The crest of the flood-swollen Danube River surged toward the Hungarian
capital of Budapest on Friday, while communities along the Elbe in
Germany braced for high water as the river churned toward the North Sea.
Elsewhere in central Europe, communities were beginning to count the cost of devastating floods that have hit Germany, Austria, Switzerland, Hungary, Slovakia, Poland and the Czech Republic.
At least 19 people have died over the past week, and experts say the economic damage in Germany alone could top 11 billion euros ($14.6 billion).
The Danube's crest left Austria on Friday and entered Hungary, where Prime Minister Viktor Orban warned that water levels were above the all-time highs.
"It is now certain that we will face the largest-ever flood on the Danube, so we must be prepared for the worst," Orban said Gyor, a western city on the Danube.
The crest was expected to reach Budapest on Monday, and Mayor Istvan Tarlos said in a worst-case scenario up to 55,000 people may need to be evacuated. But he was confident that only the lowest-lying areas of the city would be exposed to the Danube's surge.
Tarlos said the Danube was expected to rise to around 8.95 meters (31 feet) in the downtown area, while the walls along the river and temporary defenses would be able to keep out waters up to 9.3 meters (30 feet, 6 inches).
In neighboring Slovakia, the situation was critical in the border city of Komarno where the Danube was still rising and was expected to do so till Saturday. Rescuers, soldiers and volunteers have been filling sand bags to reinforce protective barriers.
In the Czech Republic, the government's central crisis committee ordered local authorities to leave all flood protection measures in place because meteorologists have forecast possible heavy rains for the next few days and the situation could get worse again.
"The flooding is not over yet," Czech Prime Minister Petr Necas.
In Germany, meanwhile, water levels were stabilizing in the south and east, even as the crest of the Elbe rolled northward.
