A powerful storm system named Sunday is approaching. Starting next Saturday, adverse weather is expected across nearly the entire country, bringing very strong winds that could top 70 to 80 km/h, with gusts surpassing 100 km/h in the northwest of the peninsula, along the Mediterranean coast, and the Balearic Islands, especially in coastal and mountainous zones.
According to the Spanish Meteorological Agency (Aemet), Sunday marks the fourth named storm of the season from the southwestern group affecting Spain, with the system circulating around the Iberian Peninsula and nearby islands and then crossing toward the British Isles. This weather disturbance is set to introduce continuing unsettled conditions across much of the country, including Galicia and Cantabria, where sea storms and high waves will be common; Atlantic seas could reach 7 to 8 meters, while the Mediterranean could see waves around 4 to 5 meters.
Del Campo explained that the rain will begin on Saturday across much of the peninsula outside the Mediterranean region, with the heaviest and most persistent rainfall concentrated in Galicia and surrounding areas, as well as the Central Pyrenees and the Western Central System, particularly to the north and south of Cáceres and within Salamanca and Ávila.
Temperatures are expected to rise across the country as winds shift to a milder flow influenced by the Sunday wind regime. Snow levels are anticipated to be between 1,500 and 1,700 meters.
From Sunday onward, the storm is likely to ease, but rain will continue to fall in Galicia, western Castilla y León, and the mountainous regions. Even with persistent rain in some plateau areas, the winds may ease compared with the previous day.
The outlook suggests a return to more stable, anticyclonic conditions next week, with rainfall mainly confined to Galicia and Cantabria. In other regions, clearer skies, very low temperatures, and calmer winds could bring the first night frosts of the season to elevated areas.
