- Risks highlighted by SMN: Heavy rainfall, lightning, and strong winds.
- Most affected area: Northern Corrientes, with possible extension to other regions.
- Critical period: Night of June 4 through the early morning of June 5.
Yellow alert: What it means for Corrientes
The yellow alert issued by the SMN signals weather phenomena with the potential to cause disruptions, though not as severe as orange or red alerts. In Corrientes, the storms could lead to flooding in urban areas and challenges on rural roads. Reduced visibility and strong winds also pose concerns for drivers and outdoor workers.
The SMN advises residents to avoid flood-prone areas, such as inundated streets, and to keep a safe distance from poles and trees that could be damaged by winds. These precautions are critical to ensuring safety during the period of adverse weather.
Expected weather conditions
Temperatures in Corrientes, ranging from 13°C to 26°C, reflect the typical transitional climate of early June. High humidity, close to 100%, contributes to the formation of heavy clouds, increasing the likelihood of rain. SMN data suggests rainfall accumulations between 15 and 40 mm in some areas, with isolated spots potentially seeing higher volumes.
In the capital, the sky is expected to remain partly cloudy during the day, with a 70% chance of storms at night. Regions like Concepción, Mercedes, and Paso de los Libres, in the north, are among the most vulnerable due to the predicted intensity of the rainfall.
- Minimum temperature: 13°C, with a cooler feel at night.
- Maximum temperature: 26°C, with moderate warmth during the day.
- Humidity: High, near 100%, favoring intense rainfall.
- Winds: Predominantly southerly, with gusts up to 30 km/h.
Preparations by residents and authorities
Residents of Corrientes, particularly in rural and flood-prone urban areas, are taking preventive measures. In cities like Mercedes and San Roque, efforts include clearing ditches and drains to prevent flooding. Small business owners are securing their inventories, while farmers monitor crops that could be impacted by excessive rain.
Local authorities, in coordination with Civil Defense, have intensified weather monitoring. Emergency teams are on standby to respond to fallen trees, power outages, or road incidents. Communication with the public is being reinforced through radio broadcasts and social media alerts.
History of storms in the region
Corrientes has a history of severe weather events, particularly between May and June, when low-pressure systems often bring heavy rainfall. In December 2024, the province faced a red alert, with winds exceeding 120 km/h and rainfall accumulations surpassing 300 mm in a few days. Those events caused widespread power outages and disruptions across multiple cities.
While the current alert is yellow, memories of past events keep residents vigilant. The region’s topography, with rivers and floodplains, heightens the risk of inundation during periods of intense rain.
Recommended safety measures
The SMN and local authorities have shared guidelines to reduce risks during the storms. These recommendations are widely disseminated to ensure residents are prepared.
- Avoid flooded areas: Do not cross inundated streets or bridges, even in vehicles.
- Stay clear of poles: Avoid contact with exposed or fallen electrical cables.
- Secure loose objects: Store items on balconies that could be blown away by wind.
- Monitor alerts: Follow SMN updates through official channels.
- Prepare for emergencies: Keep flashlights and basic supplies ready in case of power outages.
Potential impacts on local activities
The forecasted storms could disrupt various activities in Corrientes, from commerce to transportation. In urban areas, the risk of flooding may lead to temporary road closures and traffic delays. In rural areas, heavy rainfall poses a threat to sensitive crops, such as rice and citrus, which are prevalent in the region.
Small businesses, including restaurants and shops, are bracing for reduced foot traffic due to the weather. The cancellation of outdoor events, such as fairs and cultural activities, is also anticipated.
Real-time monitoring
The SMN operates a continuous monitoring system, using radars and weather stations to track rainfall developments in Corrientes. Updates are issued every few hours, particularly for areas under alert. This work is supported by regional agencies, such as the Posadas Meteorology Directorate, which provides additional data for northeastern Argentina.
Advanced technology enables more accurate storm predictions, facilitating effective preventive measures. Residents can access these updates through apps or official websites, enhancing safety.
Forecast for the coming days
Following the storm system on the night of June 4, the forecast indicates a gradual improvement in weather conditions. For June 5, the SMN predicts cloudy skies but a lower likelihood of intense rainfall. Temperatures are expected to drop slightly, with lows near 10°C in some areas.
However, the risk of instability persists in the northern province until the end of the week, with possible isolated showers. The situation will be reassessed daily, with alerts updated as needed.
News summary
The National Meteorological Service issued a yellow alert for Corrientes, forecasting strong storms on the night and early morning of June 4, 2025, with the greatest impact in the northern region. The rains, starting in the afternoon, may cause flooding, power outages, and traffic disruptions, prompting precautions from residents. Temperatures will range between 13°C and 26°C, with high humidity. Authorities and communities are preparing to mitigate damages, while the SMN monitors conditions in real time. The forecast suggests improvement on June 5, though isolated rains may persist.
