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.

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 374 people left injured and about 164,00 displaced.

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.

“It is important to highlight that the predicted volumes of rain may cause new disruptions in areas already affected previously,” a statement from INMET read.

The record rainfall hitting the region has been linked to El Niño, a natural climate phenomenon that warms waters in the Pacific and tends to bring heavy rainfall to southern Brazil. Long-term global warming caused primarily by humans burning fossil fuels has also exacerbated extreme weather in the region.

With many of southern Brazil’s communications downed by the storms, SpaceX CEO Elon Musk also announced in a post on X Thursday that Starlink will donate 1,000 internet terminals to emergency responders in the region.

The latest storms have also flooded parts of neighboring Uruguay, leaving some 1,347 people displaced and thousands more without electricity, the national emergency system said Wednesday night.
