Spain prepares for a “festival” of Atlantic storms

by

After a month of January that has been through water and snow (especially the last few weeks) and in which the Sun has made little appearance, all eyes are on how the month of February will start this Sunday. But a priori, the trend of constant rains seems to continue to prevail throughout the peninsular territory, as AEMET itself has pointed out in its latest bulletin. Boiled. This is undoubtedly the best summary we have for what we will see throughout the month of February, at least until the 22nd, which is what it covers the latest prediction from the national meteorological agency. And the fault is not an isolated front that reaches the peninsula, but a real carousel of fronts that will come and go of the national territory. This means that rainfall throughout the month of February will be above average, and a significant rainfall surplus is expected, especially in the west of the peninsula, Extremadura and the central-southern area. Something similar to what we have had in recent days, so we will not find any changes. They are persistent. As we say, prediction models such as ECMWF point to an atmospheric configuration that opens the door to the continuous arrival of storms from the Atlantic, a scenario that counteracts the initial forecasts that it was going to be a much drier winter than usual. And this change in the forecast completely breaks the trend of the dry environment and it is good news, since the reservoirs begin to fill for spring and summer. Something that is undoubtedly very positive in case half of the year the trend continues to be quite dry and that could be a serious problem if we had not now filled our water reserves. The cold on pause. If the water is the protagonist, the temperature is the supporting actress that surprises, and despite the rain and overcast skies, we are not going to experience extreme cold. Something that agrees with what the AEMET pointed out when seeing that we have been there for three years (for now) without a great cold wave throughout Spain. That is why normal temperatures or slightly above the historical average are expected, and without severe frosts. This is because the Atlantic air flow, being oceanic and humid, usually tempers the environment, avoiding the drastic drops in thermometers typical of continental or Siberian air inlets. In the long term. These predictions are made with the ECMWF models with their weekly maps and clearly show the persistence of low pressures surrounding the peninsula until the middle of the month. But in the long term everything can end up changing and give a very different prognosis. Although it is true that combining it with ICON and other global models reinforces the instability forecast, which increases the reliability of this prediction throughout the month of February.

The train of storms that threatens Spain is just the beginning of the problem

by

What is happening? What is going to happen? As I write these lines, nine autonomous communities they have yellow notices due to rain, wind and other coastal phenomena. And the reason, as we have been repeating for the last few days, is a “train” of fronts that comes directly from the bowels of the Atlantic and will cross the peninsula. The forecast, in data. The models are beginning to converge and the forecasts are quite clear: Waves of up to five meters on the Cantabrian coast and off the coast of Galicia. Winds will easily reach 61 kilometers per hour. No particularly intense rains are expected in the coming days (the peak may be 15 l/m2 in areas of Huelva and Cádiz). Although, yes, those accumulated in Galicia, Zamora, Ávila and Cáceres may be important — above all, in a context of saturated soils. The winds, for their part, will be above 70 kilometers per hour throughout the north of the peninsula. And, with these figures, why is it important? Because of what is known as ‘multiplier risk’: we are not going to face any peak of intense rain, but the recurrence of fronts will increase operational risks. It is the meteorological equivalent of a ‘calabobos’: it seems that it does not get wet, but it ends up with half of Spain completely soaked. The only question is whether an effective “atmospheric river” is formed (or not). That is, if the humid and warm air from the Gulf of Mexico integrates into one of these fronts and a greater blow is produced. A “normal” circulation in an “abnormal” context. Because, as it is worth remembering, the cold days of recent weeks are beginning to not be normal on the peninsula. And, although this relatively active western circulation is, the arrival of successive fronts complicates the situation: there is a lot of water accumulated in the form of snow. So we go back to normal. A normality that is summarized in waiting to see how long it takes for the storm corridor to close and waiting for the swamps to continue filling. Summer will be here sooner than it seems. Image | ECMWF In Xataka | While the snow devours half of Europe, there is a place where it is 27ºC and on the beach in the middle of January: Greece

AEMET knows that what is coming is not just a train of storms, it is a ‘master class’ on how winter works in Spain today

