At least 22 people died in southern Brazil due to a fierce storm that caused floods in several cities, authorities said.

Rio Grande do Sul Gov. Eduardo Leite said the death toll is the state’s highest due to a climate event. He said about 60 cities had been battered by the storm, which was classified as an extratropical cyclone.

Leite said 15 of the deaths occurred in one house in Mucum, a city of about 50,000 residents. The Rio Grande do Sul state government said it had recorded 1,650 people made homeless since Monday night.
