No fewer than 29 people have been confirmed dead in
storms that reigned for four consecutive days.
The storm heralded intense rainfall, floods, and mudslides in Rio Grande do Sulworst.
Reports say more than 60 are missing, Governor Eduardo Leite said.
“Unfortunately, we know that these numbers will rise,” said Leite.
He described the storms as the worst natural disaster in the state’s history.
Brazilian President Luiz Inacio Lula da Silva visited Santa Maria, one of the state’s worst-hit cities, and met with Leite on Thursday.
Lula offered federal funding and aid to address the emergency in the state bordering Uruguay and Argentina.
“There will be no shortage of help from the federal government to take care of health, no shortage of money to take care of transportation and food, everything that is within reach.
“Whether through ministers, civil society, or our military, we’ll dedicate round-the-clock effort to satisfy the basic needs of the people stranded by the rains,” said the president.
With more rain forecast, the governor called on residents, to head for higher ground and stay away from flood-prone areas identified by the civil defense agency.
He said 4,400 residents have been evacuated but thousands more are waiting to be rescued from their flooded homes.
According to a civil defense bulletin, 154 cities have been affected by natural disasters.
