The red alert remains activated in light of the new episode of torrential rain expected over the coming hours in many coastal, pre-coastal, and northeastern regions of the country. The tropical characteristics of this exceptional situation create the possibility that a small medicane (Mediterranean hurricane) could be generated. Various meteorological models, such as the Arome, indicate the formation of a convective vortex that could approach the central Catalan coast, with strong wind gusts and intense precipitation, with accumulations exceeding 200 mm. This convective phenomenon generates great uncertainty. We repeat that it is an unlikely scenario, but, in the event that it occurs, it is quite dangerous.

Streets flooded with water and full of mud and branches, some rivers and streams at their limit, and parking garages and in some cases schools with their ground floors flooded. Chaotic mobility, with Barcelona's Ronda de Dalt closed for five hours, a good part of the metro lines affected, trains running off-schedule, and some flights that could neither take off nor land at El Prat airport. This has been the scene experienced this Tuesday in a large part of the metropolitan area, the Anoia, and the Penedès, on a new day of torrential downpours that have once again strained the country. During the morning and midday, the downpours were in the metropolitan area, but this evening they moved to Girona, to the point that Civil Protection sent a new ES-Alert to the Baix Empordà for torrential rains until 9 p.m. in the northeast of the region.

During this weekend and the coming days the weather will be identical, with some exceptions. Temperatures have normalized and only towards Monday will they be able to rise a little in the West. Apart from sun, some morning fog and some thin clouds, the arrival of weak north and northwest winds will stand out, but little else.

A man has died after being swept away by a stream in Garraf amidst the heavy rainstorm in Catalonia. The Generalitat Fire Department located his lifeless body at midnight, about 500 meters from where they found his car, in an accessible area, and recovered the body. According to a witness, a vehicle had become stuck in the stream and a person tried to get out, ending up being swept away by the current.

The unbridled heat continues to set temperature records across the country. This Saturday, the highest maximum for a September since 1914 was recorded again at the Fabra Observatory, with 35.3 °C. With this historic value, there are already four records broken in the city of Barcelona since the beginning of the month. In Ponent, in the interior of the Ebro, and in regions like the Priorat, temperatures reached or brushed against 41 °C, with a new September record at 64 of the 128 XEMA stations with more than twenty years of data.

The unbridled heat continues to set temperature records. Yesterday, Friday, 34.1 °C was recorded at the Fabra Observatory, the highest maximum since 1914 in a September in the city of Barcelona. In Ponent and the interior of the Ebro, temperatures soared again, reaching a sweltering 42.5 °C in Vinebre (Ribera d'Ebre) and up to 39.3 °C in the city of Lleida, the highest maximum in September since 1939. Therefore, it was the hottest September day recorded in Catalonia, with historic values for these dates in 77 of the 128 XEMA stations with more than 20 years of data.

The temperature climbed sharply again, with new records, this Thursday. At the Fabra observatory, it reached 33.1 °C, half a degree less than Wednesday, when 33.6 °C was recorded. Yesterday's value is the second highest since 1914 in a September in the city of Barcelona. In Ponent and the interior of the Ebro, they brushed against 40 °C (39 °C in Vinebre, one of the highest since 2022). If we take the set of Meteocat's automatic stations, 27 out of 128 broke the record for a month of September in 20 years of data, especially those located in Empordà, the Pyrenees, and Ponent.

Saturday morning thunderstorms discharged strongly offshore and those that hit land left intense downpours. In Baix Penedès, it discharged with great intensity and the showers were torrential. In El Vendrell, for example, they accumulated 146 l/m², 137 l/m² in Torredembarra and 109 l/m² in Calafell.

We are starting a stormy Saturday, but not throughout the territory. Thunderstorms are discharging strongly offshore and are reaching land. In fact, heavy showers and intense thunderstorms are expected between the central coast and the Costa Daurada. These showers will be intense and can accumulate 30 mm in just under half an hour, with significant accumulations, which have already reached up to 100 mm in a few hours. In Baix Penedès, it has discharged with great intensity and the showers have been torrential. In El Vendrell, for example, they have accumulated 129 mm and 113 mm in Torredembarra.

Eleven people have been injured to varying degrees due to the torrential rains that fell last night and this morning, flooding streets, campsites, car parks, and underpasses in the north of Tarragonès and Baix Penedès. The episode, which also caused road and rail line closures, was declared over at 4 p.m. and exceeded the Generalitat's forecasts. The Generalitat did not send any alert to the population via ES-Alert, presumably because the intensity of the downpours predicted for those hours was lower. The most serious incident occurred in Roda de Berà (Tarragonès): around two in the morning, the wall of a house on the town's promenade collapsed, and three people, who are from the same family, were trapped.

