Storms return to Rio Grande do Sul on the eve of the first round of elections; see the weather forecast

The state of Paraná is expected to face rain and storms during the election weekend, according to information provided by Climatempo, the National Institute of Meteorology (Inmet), and the State Environmental Technology and Monitoring System (Simepar).

Meteorologists agree that the arrival of a cold front late Saturday (the 3rd) will cause showers throughout the day, culminating in thunderstorms with strong winds, lightning, and hail during Saturday night and Sunday morning (the 4th).

On Friday, October 2nd, Climatempo predicts stable weather in Paraná, although there will be more cloudiness near the coast. There is a chance of light and isolated rain only in the north and northeast of the state, while the rest remains dry.

Simepar reports that, in most of the interior, the sun will appear in the morning, raising temperatures. In the western region, highs may reach 30ºC in the afternoon, when quick and isolated rains might occur between Campos Gerais and the north, but without signs of thunderstorms.

Saturday, October 3rd

On this Saturday, instability will begin to manifest in Paraná. Climatempo attributes this increase in cloudiness and showers to the action of low-pressure areas, initially more concentrated in the west, center, and north of the state, which may affect other regions.

Simepar indicates that despite persistent cloudiness in the east during the morning, the sun will emerge throughout the day. In the interior, the sky will have few clouds in the morning, contributing to warming. However, from the afternoon, localized and quick rains are expected, with the possibility of more intense showers.

During the night, the approach of a cold front will bring strong storms—characterized by intense rain, strong wind, many lightning strikes, and even hail—affecting the northwest, west, southwest, and south-central regions, according to Simepar.

Sunday, October 4th

On Sunday, the instability will intensify, and precipitation will spread across almost all of Paraná. Climatempo's forecast indicates that the combination of low-pressure systems with the advance of the cold front will favor periods of rain and showers, with potential for heavy rain, thunder, strong winds, and hail, especially in the west, north, and center of the state.

Simepar's models indicate that thunderstorms tend to concentrate between the early morning and the start of the morning. Although some rain events may occur in the afternoon and evening, they will be more sporadic. For Monday and Tuesday, the weather will remain very unstable due to the intensification of a low-pressure system in neighboring countries.

The weekend of the first round of elections in Brazil will be marked by rain and instability in various regions, requiring special attention for Sunday, election day. The South-Central region, in particular, is expected to face storms and intense winds.

São Paulo may record storms and wind gusts of up to 53 km/h, while Curitiba has a forecast of gusts up to 55 km/h, and Porto Alegre is expected to receive rain, thunder, and winds close to 50 km/h.

Climate changes are beginning to be noticed as early as Saturday, when a low-pressure area facilitates the return of storms to the South. On Sunday, these instabilities intensify or advance in parts of the South-Central region, while the North and Northeast maintain heat with isolated showers.

Conditions in the Southeast

In the Southeast, precipitation persists on Saturday and takes on new characteristics on Sunday. Although São Paulo has showers on Saturday, the arrival of a new cold front increases the risk of strong winds and storms on voting day, with gusts potentially reaching 53 km/h in the capital.

Rio de Janeiro and Belo Horizonte will also show weather changes. In Rio, the rain weakens on Sunday, with the maximum temperature forecast at 30°C. In Belo Horizonte, there is still a possibility of rain, concentrated mainly in the afternoon. Vitória may experience rain and thunderstorms during the morning.

Situation in the South

In the Southern region, Friday starts with cool and more stable weather. The transformation occurs on Saturday, when a low-pressure area located between northern Argentina and western Paraguay brings rain and thunderstorms to Rio Grande do Sul, which is under an orange alert for storms.

This instability continues until Sunday. Porto Alegre will have rain and thunderstorms, with gusts close to 50 km/h. Curitiba transitions from a cloudy Saturday without significant rain to a Sunday with heavy rain in the afternoon and winds of up to 55 km/h. Florianópolis may also record showers and thunderstorms.

Midwest and North and Northeast Regions

The Midwest remains unstable throughout the weekend. Brasília will have showers and thunderstorms on both Saturday and Sunday, with the maximum near 26°C. In Goiânia, Saturday will bring passing rain and thunderstorms, while Sunday may culminate in a storm. Campo Grande also forecasts showers on Saturday, but the rain tends to intensify on Sunday, with potential for storms and higher precipitation volume.

Among the highlights of the forecast, the North maintains the predominance of heat, despite several areas having showers. Palmas will have rain and thunderstorms on Saturday and new showers on Sunday, with a maximum of 27°C.

Forecast in the Northeast

In the Northeast, the scenario is varied, alternating between heat, dry weather inland, and sporadic rains on the coast. Recife is expected to have showers on Saturday and rain accompanied by thunderstorms on Sunday. Aracaju may also record rain on both days, with a maximum near 28°C. Teresina remains one of the hottest locations, potentially reaching 38°C.

In summary, the weekend combines high temperatures in the North and Northeast with a more pronounced climatic change in the South-Central region, especially on Sunday, when some voting areas may be affected by rain, storms, and strong winds.
