Severe storms continue into the early hours: alerts remain in effect in many regions.

BarcelonaShowers and heavy storms have affected many regions this Wednesday, leaving some downpours. The heaviest so far have fallen in parts of the Pyrenees, Pre-Pyrenees, Central Catalonia, and the Barcelona coastal area, with over 40 l/m² of rainfall in some places in a short period of time. There have also been significant hailstorms, in some cases leaving stones up to 5 centimeters in diameter (you'll find the most important data and images at the end of this report).

Instability will continue throughout the night, overnight, and into the early morning, with showers and thunderstorms that could be intense and accompanied by hail, hail, wind, and downpours. They will primarily affect the northern half, the coast, and the pre-coastline. The nighttime coolness will be very noticeable, also on the coast, and Thursday will be not very warm, with an atypical atmosphere more typical of late summer. The weather will not clear up tomorrow with traces of showers in some areas, but the most pronounced instability will move between the Balearic Islands and the Valencian Community.

Night and early morning: showers and thunderstorms

This afternoon's showers and thunderstorms will continue into the evening, overnight, and early morning. They will primarily affect the regions of Barcelona, Girona, and the rest of the coast and pre-coast. Pay attention to Camp de Tarragona and southern Barcelona, as this is where the heaviest downpours could fall. Locally, there will be showers with hail or stones. Meteocat maintains alerts for the coming hours for heavy rain in several areas of the country. The weather is suddenly cooler.

Thursday: unusually cool and unstable

Until early morning, scattered, less significant showers will still fall in parts of the coast, the pre-coastline, and the northeastern interior. However, they will diminish, and the sun will predominate in the west throughout the day, with little rain expected for the rest of the morning. In the afternoon, cloudy skies will again gather in mountain areas, bringing some showers and thunderstorms to parts of the Pyrenees, the Pre-Pyrenees, inland Girona, the pre-coastline of Barcelona, and northern Central Catalonia. They will be more scattered and less significant, but some showers may still be locally intense.

The most severe instability will move to the Balearic Islands and the Valencian Community, especially to the south of the Valencia and Alicante regions. Showers will fall in these areas, while the most intense storms are expected between Ibiza and Cap de la Nau. Aemet has activated alerts for these areas. The mistral and tramontana winds will blow strongly this morning in the Ebro and Empordà, creating complicated maritime conditions.

All this with a marked drop in temperatures. It will be a cool or rather warm day for the dates, with values clearly below average.

No intense heat in sight

There will still be some showers remaining on Friday, but the weather will improve, and the weekend will be generally quite pleasant and enjoyable. Temperatures will gradually rise, but will remain moderately warm and very bearable. Nights will remain fairly cool and provide a good night's sleep, and no episodes of intense heat are in sight.

Balance of the strong storms

Showers and thunderstorms have affected many regions this Wednesday, unevenly. They have been especially intense in parts of the Pyrenees, Pre-Pyrenees, Central Catalonia, the northeast, and the Barcelona pre-coast. So far, rainfall has exceeded 40 l/m² where it has rained the most, but the irregularity of the storms means these figures are very localized. However, in coastal and western areas, there has been no rain so far. There have also been significant hailstorms, such as in Caldes de Montbui (Vallès Oriental) and in other regions such as Pallars Jussà. These are some of the most significant records and images of the showers and hailstorms.
