Poland has been hit by its second serious round of flooding in three weeks.
Thousands of people have been told to evacuate their homes in the south of the country, although local officials say many are reluctant to do so and are not taking the danger seriously.
Heavy rain has again broken the banks of the Vistula river. Massive floods last month left 20 people dead across Poland.
To the south in Slovakia, several rivers have spilled out into towns and villages.
Vigilant residents near Kosice prevented a potential disaster by noticing that a landslip had led soil to spill onto a railway line. Authorities were able to close the line between Kosice and the Slovak capital, Bratislava.
And in Hungary, the prime minister has called up a 12,000-strong force made up of policemen, soldiers and volunteer prison inmates to reinforce the banks of the Hernad river.
It rained almost constantly in Hungary throughout May; the monthly rainfall reached around 22 centimetres, or the average amount for the whole year.
