The State Meteorological Agency (Aemet) has predicted that starting this Friday the formation of a DANA will lead to a "change in weather" that will bring intense showers and storms in areas of the interior of the peninsula and a progressive and "notable" drop in temperatures. He pointed this out in an informative note released this Thursday through his social networks. In that message, the agency anticipates this meteorological change "after a prolonged period of time characterized by widespread high temperatures and the presence of storms mainly in areas of the eastern third of the peninsula."
"Starting this Friday, the formation of a DANA, from an Atlantic trough, which will be located during the weekend in the area around the Peninsula, will lead to a change in weather consisting of the formation of showers and intense storms in large areas of the interior of the peninsula," he explains. On the other hand, he adds that "the low-level subtropical air mass, warm, dry and with suspended dust, will be replaced by another one, of Atlantic origin, cooler and cleaner, giving rise to a progressive decrease in temperatures until reaching values more typical of these dates."
In this way, on Friday afternoon "the Atlantic trough will approach the west of the peninsula, evolving into DANA at the end of the day" and in the afternoon storms will occur in large areas of the interior, except for the southwestern quadrant, which will lead to showers and strong gusts of wind, accompanied by hail. The most intense are expected around the Iberian system and in areas of the eastern interior of the peninsula, where the intensity of the showers and gusts of wind could be very strong. In addition, Aemet points out that although temperatures will begin to drop in the northwest and central half of the peninsula, there are still fairly widespread heat warnings.
Given this situation, the Aemet has activated weather alerts in all the autonomous communities - with the exception of the Canary Islands - for this Friday. The heat will put Andalusia, Aragon, Castilla-La Mancha, Catalonia and Madrid on orange warning; while the Balearic Islands, Castilla y León, Extremadura, Galicia, Murcia, Navarra, La Rioja and the Valencian Community will be under a yellow warning due to high temperatures. Due to rain and storms, Andalusia, Aragon, Asturias, Cantabria, Castilla y León, Castilla-La Mancha, Catalonia, Murcia, Navarra, the Basque Country, La Rioja and the Valencian Community will be on alert. The areas most affected by the abundant rainfall will be: Teruel, Cuenca and Valencia, where the orange alert will be activated. In Galicia, the fog alert will also be in force.
Saturday, "peak" day
During this weekend, the agency predicts that "with DANA located in the interior of the peninsula, showers and storms will be quite widespread, although less likely in areas of the southwest of the Peninsula and Galicia, and will also affect the Balearic Islands." Again, the intensity of the showers and gusts of wind will be strong in general and very strong locally, although Aemet admits that it is difficult to specify specific areas at this time.
He also considers "the formation of hail, even large (greater than 2 cm), likely" and anticipates that temperatures will drop "significantly, especially on Saturday, reaching values close to normal." The note clarifies that "the peak day of this episode, in principle, will be Saturday, both due to the extent and intensity of the storms and the magnitude of the thermal drop."
The Aemet has activated alerts in 14 autonomous communities for that day. For rain and storms, Andalusia, Aragon, the Balearic Islands, Cantabria, Castilla y León, Castilla-La Mancha, Catalonia, Madrid, Murcia, Navarra, the Basque Country, La Rioja and the Valencian Community will be on warning. Due to high temperatures, the Balearic Islands, Catalonia and Galicia will be on notice. In this last community the fog alert will also be in force.
