After a stable Tuesday, the weather in the Buenos Aires Metropolitan Area changes abruptly. Starting this Wednesday, May 6, a cyclogenesis will begin to develop over the central-east of the country, generating intense rains, storms, and strong winds.
In this context, the phenomenon will mark the end of the autumn truce. Additionally, its effects are expected to extend until the weekend, with an unstable meteorological scenario.
On the other hand, thermal variations had already been anticipating this change. After recent frosts, the entry of humid and warm air will modify conditions in much of the region.
Forecast and affected areas
According to the National Meteorological Service, Wednesday will begin with a yellow alert for storms. However, by Thursday morning, the situation will escalate to an orange alert.
Consequently, strong to severe storms are expected, with possible hail and gusts that could reach 70 km/h. Likewise, accumulated precipitation could be significant.
In the rest of the country, the outlook will also be complex. The Litoral, the north of Patagonia, and regions of Cuyo will experience rains, snowfalls, and strong winds, with variable impacts depending on the area.
What is cyclogenesis and why does it generate intense storms?
The cyclogenesis is an atmospheric process through which a low-pressure system forms. This phenomenon occurs when a mass of warm and humid air meets another cold and dry one.
As a result, the warm air rises, cools, and condenses, forming clouds of great development. This process leads to storms, intense rains, and strong winds.
Additionally, the system begins to rotate, intensifying the instability. Therefore, although it is a frequent phenomenon, its impact can be significant depending on its intensity.
What precautions should be taken during an orange alert?
In the face of an orange alert, it is essential to take preventive measures. First, it is recommended to avoid outdoor activities during the development of intense storms.
It is also important to secure objects that may be displaced by the wind. Loose items on balconies or patios can become hazards during strong gusts.
It is also advised to avoid circulating in flood-prone areas. Intense rains can cause rapid flooding, especially in urban areas with limited drainage.
Climatic impact and thermal drop
After the event, a gradual improvement in conditions is expected. However, relief will come accompanied by a marked temperature drop.
In this sense, the entry of cold air will reinstall a winter environment. Minimum temperatures could be below the usual for this time of year.
Thus, cyclogenesis will not only bring storms, but also a significant change in the climatic pattern. This type of event reinforces the need for adaptation in the face of increasingly variable meteorological scenarios.
