Where will it rain the most on Thursday?
Thus, from early Thursday, showers and locally strong storms are expected in a wide strip from the south to the north of the Peninsula, from the Strait to the eastern Cantabrian Sea. AEMET spokesman José Luis Camacho indicates that the main nucleus of precipitation will align from south to north. from the mountain ranges of Cadiz through the centre of the Guadalquivir Valley, Castilla La-Mancha, the Community of Madrid, eastern Castilla León, Aragon and reaching Rioja, Navarra and the Basque Country. Another cluster of significant rainfall is expected to occur in inland Galicia, southern Asturias and northern León.
Specifically, rainfall could be locally heavy and occasionally accompanied by hail in western Andalusia, areas of the southern plateau, Aragon, large areas of the interior of the northern half and eastern Cantabria. In turn, it may be locally persistent in areas of the centre and inland northeast. In other areas, rainfall will affect in a weaker and more dispersed way, except for northern Galicia, where cloudy skies and rainfall are expected, and the eastern Mediterranean area, where high clouds are expected.

The DANA will be in full force during the weekend in these areas
He Friday A DANA will approach the northwest of the peninsula, so showers and storms will continue. Although they will most likely remain restricted to the northwest quadrant of the peninsula, it is not ruled out that they will extend to the eastern third. The intensity would be lower than the previous day, but they could still be locally strong, most likely in the area around the Cantabrian mountain range.
For the weekendthe AEMET points out that the most likely scenario is that DANA will continue to move eastwards, crossing the Cantabrian Sea until reaching the Mediterranean late on Sunday. Showers and storms will therefore continue, most likely in the northern half of the peninsula, although other areas could also be affected.
Camacho indicates that on Saturday and Sunday The rains could especially affect the interior of Galicia and mountainous areas in the north of Castilla-León and Asturias, as well as the centre of the country, Aragon and the west of Catalonia and the Valencian Community.with the added presence of haze in much of the peninsula, which could leave rain with mud.

New DANA for next week
A delivery is expected to arrive on Monday next week. new DANA which would also be located in the northwest of the peninsula, so there will be showers and storms again, more likely in the north.
