Heavy rainfall over the weekend, exceeding 150 mm in parts of central Buenos Aires province, has prompted ongoing monitoring of key agricultural areas and raised recent concerns. Forecasts predict a extremely unstable week, with intense heat, abrupt changes, and further storms, potentially bringing above-normal precipitation to the core Pampas region.
Weather Concerns Mount for Argentine Farmlands
With already saturated soils in regions like Azul, Olavarría, and other parts of central Buenos Aires, the risk of excessive moisture is again a primary concern during the harvest season. The collection of crops such as corn has been halted by the recent precipitation.
Experts agree that a highly dynamic weather pattern is developing. This will begin with several days of unusually high temperatures for this time of year, followed by a strong shift with the arrival of a cold front that will generate rains and storms of varying intensity.
Climatologist Germán Heinzenknecht explained that “the epicenter of the rains is in the center of Buenos Aires province,” emphasizing this region. Although noting that areas to the north and northeast may better absorb rainfall and are not currently facing such a complicated outlook, the situation is different in central Buenos Aires.
The areas of Olavarría and Azul are particularly delicate, as significant rainfall has already occurred and more is possible in the coming days. Heinzenknecht warned, “It’s the most complicated part, due to the fact that it has already rained a lot and more water will be added between Wednesday and Thursday, making it vulnerable again to excess water.” He did note that the current situation is not as severe as last year, but cautioned that “it still becomes much more complex.”
Conversely, not all regions are facing the same conditions. Heinzenknecht explained that rainfall is generally positive in the south of the core zone and in sectors of Córdoba, not generating excess, while to the north, rainfall is not reaching those areas. “To the north it is blocked, the rains do not arrive,” he stated.
Meteorologist Leonardo De Benedictis anticipates a “hyperdynamic” week, with marked changes in a short period. He detailed that the first half of the week will bring very high temperatures, even extreme for this time of year, followed by a significant drop towards the weekend.
This shift will create conditions for storms. “A drastic change is coming that will cause rains and storms of varying intensity. Again, the south of Buenos Aires, Córdoba, Santa Fe and La Pampa may experience strong to very strong storms,” he noted. A brief pause with more isolated phenomena is possible towards Thursday and Friday, but the bad weather is expected to return over the weekend, with “Saturday and Sunday again with rains and storms.”
Strong winds are also a concern, as the contrast between the heat and the incoming cold air could generate significant gusts. “With that thermal contrast we can have very significant gusts,” De Benedictis warned.
The weekly report from the Secretariat of Agriculture also alerted that the climate scenario will remain active in the coming days, with weekly rainfall expected to be above normal in the core Pampas region and below normal in the NEA and north of the Litoral. A demanding thermal pattern is also predicted, with an average temperature expected to be higher than normal in the north of the country, especially in the NOA.
