Volkswacht Bodensee - Storm Boris wreaks havoc across eastern and central Europe

Since Thursday, swathes of Austria, the Czech Republic, Hungary, Romania and Slovakia have been hit by high winds and unusually fierce rains.

"We are again facing the effects of climate change, which are increasingly present on the European continent, with dramatic consequences," said Romanian President Klaus Iohannis.

"We must continue to strengthen our capacity to anticipate extreme weather events."

In Romania, four bodies were discovered in the worst affected region, Galati in the southeast, where 5,000 homes were damaged.

Hundreds of people have been rescued across 19 parts of the country, rescue services said, releasing a video of flooded homes in a village by the Danube river.

"This is a catastrophe of epic proportions," said Emil Dragomir, mayor of Slobozia Conachi village in Galati, where he said 700 homes had been flooded.

Prime Minister Marcel Ciolacu was expected to visit the area later, while President Iohannis sent his "condolences to grieving families".

Almost 50,000 homes were without electricity on Saturday, Czech power company CEZ said, and a hospital in the southeastern city of Brno was evacuated on Saturday morning.

"The ground is now saturated so all the rainwater is going to stay on the surface," Environment Minister Petr Hladik said on X, formerly Twitter.

Residents are being offered free bags of sand to shore up their homes.

- 'Peak is yet to come' -

Neighbouring Slovakia has declared a state of emergency in the capital, Bratislava.

Meanwhile in Poland, the government warned the situation would be the most difficult in the southwest going into Saturday afternoon and evening.

Authorities have shut the Golkowice border crossing with the Czech Republic after a river flooded its banks, closed several roads and halted trains on the line linking Prudnik to Nysa.

Austria registered winds of 146 kilometres (91 miles) an hour in the south.

Four thousand homes in the Styrie region are without power and the "peak is yet to come", Chancellor Karl Nehammer warned.

In mountainous areas of the west, snow halted traffic and rescue services were searching for a man reported missing after an avalanche.

Some areas of the Tyrol were blanketed by up to a metre (three feet) of snow -- an exceptional situation for mid-September, which saw temperatures of up to 30 degrees Celsius (86 degrees Fahrenheit) last week.
