A "powerful anticyclone" is coming that will bring a weekend of rain, gusts exceeding 55 km / h and very cold weather: the affected areas

A powerful anticyclone is set to bring a weekend of rain, gusts exceeding 55 km/h, and very cold conditions to several regions of Argentina. The weather system will create contrasting temperatures and varying atmospheric conditions, marking another shift in August’s weather patterns. This new front will affect areas across the country, particularly in the south and northeast, with heavy rainfall anticipated along the coasts of Santa Cruz and parts of Patagonia. The anticyclone, originating from the Southern Pacific and extending into central and northern Patagonia, is expected to trigger intense precipitation over the region. According to reports from the National Weather Service (SMN) and specialized platforms such as Meteored, the system will bring substantial rainfall and wind gusts surpassing 55 km/h along the coastlines of Santa Cruz. These conditions will likely lead to a noticeable drop in temperatures throughout much of the national territory. During Saturday, the anticyclone will maintain stable conditions in southern Patagonia, though some light showers are expected in coastal areas of Santa Cruz and Tierra del Fuego, accompanied by winds reaching up to 55 km/h. Meteored notes that the anticyclone will remain largely blocked by a low-pressure system further north, resulting in minimal changes in weather conditions. However, in locations such as San Julián, Puerto Deseado, and parts of Chubut's coastline, more pronounced rainfall is forecasted. As the weekend progresses, the arrival of the anticyclone will dominate almost all of Patagonia, driven by a new high-pressure center in northeastern Santa Cruz. This phenomenon will bring significantly lower temperatures, beginning its movement toward Buenos Aires later in the day. The transition will mark a sharp contrast in weather, with cooler air masses replacing the previous warmer conditions. In Buenos Aires, the weekend is expected to feature clear skies but with a noticeably colder atmosphere. On Saturday, the minimum temperature is projected to reach 3°C, while the maximum would be around 14°C. Sunday will see temperatures fluctuate between 4°C and 13°C, with partly cloudy skies. Precipitation is not anticipated during this period, despite the broader regional changes. The impact of this weather pattern will vary across different zones, with the southern regions facing more severe conditions than the capital. Local authorities have been advised to monitor developments closely, especially in coastal and mountainous areas where sudden temperature drops and strong winds could pose challenges. Travelers and residents should prepare for potential disruptions, including reduced visibility due to rain and the need for warm clothing given the expected chill. As the anticyclone continues its influence, further updates from the National Weather Service and other monitoring agencies will provide additional insights into how these conditions might evolve through the coming days.
