The Polish Ministry of Defence has posted on X that a bridge has been destroyed in Stronie Slaskie and a “large wave of water is passing through the town.”

“Soldiers supporting the local population are cut off from their land route back. Many residents have to be evacuated from the roofs of their homes,” the ministry said.

“An Mi-17 helicopter was sent to the site to assist with the evacuation,” it said.

Torrential rainfall has also breached a dam releasing a powerful torrent of water that has apparently destroyed a least one house, the Institute of Meteorology and Water Management (IMGW) has said.

“The dam in Sronie Slaskie has been breached and the water is flowing down the Biala Ladecka river towards the Nysa Klodzka catchment area,” the IMGW posted on the X platform.

In a separate post the IMGW reposted a video from Polish Radio that appears to show a house being swept away by the water in the town in Lower Silesia.

An IMGW spokesman told the state news agency (PAP) that a side wall of the dam has been damaged, adding the water “is a huge force that destroys buildings”. “This is no longer a drama, it is a tragedy,” Grzegorz Walijewski said.

The residents of Stronie Slaskie are being evacuated, PAP reported.

Rescuers in Romania have announced a fifth person has died in the country, according to the AFP news agency.

The rescuers said in a statement that the person died in the region of Galati in the south-east of Romania - the same region where four people were killed on Saturday during floods.

As we've been reporting, Storm Boris is causing flooding in countries in central and eastern Europe today.

A state of emergency has been declared in Slovakia's capital, Bratislava, the Austrian province surrounding Vienna has been declared a disaster area, and there are rising water levels in southern Germany.

Officials have forecast that the Danube River in Hungary's capital Budapest could rise to near record levels, and the Budapest Times, external has reported that the city's mayor has issued a third-degree flood alert along flood protection sections of the river.

At a news briefing following emergency talks, Prime Minister Petr Fiala and Interior Minister Vit Rakusan called on people to heed calls to evacuate when told to do so by their local mayors - otherwise, their lives could be in danger.

Mr Rakusan said all efforts now would be concentrating on preventing any loss of life.

Several thousand people, mostly in towns across the eastern half of the country, have been evacuated. Around 200,000 were left without power on Sunday morning.

No deaths have yet been confirmed, but four people remain missing. Three people were last seen in a car which disappeared into a river in North Moravia, and one man was swept into a flooded stream in South Moravia.

The authorities have repeated pleas for people to take the emergency seriously.

Several dozen police and firefighters in Prague were called to rescue a man who went swimming in the flooded Vltava on Sunday morning. He was carried two kilometres downstream before ending up in reeds.

On Saturday, police in North Moravia were called after three men were spotted on paddleboards on the flooded River Odra. The three - described as professional paddleboard instructors - were ordered out of the river.

Heavy flooding has hit towns in the northern Czech Republic with rivers overflowing and torrents of water running down streets.

In the town of Lipova Lazne footage shows businesses and homes being destroyed.

Authorities are on high alert as more rain is expected.

Prime Minister Donald Tusk confirmed the first drowning death in Poland, although police have been unable to reach the village where it occurred because it has been cut off.

In the district of Kłodzko near the Czech border, more than 1,600 people have been evacuated from their homes

It's one of the worst affected areas - water has reached a depth of 1.5m (4.9 ft) in some parts of the town.

Around 17,000 people in the Kłodzko area alone are without power, and internet and mobile telephone connections are down. Tusk has authorised the use of Starlink satellite technology for the internet.

A Blackhawk helicopter has been deployed to the area to airlift people stranded on rooftops.

North Moravia and Silesia remain the hardest hit regions of the Czech Republic, with the Silesian spa town of Jesenik completely cut off by the floods.

Jesenik mayor Zdenka Blistanova told Czech Radio only three streets in the mountainous town of 11,000 people remained above water.

Those who had refused calls by the authorities to evacuate were now stranded, she said, as the fire brigade could no longer reach them.

The weather conditions were too severe for helicopters belonging to the police and regional authority, she told Czech Radio, adding that she was waiting for help to arrive from the army.

In the meantime, those left in the town had been told to move to the upper floors of their homes.

A video posted on X from the town showed some houses being swept into the river by the torrent.

Storm Boris has already brought extreme amounts of rain across central and eastern Europe, with more torrential downpours in the forecast through until at least the end of Monday. It has been described as a 1 in 50 year event by the Ministry of the Environment of the Czech Republic.

Some of the highest rainfall totals so far have been in the Czech Republic. At Lysa Hora in the mountains in the west of the country, 288mm of rain has fallen since Thursday. This is around three months’ worth of rain in just three days.

The storm has been so devastating for two reasons.

Firstly, the positioning of the storm has been drawing in colder air from the north to mix with moisture drawn up from the unusually warm waters of the Mediterranean and the Black Sea.

Secondly - the low pressure has been very slow moving over the same areas. It’s been stuck in a ‘blocked weather pattern’, meaning the storm is cut-off and trapped between high pressure to the west and the east.
