Heraldo de Madrid - Brazil cyclone death toll rises to 31

The storms, which started Monday, left whole neighborhoods submerged in flood waters in the southern state of Rio Grande do Sul, forcing some residents to climb onto their roofs and wait to be rescued, officials said.

It is the latest in a series of deadly weather disasters to hit Brazil, which experts say are likely being made worse by climate change.

"Unfortunately, I received confirmation of four more deaths," said Governor Eduardo Leite, bringing the total death toll from the disaster to 31.

"There are still a lot of families stranded on the roofs of their houses," he said earlier, before a flyover of flood-hit areas. "There are thousands of people who still need to be rescued."

The governor, who declared a state of emergency, called it the deadliest weather disaster ever to hit Rio Grande do Sul, as hundreds of rescue workers, police and volunteers continued efforts to reach areas cut off by flooding.

More than 5,300 people have been forced from their homes, and more than 52,000 residents and 70 towns affected in all, authorities said.

Leite warned the situation could worsen, with more rain forecast for late Wednesday and into Thursday, Brazil's independence day.

President Luiz Inacio Lula da Silva said he had spoken with the governor and promised his administration's support.

"I reiterated that the federal government is at the disposal of the people of Rio Grande do Sul to face this crisis," Lula wrote on X (formerly Twitter).

- 'Nothing left' -

Communications Minister Paulo Pimenta, who joined the governor on his flyover of the disaster zone, said the federal government would request more aircraft to help in the rescue effort, in addition to four helicopters it sent Tuesday.

"It's a devastating scene," he wrote on X after touring the area.

The floodwaters submerged most of the town of Mucum, population 5,000, where 15 bodies were found.

Local media said authorities there and in the neighboring town of Roca Sales had to resort to using a commercial refrigerator truck to transport victims' bodies.

"It's frightening," Roca Sales Mayor Amilton Fontana told news site A Hora.

"The storm destroyed everything. There's nothing left in Roca Sales today."

The dead included a 50-year-old woman in the town of Lajeado who was being lifted to safety by a rescue worker when the cable holding her broke, plunging her into a flood-swollen river.

A couple in the town of Ibiraiaras was killed when their car was swept away by the current as they tried to cross a bridge.

In addition to the likely impact of climate change, unchecked urbanization and irregular housing built on hillsides are also making weather disasters deadlier in Brazil, experts say.

In June, another cyclone left 13 dead in Rio Grande do Sul and forced thousands of people from their homes.

And in February, 65 people died in landslides caused by record flooding in the southeastern resort town of Sao Sebastiao, on the coast of Sao Paulo state.

An estimated 9.5 million of Brazil's 203 million people live in areas at high risk of flooding or landslides.
