovakia, and the Alpine regions of southern Germany and Austria were hit the hardest.
