Drought to spread from south to east-central areas in Brazil in March -climate impact

RIO DE JANEIRO, BRAZIL – The drought, which has hit the southern region of Brazil the hardest, will now spread to areas in east-central Brazil, according to the Climate Impact Company, a partner company of AgResource Brazil. The weather pattern will change significantly in March, according to the updated weather forecast.

Next month, weather in South America is expected to become “dramatically drier.” AgResource points out that the forecast has changed significantly, as last month it was expected that parts of the Southeast and Midwest would remain wet.

“But now the drought recorded in Paraguay, southern Brazil, and Argentina in recent months is expected to extend northward. Areas previously wet in Brazil will become dry in March, and the above-average rainfall pattern will shift to the northwest of the continent,” the consulting firm’s report said.

Meanwhile, they add that the abnormal heat that was limited to Argentina, Rio Grande do Sul, and Paraguay in the January forecast is expanding to the southeast and much of eastern Brazil. The drought pattern in east and central South America continues to strengthen and extend northward.”

By April 2022, wet weather is expected to shift to the north and northwest of the continent, while Brazil’s southern and eastern halves are unlikely to receive significant rainfall.

“Southern Brazil remains drier than normal as drought persists in this region. It is worth noting that this condition will be even more severe in eastern Argentina. The above-average heat prevails in Argentina and moves toward eastern Brazil in April,” AgResource Brasil said.

“Heading into winter, May will be warmer than usual in southern Brazil and most of Argentina, and potentially quite warm in northern Argentina and parts of Paraguay. Meanwhile, areas that have already suffered from drought will be drier than usual.

The wet pattern will remain concentrated mainly in the northern part of the continent. At this point, La Niña is no longer underway, and the question is whether a weak El Niño could become more common by the end of the year,” analysts said.

The biggest concern, according to them, is the second corn harvest. “The situation is likely to be most complicated in northern Argentina, central and southern Paraguay, and a small Mato Grosso do Sul area, where high heat is expected. Meanwhile, the country’s extreme north will be very humid, while the rest of the country will have average weather for this time of year.
