SAO PAULO —

Heavy rains in the southern Brazilian state of Rio Grande do Sul killed 39 people, with 68 more missing, the state civil defense agency said Friday, as record floods devastated cities and forced thousands to leave their homes.

It was the fourth such environmental disaster in a year, following floods in July, September and November 2023 that killed 75 people in total.

The flooding statewide has surpassed that seen during a historic 1941 deluge, according to the Brazilian Geological Service. In some cities, water levels were at their highest since records began nearly 150 years ago, the agency said.

On Thursday, a dam at a hydroelectric plant between the cities of Bento Goncalves and Cotipora partially collapsed and entire cities in the Taquari River valley, like Lajeado and Estrela, were completely overtaken by water. In the town of Feliz, 80 kilometers from the state capital, Porto Alegre, a massively swollen river swept away a bridge that connected it with the neighboring city of Linha Nova.

Operators reported electricity, communications and water cuts across the state. More than 24,000 people had to leave their homes, according to the civil defense agency.

Without internet, telephone service or electricity, residents struggled to provide updates or information to their relatives living in other states. Helicopters flew continually over the cities while stranded families with children awaited rescue on the rooftops.

Isolete Neumann, 58, lives in the city of Lajeado in the Taquari River valley and told The Associated Press she has never before seen what she is seeing now.

"People were making barricades in front of hospitals with sand and gravel. It felt like a horror movie," she said by phone. Some people in her region were so desperate, she added, that they threw themselves into the water currents.

Neumann's neighborhood wasn't inundated but has no running water and she hasn't showered since Tuesday. She said she's collecting rainwater in a basin so she can cook. A clothing store she owns in the city's central area is flooded, she added.

The downpour started Monday and is expected to last at least through Saturday, Marcelo Seluchi, chief meteorologist at the National Center for Monitoring and Alerts of Natural Disasters, told Brazil's public television network Friday.

President Luiz Inácio Lula da Silva acknowledged the flood victims at a press conference on Friday alongside Japan's Prime Minister Fumio Kishida in Brasilia.

"The first words from Minister Fumio Kishida in the meeting we held were of solidarity with the people of the state of Rio Grande do Sul, who are victims by one of the largest floods we have ever known. Never before in the history of Brazil had there been such a quantity of rain in one single location," Lula said.

Weather across South America is affected by the climate phenomenon El Niño, a periodic, naturally occurring event that warms surface waters in the Equatorial Pacific region. In Brazil, El Niño has historically caused droughts in the north and intense rainfall in the south.

This year, the impacts of El Niño have been particularly dramatic, with a historic drought in the Amazon. Scientists say extreme weather is happening more frequently because of human-caused climate change.

Dams strain as water, death toll keep rising in south Brazil

The death toll from floods and mudslides triggered by torrential storms in southern Brazil climbed to 39 on Friday, officials said, as they warned of worse to come.

As the rain kept beating down, rescuers in boats and planes searched for scores of people reported missing among the ruins of collapsed homes, bridges and roads.

Rising water levels in the state of Rio Grande do Sul were straining dams and threatening the metropolis of Porto Alegre with “unprecedented” flooding, authorities warned.

“Forget everything you’ve seen, it’s going to be much worse in the metropolitan region,” Governor Eduardo Leite said Friday as the streets of the state capital, with a population of some 1.5 million, started flooding after days of heavy downpours in the region.

The state’s civil defense department said at least 265 municipalities had suffered storm damage in Rio Grande do Sul since Monday, injuring 74 people and displacing more than 24,000 — a third of whom have been brought to shelters.

At least 68 people were missing, and more than 350,000 have experienced some form of property damage, according to the latest data.

And there was no end in sight, with officials reporting an “emergency situation, presenting a risk of collapse” at four dams in the state.



– ‘Disastrous cocktail’ –



The level of the state’s main Guiaba river, meanwhile, was estimated to have risen 4.2-4.6 meters (about 13.7-15 feet), but could not be measured as the gauges have washed away, the mayor of Porto Alegre said.

As it kept rising, officials raced to reinforced flood protection.

Porto Alegre’s worst recorded flood was in 1941, when the river reached a level of 4.71 meters.

Elsewhere in the state, several cities and towns have been completely cut off from the world in what Governor Leite described as “the worst disaster in the history” of Rio Grande do Sul.

Many communities have been left without access to drinking water, telephone or internet services.

Tens of thousands have no electricity.

President Luiz Inacio Lula da Silva visited the region Thursday, vowing “there will be no lack of human or material resources” in responding to the disaster, which he blamed on climate change.

The central government has sent aircraft, boats and more than 600 soldiers to help clear roads, distribute food, water and mattresses, and set up shelters.

School classes have been suspended state-wide.

“I feel very sorry for all those who live here… I feel pain in my heart,” Maria Luiza, a 51-year-old resident of Sao Sebastiao do Caí, some 40 miles (70 km) from Porto Alegre, told AFP.

In Capela de Santana, north of the state capital, Raul Metzel explained that his neighbors had to abandon their livestock.

“You don’t know if the water will continue to rise or what will happen to the animals, they may soon drown,” he said.

Climatologist Francisco Eliseu Aquino told AFP on Friday the devastating storms were the result of a “disastrous cocktail” of global warming and the El Nino weather phenomenon.

South America’s largest country has recently experienced a string of extreme weather events, including a cyclone in September that claimed at least 31 lives.

Aquino said the region’s particular geography meant it was often confronted by the effects of tropical and polar air masses colliding — but these events have “intensified due to climate change.”

And when they coincide with El Nino, a periodic weather system that warms the tropical Pacific, the atmosphere becomes more unstable, he said.

Extreme flooding hit the state in the last two years at “a level of recurrence not seen in 10,000 years,” said Aquino, who heads the Federal University of Rio Grande do Sul’s geography department.
