Landslides Devastate Brazilian City

On Tuesday, the state fire department said, more than 10 inches (25.8 centimeters) of rain fell on Petrópolis in just three hours. That’s almost as much rain as the amount that fell during the entire previous month, making it the most intense rain the city has seen since 1932, according to Reuters. Weather forecasters say that more rain will come to the region later this week.

“What we saw was a really extreme event,” Cássia de Castro Martins Ferreira, a researcher at the Federal University of Juiz de Fora, told the New York Times. “It didn’t rain—it was an extraordinary amount of water that poured down.”

Extreme precipitation has become more common in our changing climate, since warmer air can hold more moisture. The Intergovernmental Panel on Climate Change’s bombshell report last year found that, across the world, heavy rains have become 30% more frequent as the planet has warmed, and these storms hold on average 7% more water.

Dramatic footage posted on social media showed torrents of brown water charging down steep streets and churning through avenues, carrying trees, cars and other debris along with it. A wave of water was also filmed destroying buildings as it crashed down a hill.

“The situation is almost like war,” Rio de Janeiro Governor Claudio Castro told reporters at the site, according to Reuters. “Cars hanging from poles, cars overturned, lots of mud and water still.”

Petrópolis is known as Brazil’s “Imperial City,” built in the mid-19th century by Emperor Pedro II, and is filled with classic European-style architecture set among lush parks and sheer mountains. However, the region’s geography makes it vulnerable to storms as warmer air collides with cold temperatures in the mountains, while the city’s rapid expansion higher into the hills has cleared out forests and land that would usually protect from disastrous flooding. In 2011, landslides and rains killed more than 900 people in the larger Rio de Janeiro area, including in Petrópolis.

“I lost my niece and her five-year-old daughter, who we still haven’t found,” a resident identified only as Hilda told Reuters. “We did not expect this tragedy. Our city is over.”
