Le Service météorologique national a émis une alerte jaune pour la cyclogénèse et de fortes tempêtes pour ce jeudi.

The National Weather Service issued a yellow alert for cyclogenesis and strong storms for Thursday, August 8, warning of intense rainfall, strong gusts of wind, and hail over the Greater Buenos Aires area and several provinces in Argentina. The phenomenon is linked to a process of cyclogenesis in the east of the country, which will favor the formation of intense low-pressure systems and a subsequent significant drop in temperature. According to data from Meteored Argentina, instability will begin to consolidate around midday after a morning marked by fog and humidity. As the day progresses, the entry of a mass of polar air will cause the wind to rotate toward the southern sector, with gusts reaching up to 70 km/h and precipitation accumulating rapidly in short periods. The weather alert extends beyond the Buenos Aires region. Reports from Cadena 3 indicate that the storm system will strongly impact areas south of Formosa, Chaco, Corrientes, Misiones, and northern parts of Santa Fe and Entre Ríos. In these regions of the Litoral, storms could be accompanied by heavy electrical activity and hailfall, with gusts potentially exceeding 90 km/h. In the mountainous regions, the arrival of the system will bring additional complications. Meteored noted that the cold air mass will intensify snowfall in Neuquén and other mountainous areas of Mendoza and San Juan. These snow showers will keep mountain communities on high alert during the latter part of the event. Meanwhile, the center of San Juan and western La Rioja remain under watch due to the presence of the Zonda wind. This dry and warm wind will generate gusts above 70 km/h, causing temporary increases in temperature and severe reductions in visibility before the arrival of the polar air. On Friday, August 9, temperatures in the Greater Buenos Aires area are projected to reach minimums of 5°C in urban zones and lower values in suburban areas. Forecasts from the official body suggest that the cold will intensify throughout the weekend, with Sunday marking the lowest readings of the period, around 4°C. In response to the risk posed by the intensity of the wind and rain, the National Weather Service advised the population to avoid outdoor activities during the critical moments of the storm. Authorities also recommended removing or securing objects that might be blown away by the wind and exercising caution while traveling on roads and avenues. The alert has drawn attention to broader climate patterns, including records set in Antarctica. July saw the lowest temperature recorded on the planet in 14 years, highlighting ongoing shifts in global weather systems. While some reports focus on the immediate impacts of the storm, others point to longer-term implications, such as the influence of Antarctic conditions on regional weather patterns. These observations underscore the complex interplay between local meteorological phenomena and larger climatic trends. As the storm system continues its progression, further updates are expected from the National Weather Service and other monitoring agencies. Residents are urged to stay informed and take necessary precautions to ensure safety during this period of inclement weather.
