Days of heavy rain in Brazil's Rio Grande do Sul have caused the worst floods the country’s southernmost state has seen in at least 80 years — and the sheer impact of it can be seen in new drone footage.
Since 2 May, 417 of the state’s 497 cities have been inundated, as a hydroelectric dam situated between between Cotiporã and Bento Gonçalves collapsed, and lakes and rivers overflowed.
The floods have displaced over 150,000 people and killed at least 100, while hundreds of people are still missing or awaiting evacuation and millions have been left without access to water and electricity.
Brazil's National Centre for Monitoring and Warning of Natural Disasters (CEMADEN) has said Rio Grande so Sul is at "high risk" of further flooding, as heavy rainfall is projected to continue.
