More heavy rain is expected to pummel Brazil, as the South American nation grapples with the deadly fallout of last week’s extreme weather, which submerged whole neighborhoods.

Ednews informs via CNN that the heavy rains and floods have killed at least 107 people in Brazil’s Rio Grande do Sul since last week, the state’s civil defense agency said Thursday morning.

Some 1,476,000 people have been affected, according to the civil defense, with at least 754 people left injured and about 164,00 displaced. At least 134 people are still missing.

The catastrophic floods have been accompanied by social upheaval, with least 47 people arrested for looting and other crimes amid the chaos. Six of those arrested are suspected of committing sexual abuse in shelters for people whose homes were impacted by the floods, according to state-run media Agencia Brasil.

But officials are urging those who have been rescued from the floods not to return to their homes, warning that more rain is in the forecast.

From Friday to Sunday, intense rainfall is expected to hit again between the east and center-north of Rio Grande do Sul, with some areas expecting 100 mm (nearly 4 inches), the national meteorology institute INMET said Wednesday night.
