Four bodies were found floating in homes in France and Germany Wednesday in flash floods that left water lapping at the doors of one of the Loire Valley's most famous chateaux. Heavy rains lashing parts of France, Germany and Austria cut roads, stranded people on rooftops and forced schools to close their doors, and French weather forecasters warned of more to come on June 2, 2016. / AFP PHOTO / Christof StacheCHRISTOF STACHE/AFP/Getty Images
