The Puente de Mayo begins with rain in much of Spain as the Agencia Estatal de Meteorología (AEMET) has activated yellow alerts (risk) on Thursday, May 1, 2025, in the communities of Castilla y León, Andalucía, and in the autonomous city of Ceuta due to the forecast of heavy rains and storms during the last hours of the afternoon.
In Andalucía, the most abundant rains are expected in Grazalema and the Estrecho (Cádiz), and in Ronda and the comarcas of Sol and Guadalhorce (Málaga), where accumulations of up to 15 liters per square meter in one hour could occur. Ceuta will also register similar precipitation from 21:00 hours.
In these zones, a warning for storms has also been issued, and AEMET forecasts that these warnings will continue into Friday, May 2, 2025. The community of Castilla y León will experience storm alerts starting at 14:00 hours, particularly affecting the provinces of Burgos and Palencia.
Meanwhile, the Canary Island of La Palma is under a yellow warning for coastal phenomena, as a strong storm is expected to hit the coast, bringing waves of up to four meters high. The general prediction for Thursday indicates a widespread increase in temperatures across the country, especially notable in the southwest peninsula. In Palma and Zaragoza, temperatures will be around 28 degrees, while Granada and Murcia could reach 30 degrees.
The weather situation will complicate further from Friday, May 2, 2025, coinciding with the Día de la Comunidad de Madrid, as an Atlantic storm is expected to sweep across much of the country. This front will lead to widespread precipitation, with intense showers particularly in areas of northern Extremadura, southern Castilla y León, and the central system, especially in the Sierra de Guadarrama (Madrid).
While some regions in the eastern Cantabrian, northeastern Catalonia, and parts of the southeast may avoid rain, the rest of the territory will face a period of instability that will continue into Saturday. On that day, storms will extend to the western peninsula and areas of the eastern third, including Aragón and interior Mediterranean regions.
By Sunday, May 4, 2025, Galicia, the Cantabrian region, the Pyrenees, Castilla y León, the north of Extremadura, and the central peninsula will still be under the storm's influence, while the Mediterranean area and the archipelagos will enjoy more stable skies.
Temperatures are expected to gradually decrease over the weekend, although they will remain pleasant in many areas. In the Ebro valley, the southeast peninsula, Balearic Islands, and Andalucía, temperatures may exceed 25 °C, and in provinces like Almería or Granada, they could even reach 30 °C.
As the new storm moves southward, it will impact the Canary Islands, leading to a reduction in rainfall intensity across the peninsula, though some areas will still experience showers. On Thursday, irregular showers are expected in the high areas of the north and center, with intensification on Friday, May 2, 2025, throughout the country, particularly in Galicia, Extremadura, and Castilla y León.
In Extremadura, yellow alerts will be activated for rains and storms on Friday, May 2, 2025, particularly in the north of Cáceres, Villuercas-Montánchez, south of Badajoz, and the Siberia extremeña. The most affected area will be the north of Cáceres, where rainfall could accumulate to 40 liters per square meter in 12 hours and 15 liters in just one hour. Alerts will be activated at midnight on May 1, 2025, and will extend until 14:00 hours on Friday, with the exception of the north of Cáceres, which will be under warning for 24 hours.
In the rest of the areas, rainfall could reach up to 15 liters in one hour. The forecast for Friday indicates that minimum temperatures will see a moderate increase while maximum temperatures will decrease, generally ranging between 11 and 24 degrees. On Wednesday, April 30, 2025, all AEMET meteorological stations in the region recorded rainfall, with Aliseda being the rainiest locality at 28 liters per square meter.
As the weekend approaches, the situation is expected to calm down, but cool temperatures and occasional showers will persist in the north. The AEMET warns citizens to exercise caution on the roads, particularly regarding potential landslides and flooding.
In summary, the Puente de Mayo is set to be marked by a series of weather disturbances, with significant rainfall and storms expected across various regions. Citizens should remain vigilant and prepared for changing conditions as the holiday weekend unfolds.
