Persistent rain in the South is expected to halt work on crops, says meteorologist from Canal Rural

Excessive rain in southern Brazil is expected to continue to impose difficulties on field activities in the coming weeks.

According to Canal Rural meteorologist Arthur Müller, the action of an atmospheric river maintains the forecast of storms, with accumulations exceeding 100 millimeters in several areas, a scenario that tends to delay agricultural operations and increase the risk of flooding.

The most critical situation continues in Rio Grande do Sul, where the soil is already saturated after consecutive days of intense rain.

“In the next 48 hours, we will have rainfall exceeding 100 millimeters in the center-north of Rio Grande do Sul, in Santa Catarina and in the south of Paraná, which should harm field work and also leave these areas under alert for flooding and landslides, especially in Rio Grande do Sul, west of Santa Catarina and south of Paraná”, said Müller, during Mercado & Companhia this Monday (20).

A month's worth of rain in just two days

The volumes recorded in recent days help explain the concern. In Quaraí (RS), there were 141 millimeters of rain in the last 48 hours, while Rosário do Sul accumulated more than 100 millimeters in the same period.

According to the meteorologist, this volume is practically equivalent to the average expected for the entire month of July.

"It's a time of year when the expected amount for the entire month is between 100 and 120 millimeters. In just two days it has already rained the equivalent of what was expected for the entire month, and there is still rain in the next 48 hours."

In addition to the accumulated highs, the state remains at risk of storms with hail, wind gusts exceeding 100 km/h and the possibility of atmospheric microexplosions.

Saturated soil increases concern

In the field, the main concern is the difficulty in accessing production areas. With the soil soaked, operations such as winter crop management, spraying, fertilization and other mechanized activities may be interrupted or delayed.

Excess humidity also favors erosion problems, makes water drainage difficult and increases the risk of flooding in productive areas.

According to Müller, the scenario is still far from normalization. “The soil is saturated in Rio Grande do Sul and we will still have heavy rain in the coming days”, he warned.

Instability is expected to persist until the end of the month

Although the rain also advances over Santa Catarina, western Paraná and southern Mato Grosso do Sul, Rio Grande do Sul should continue to concentrate the largest accumulations.

The forecast indicates a brief reduction in precipitation before the arrival of a new front of instability in the last week of July.

“We will have a short break of about four days and then another 100 to 150 millimeters of rain will return to Rio Grande do Sul. Until the end of July, we will have problems with rain in the state of Rio Grande do Sul”, he said.

According to the meteorologist, a more consistent change in the weather pattern, with the return of a more intense cold air mass and a reduction in rainfall, should only occur at the beginning of August. Until then, rural producers in the South region will continue to face difficulties in carrying out activities in the field due to the sequence of storms and the persistence of waterlogged soil.
