The scenarios drafted by hydrologists valid as of yesterday have turned out to be underestimated. Road works on the tramway tracks at the intersection of ul. Milenijna and Popowicka, which included the reconnection of a sewer, are completed. This means that tram service to Kozanów will be resumed from 2nd April. Tram line 31 will run again on its route via Kozanów to the Tarczyński Arena (Królewiecka) terminus. Because of the limited capacity of the tramway tracks at ul. Dokerska and Gwarecka, which will be used temporarily by tram lines 3, 10 and 20, tram line 32 will continue to be suspended. To maintain the adequate number of seats after the suspension of tram line 32, tram line 31 will continue to run at the following intervals: After the reopening of the tramway to Kozanów, temporary bus line 731 will be withdrawn.

Polish prime minister Donald Tusk says the flooding is the worst Poland has ever experienced, with several parts of the country underwater. Water levels are beginning to go down in the south of the country but rivers are now taking the floodwaters north. The south-western Polish city of Wroclaw has been partially flooded as a dike on the Sleza river, a tributary to the Oder, broke and sent floodwaters into the Kozanow neighbourhood. The floods sweeping across the country have caused damage estimated at more than 2.4 billion euros ($3.6 billion). In the capital Warsaw, authorities appealed to residents in low-lying areas near the Vistula River to be ready to evacuate if necessary. The river has reached 7.8 metres, a level not seen in 60 years. With the waters not expected to begin dropping before Tuesday, authorities are worried waterlogged dikes on the Vistula may not hold. The Vistula winds in an s-shape across Poland for 1,050 kilometres from the mountainous south to the Baltic Sea in the north. Prime minister Donald Tusk presented parliament on Friday with a report on the floods, saying their scale was "without precedent in the past 160 years". "The situation in the River Vistula basin is much worse than in the last major floods of 1997," he said. Mr Tusk's chief aide, Michal Boni, says if the cost of flood damage is found to have exceeded 2.1 billion euros, Poland can formally request help from a European Union crisis fund, which would unlock 100 million euros of EU money. At Poland's request, the 27-nation EU formally kicked off an emergency operation on Wednesday. Among the individual EU member states who have so far sent rescuers and equipment were France, Germany, the Baltic nations of Lithuania, Latvia and Estonia, and Poland's neighbour the Czech Republic, which has also been hit by floods. Mr Boni says 23,000 people have been evacuated from flood-hit regions, out of a total affected population of 100,000.
