Rising floodwaters, which have claimed at least a dozen lives in central Europe, are continuing to wreak havoc, with rescuers struggling to reach the worst-hit areas.
Rivers have been rising fast as a result of heavy rain and melting snow, with officials warning further heavy rain is expected this week.
In Hungary, the River Danube has reached record levels. Deaths across the region included an 18-month-old Austrian toddler.
The Danube was expected to peak at 8.65m (28 feet) in Budapest, topping its previous record of 8.48m in 2002.
The Hungarian government has deployed more than 10,000 police, soldiers and rescuers to some of the country's worst-hit areas.
Around 25,000 people, half of them volunteers, struggled to maintain flood defences before reinforcements were called in.
Eight cities in Germany were affected on Tuesday with more than 1,300 people evacuated from homes.
Around 1,000 people have been evacuated from homes around the east German city of Dresden, which was devastated by flooding in 2002.
Floodwaters continue to threaten residents in the Czech Republic, particularly in the north and south-east, with officials warning floods will last at least another week.
