Rainfall returned to Brazil's flood-hit Rio Grande do Sul state over the weekend and is likely to remain until Wednesday, according to meteorological firm Climatempo.
Downpours started in late April brought havoc to the state, flooding rivers and lakes and hampering several logistics points. Several state and national highways are still damaged and the state's main airport is likely to remain closed until the end of the year.
The weather had eased in the last few weeks, with lake and river levels dropping below flood levels since at least 9 June. But two new cold fronts brought rains to the state once again on 15 June, Climatempo said.
Rains are likely to reach an accumulated 200-300mm (7.9-11.8in) from 15-19 June in the state's central-northern and northwestern regions, Climatempo said. Other areas will receive 80-150mm in the same span.
Showers in the central-northern region of the state hit 50-60mm on 16 June alone, according to the US National Oceanic and Atmospheric Administration.
The Cai and Jacui rivers have reached above-flood levels once again, according to the state's civil defense. The Taquari River's levels are "above caution quotas," reaching 17m (55.7ft). Levels need to be below 5m to be considered normal.
Civil defense authorities have also issued a flood warning for those that live close to the Sinos River, asking them to evacuate risky areas.
Rio Grande do Sul is one of Brazil's main agricultural states. The US Department of Agriculture has cut the state's 2023-24 soybean production estimate because of the floods.
The extreme weather has left at least 176 dead and over 422,000 people displaced, according to the civil defense's latest report published on 14 June.
