Brazil is bracing for new storms just days after a devastating cyclone killed at least 41 people in the country’s south, officials said.

Twenty-five people remain missing after an extratropical cyclone this week hit the state of Rio Grande do Sul, which is also the target of the new weather system.

Late Thursday, “a cold front will advance along the border with Uruguay and will reinforce instabilities in the southern regions of the state, expanding to northern areas between Thursday night and early Friday”, according to a warning from the state Government, citing a meteorologist.

Flooding from the earlier storm submerged whole neighborhoods in Rio Grande do Sol, forcing many people to climb onto roofs while awaiting rescue.

More than 10,500 people were forced to leave their homes in 83 municipalities hit by the cyclone.
