At the beginning of the week, most of Spain faced significant atmospheric instability. The country’s national meteorological agency issued various levels of weather alerts for several regions, forecasting heavy rainfall and thunderstorms. The main risks are concentrated in the northeast and along the Mediterranean coast.
The situation is particularly severe in the province of Tarragona, which is under the highest danger level. Up to 90 liters of water per square meter may fall within an hour, posing a threat of sudden flooding. The rest of the province also faces a high probability of heavy rain—up to 150 liters in 12 hours, and in some areas, within even shorter periods.
Neighboring provinces such as Barcelona, Girona, and Lleida remain under orange and yellow weather alerts. Downpours and thunderstorms are also expected there, which may cause local flooding.
Other regions have also been highlighted on the weather alert maps. In the autonomous community of Aragon, particularly in Huesca and Teruel, rainfall of up to 60 liters per square meter is expected within a few hours, with possible hail and strong gusts of wind. The most vulnerable areas are the Pyrenees and Lower Aragon, where the most intense thunderstorms are anticipated.
In the Valencian Community, according to meteorologists, up to 120 liters of rainfall may fall in the province of Castellón within 12 hours, especially in the northern coastal area. Valencia and Alicante also remain under adverse weather forecasts: orange alerts have been issued for thunderstorms and the likelihood of hail, while a yellow warning is additionally in effect in Castellón.
The Balearic Islands have also been affected by the cyclone: a yellow warning is in place here, although precipitation intensity is lower than on the mainland. In Albacete and Murcia, brief showers and thunderstorms are possible, which may be accompanied by lightning.
In the rest of the country, the passage of the weather front will bring cloudy skies, with the highest chance of rain in the north and along the Mediterranean coast in the afternoon. Even in areas where the morning starts calmly, showers may occur by evening.
These weather changes will also impact temperatures. In most regions, maximum temperatures will drop, especially in Cantabria and the upper Ebro. In the center and west of the peninsula, however, a slight increase is expected. Minimum temperatures will rise in the east and remain unchanged in the Canary Islands. Despite the general cooling, nighttime temperatures in Mediterranean areas and the Guadalquivir valley will not fall below 20 degrees.
