Brazil flood death toll tops 500

Rescuers are searching through layers of mud for survivors and bodies after heavy rains caused landslides and torrents to slice through three towns near Rio de Janeiro, killing at least 500 people.

Walls of thick, muddy gunge cascaded past apartment blocks in several towns, flowing into single-storey homes and overturning cars as they surged down the hills sweeping along everything in their path.

Freakish storms early Wednesday (local time) in the mountainous area just north of Rio de Janeiro dumped the equivalent of a month's rain in just a few hours, sending mudslides slicing through towns and hamlets, destroying homes, roads and bridges and knocking out telephone and power lines.
Local officials and media in the worst affected towns of Novo Friburgo, Teresopolis and Petropolis put the death toll at 432.

President Dilma Rousseff, clad in black rubber boots, walked the mud-covered cobblestone streets of Novo Friburgo, where 201 deaths were recorded.

The death toll was expected to rise further as rescuers arrived in remote hamlets, many cut off to all but helicopter access.

Tropical rains, common at this time of year, intensified as a cold front moved in, unleashing the tragedy before dawn, while families slept.

"In eight hours... it rained as much as for the entire month," said Paulo Canedo, a hydrologist at the Federal University of Rio de Janeiro.

The deluge "caused avalanches of rocks and soil that carried everything down with them, picking up houses," he said.

As weather forecasters warned of more rain in the hours and days ahead, rescuers aided by desperate residents clawed through rubble and mud looking for survivors or bodies.

GloboNews television said 175 people had died in Teresopolis, while officials in Petropolis counted 39 dead.

Another 17 bodies were discovered Thursday in a village called Sumidouro.

Churches and police stations were turned into makeshift morgues, the smell of decomposing corpses heavy in the warm air. Thousands of survivors took refuge in shelters.

But among the despair were a few triumphs.

The scenes of crumbled towns and the stench of death transformed the Serrana region, a popular historical getaway for wealthy Rio residents seeking cooler temperatures.

The disaster also provided the first big test for Ms Rousseff, who only took power on January 1.

Her government has released hundreds of millions of dollars in initial emergency aid and sent seven tons of medical supplies.

The last major natural disaster in Brazil was in March 1967, when mudslides killed 300 people in a coastal town called Caraguatatuba, Brazilian media said.

By way of comparison, Brazil recorded 473 deaths for all of last year from heavy rains.
