The death toll from massive floods in southern Brazil has reached 100. Rescue teams continue to search for dozens of missing people Al Jazeera reported.
Nearly 400 municipalities have been affected after days of heavy rains that flooded the Brazilian state of Rio Grande do Sul.
The floods have injured hundreds of people and forced 160,000 people from their homes since Wednesday, and the state's civil defence agency said 128 people were still missing.
Brazil's National Center for Natural Disasters said the southern part of the state was at "high risk" of further flooding during the day.
He reported that rainfall is expected to resume although not significant in volume, in many places, the water table is already high and the soil is saturated.
Many residents do not have access to potable water, electricity, or even the means to call for help, as telephone and internet services are down in many places.
State governor Eduardo Leyte warned earlier this week that the death toll was likely to rise as "the emergency continues to develop" in the state capital, Porto Alegre, and other areas.
Only two of Porto Alegre's six water treatment plants are functioning, the city hall said, and hospitals and shelters are supplied with water from tankers.
Brazilian President Luiz Inacio Lula da Silva promised that "there will be no lack of resources" to meet the needs of residents.
"We understand the difficult financial situation Rio Grande do Sul is in," he said at an event in Brazil, adding that he wanted to ensure the state got "everything it's due."
"We still don't know the exact extent of the floods, that will become clear to us only when the water level normalizes," Lula said.
About 15,000 soldiers, firefighters, police and volunteers worked across the state to rescue those trapped and transport aid.
On May 8, the Brazilian Navy was expected to send its largest ship in Latin America, the NAM Atlantico, to Rio Grande do Sul with two mobile water purification stations./BGNES
