No letup yet for flood-battered southern Brazil

In total, 384 cities, towns and villages in Brazil have been hit, many of which remain cut off from the world
In total, 384 cities, towns and villages in Brazil have been hit, many of which remain cut off from the world.

The rains may have abated, but floodwaters continued their assault on southern Brazil Monday, with hundreds of municipalities in ruins amid fears that food and drinking water may soon run out.

Since the unprecedented deluge started last week, at least 85 people have died and more than 150,000 were ejected from their homes by floods and mudslides in Rio Grande do Sul state, authorities said.

The search is becoming ever more desperate for 134 people reported missing among the devastation that also left 339 people injured.

The disaster, which experts and the government have linked to , has left the state resembling "a scene out of a war," the state's governor Eduardo Leite said Sunday.

In total, 385 cities, towns and villages have been hit, many of which remain cut off from the world—without access to drinking water or electricity or any means of calling for help.

In Porto Alegre, the state capital with 1.4 million inhabitants, many suburbs remained under water even as the sun shone Monday.

"Last night, the water came up to the corner and had stabilized. Today, we woke up and it was outside my house and rising," Neucir Carmo, a 62-year-old resident of the Floresta neighborhood, told AFP.

Some regions had received the equivalent of a third of average annual rainfall in just a few days

"We don't know how high it will go."

The Guaiba River, which flows through the mega-city of high-rise buildings and wide streets, reached a record high level of 5.3 meters (17.4 feet) Sunday—well above the historic peak of 4.76 meters that accompanied devastating floods in 1941.

By Monday morning, the level had receded slightly, to 5.27 meters.

The MetSul meteorological agency said on its website that some parts of Porto Alegre, the wider metropolitan region and valley settlements "will be uninhabitable for weeks to months."

Some regions had received the equivalent of a third of average annual rainfall in just a few days, it said.

"The scenario is complicated because the weather conditions, excellent today, will not continue like this. On Wednesday, the areas affected by flooding in Greater Porto Alegre and the valleys may experience rain again," said MetSul.

Climate change meets El Niño

The deluge, which started a week ago, has swept away bridges and dozens of roads, complicating relief efforts that have to rely instead on helicopters and boats.

Some 14,000 soldiers are aiding search and rescue professionals and volunteers working against the clock as concerns grow about supplies of food, potable water and other essentials.

Donations of food and medicine poured in from around the country, and Good Samaritans have contributed the equivalent of about $7.6 million to a rescue fund.

The country's star footballers have mobilized in the drive to raise funds, with players like Vinicius Jr, Neymar and Ronaldinho adding their faces to a call by the Brazilian Football Confederation for donations for victims.

At the state's civil defense logistics center in Porto Alegre, mountains of donations were awaiting distribution as flew critical medical supplies to flooded areas.

Authorities said there were more than 47,000 people in public shelters and field hospitals set up after hospitals and clinics were flooded.

Classes in Porto Alegre have been suspended until Wednesday, and schools are being used as makeshift shelters, officials said.

President Luiz Inacio Lula da Silva visited the region Sunday for the second time in days, promising the federal government would provide "all the necessary" resources needed for the reconstruction of the state, home to 11 million inhabitants.

South America's largest country has recently experienced a string of extreme weather events, including a cyclone in September that killed at least 31 people in the same region.

Brazilian climatologist Francisco Eliseu Aquino told AFP the flooding was the consequence of a "disastrous cocktail" of climate change and the El Niño meteorological phenomenon.

According to MetSul, "the biggest concern is the indications... that between the 10th and 15th of May there would be a new episode of instability with a risk of excessive rain in Rio Grande do Sul."

These would once again affect Porto Alegre and the Guaiba River, it said.