The approach of a cold air trough at high altitude has generated significant atmospheric instability and has already contributed to a drop in temperature. The strong contrast between the cold air at high altitude and the warm Mediterranean mass generated powerful clouds and the storms discharged with force, with some downpours and violent phenomena, such as strong gusts of wind, hail and sleet. The most affected regions were the central coast, the pre-coast and the northeast, with violent phenomena in Anoia, Alt Penedès, Baix Llobregat and the two Vallesos. You can follow the episode at this link:

The heat has ended with the arrival of a cold air mass. Temperatures of 40°C will no longer be repeated and the thermometer will drop, but this will be from tomorrow, with a noticeable cooling in high altitudes and inland, especially on Friday and over the weekend. On the coast, this Thursday, we will still suffer from sultriness due to increased humidity and a cloudier sky.

The heat will still be intense, especially in the interior of the country, where it will exceed 39°C again and could reach up to 40°C in the Lleida plain and the interior of the Ebro valley (and we will already have more than twenty days with such extreme values). The meteorological situation offers no respite regarding temperature due to the warm air mass from North Africa.

The heat will continue to be intense, especially in the interior of the country, where temperatures will again exceed 38°C in the Lleida plain or in the interior of the Ebro valley. The meteorological situation offers no respite in terms of temperature due to the warm air mass coming from North Africa. This dry tropical mass will again generate temperatures above average and will cause heat peaks of up to 40°C in Ponent and Ebre between Tuesday and Thursday. In fact, we have already had 19 days in Catalonia with temperatures equal to or higher than 40°C.

The passage of an upper trough has changed the weather in recent hours. Thunderstorms have discharged with intensity due to the generation of large convection clouds fueled by cold air that has dropped from more northerly latitudes. This clash of air masses with very different conditions has contributed to intense showers, accompanied by electrical apparatus, hail, and sleet (for example, yesterday afternoon, in Arbúcies). Until mid-afternoon on Saturday, we had already accumulated up to 35 l/m² in Sant Llorenç Savall and between 15 and 30 l/m² around the Montseny massif.

We wake up after a night that has been restless and very warm in general. Widespread tropical minimums have been recorded, but also many torrid ones on the coast, in the south, and in Ponent, with marked – and in some cases unbearable – sultriness on the coast and pre-coast. However, from today onwards, thermometers will start to drop, and the heat will become less extreme, with variable or partly cloudy skies and the risk of showers accompanied by mud in some regions. Despite everything, the very warm atmosphere, intense sultriness on the coast and pre-coast, and values above the climatic average will continue. No significant drop in mercury or a clearer unstable situation is expected for at least another seven to ten days.

Extreme heat has given a little respite this weekend, with very high values, but without the records of a few days ago. Yesterday, Saturday, many observatories in Ponent again brushed 38°C, with a lot of sultriness on the coast, due to low clouds. From today, temperatures will rise again and a new heat episode will begin. We are on the verge of what will be the third heatwave of the summer, when we will not yet have recovered from the second. The suffocating atmosphere gives no respite and after the sultriness we will again suffer a new influx of dry African air, with predicted values of up to 28°C at 1,500 m. This situation will cause thermometers to exceed 40°C again in many areas.

The mass of warm air that is affecting us these days is losing strength and will move away towards the center of Europe. However, the heat is still intense and, once again, we have registered values close to 38°C in some regions of Ponent and Empordà. For example, in Cabanes they reached 38.7°C yesterday and in Lleida, up to 38.6°C. During the rest of the weekend we will continue under the effects of the anticyclonic ridge and the incursion of very warm air and dust in suspension from North Africa. Next week the thermometers will drop, but the latest maps reduce the possibility of a forceful cooling.

A new pocket of warm air from North Africa will keep the atmosphere fully summer-like throughout this new week, after highs of 36 or 37 ºC were already reached this weekend in Ponent and the southern interior. This hot air will lower atmospheric pressure and generate a small thermal low that will favor the formation of afternoon thunderstorms, especially in the Pyrenees. In fact, some already reappeared yesterday, accumulating up to 25 l/m² in La Bonaigua (2,200 m, Pallars Sobirà), 15 l/m² in Puigcerdà (Cerdanya), and 3 l/m² in Núria (Ripollès).

A pocket of warm air from North Africa is making the atmosphere feel like mid-summer. This hot air will favor the formation of a thermal low over the Iberian Peninsula, which will cause the thermometer to rise and also form afternoon thunderstorms in the Pyrenees. This weekend, thermometers are generating highs higher than what would be expected for this time of year, with values that have exceeded 36°C in Empordà and Central Catalonia. For example, yesterday in Cabanes (Alt Empordà) and Artés (Bages) they reached up to 36.4°C. In Lleida or El Poal, they reached 35.6°C.