by

This beginning of December comes with a train of Atlantic storms, several cold fronts in a row, snow, wind and a lot of sudden thermal changes. But it goes much further than all this: what we are going to see is a perfect example of how winter in Spain works today (in the midst of the climate crisis). What is going to happen? The quick summary is that the start of December 2025 in Spain will be marked by a very active Atlantic circulation. And that takes the form of a “squall train” that will cross the Peninsula during the first 10 days of the month. The most immediate will be a cold front that will leave abundant rains in Galicia and the Cantabrian Sea (with local accumulations of up to 50 l/m²), snow above 1000 meters and strong gusts of wind on the coast. But, as I say, it is the first of at least four. The reign of the negative NAO. We said it a few days ago, the European Weather Forecast Center pointed because the first days of the month we were going to be in negative NAO. The ‘NAO’ is the ‘North Atlantic Oscillation‘ is what meteorologists call the relentless fight between the Azores anticyclone and the Icelandic low, the two great atmospheric phenomena that govern the meteorology of the North Atlantic. When the index we use to “measure who is winning” is negative, the Azores anticyclone is weaker than normal and, for this reason, it cannot block deep Atlantic storms. The direct consequence is that they circulate further south than normal: right at our latitude. This is exactly what is happening. For this reason (and as a novelty) “squall train” is not a funny journalistic metaphor: there are four very active fronts heading towards Spain. And it goes without saying that this is good news: we are coming from very dry and irregular autumns and, despite the cushion of dammed water that we havea phenomenon of this type is going to be really good for us. It remains to be seen if we will be able to take advantage of the rainfall that will arrive. Why do I say this is “a perfect example of how it works today (in the middle of the climate crisis) winter”? Because although the pattern of “chained storms” is classic of the Atlantic winter, these dynamics are encountering a warmer basal situation: the atlantic ocean and the Mediterranean Sea is warmer (and therefore have more energy). It’s “business as usual”, but at higher speeds. In this situation, in fact, a scenario is feared for Europe in which there is less rain in summer in the Mediterranean and more episodes of extreme rain in the cold seasons. This feeling that everything is very similar to the same as always, but in a completely different way, is very strange.

Mediterranean countries seemed ideal for solar panels. Until the dust storms arrived

by

The Mediterranean has always been seen as a privileged land for solar energy: abundant sun, large extensions and A clear commitment to renewables. However, two factors that come from the south and of the climate change are putting this equation in check: the dust storms of the Sahara and the sustained increase in temperatures. The short. A new study warns that Sahara dust can reduce solar production in southern Europe by up to 50 %. Work, Posted in Renewable Energy magazine By the Hun-Ren Research Center of Astronomy and Earth Sciences of Hungary, analyzes the episodes between 2019 and 2023 in Portugal, Spain, France, Italy and Greece. More in depth. To reach these conclusions, the scientists resorted to a data arsenal: the forecasts of the European Network of Transport Systems Operators (ETSO-E), NASA MERRA-2 reanalysis, the European database Copernicus Cams V4.6 and satellite cloud and aerosols. Thus they were able to evaluate time and daily how dust alters solar irradiance and, therefore, the ability of panels to produce electricity. The additional finding is worrying: the current photovoltaic forecasts for the next day usually fail. In Spain and Portugal they tend to underestimate the real loss of energy (up to 15% less than expected), while in Italy and Greece the opposite occurs, with overestimations of up to 10%. A problem that aggravates. Saharan dust is not a new phenomenon, but climate change is intensifying both its frequency and its reach. And Spain, as a study of the Polytechnic University of Catalonia (UPC) warns collected in Xatakait is a true “hot point” of European warming. In the last 50 years, temperatures have increased 3.27ºC in the Iberian Peninsula and the Balearic Islands, more than double the Mediterranean mean. Summer has extended 36 days, rainfall has decreased almost 20% and desertification advances by regions such as Murcia, Almería or Alicante. The scenario for 2050 is a country with steppe or even almost desert climate in much of its territory. If Spain becomes a warmer and more dry desert, dust storms will be more frequent and its impact on even greater solar energy. Is there a possible solution? Until now, the great enemy of conventional solar panels was not only dust, but also heat. As we have developed in Xatakafor each degree above 25ºC, traditional plaques lose between 0.05% and 0.34% efficiency, which can translate into falls from 10 to 25% in very hot days. But a recent study by Laughborough University proposes a script turn: The so -called photoelectocrochemical flow cells (PEC). This experimental technology not only supports heat, but takes advantage of it, with an optimal point around 45ºC. In addition, it does not require active cooling, which lowers installation and maintenance costs. In parallel, startups like the Australian Coolsheet They are developing Passive cooling hybrid systems that cool the panels and, at the same time, heat water for industrial or domestic use. Every 10º less on the plate can be 4% more electrical efficiency. Beyond the results. The research is not limited to more solar panels, but that It must be integrated In the new photovoltaic, more forecast of dust effects, improve real -time monitoring and design technologies that convert heat and extreme conditions into allies, not enemies. Spain and the Mediterranean advance towards a scenario in which the sun will be more abundant, but also more hostile. The future of solar energy is to accept this paradox: it is not just about installing panels, but of adapting them to a changing climate, full of dust, heat and drought. Scientific research, technological innovation and political planning must go hand in hand so that the sun remains the solution, and does not become part of the problem.

We needed more than ever a way of predicting better storms and hurricanes. AI has solved the problem

by

Among the areas in which Google Deepmind works, Meteorological prediction It is one of the most precision is obtaining thanks to the refinement of artificial intelligence tools designed for it. And the company has just demonstrated that AI can overcome traditional methods in hurricane prediction. And is that your model Weather Lab managed to forecast more accurately The trajectory and intensity of Hurricane Erinwhich went from tropical storm to Category 5 in less than 24 hours A few days ago. The first real exam. Until now, the meteorological models were a promise. Hurricane Erin became the first real -time fire test for the Google system. During the first three critical prediction, the artificial intelligence model exceeded the official forecast so much of the National Center for American Hurricanes such as several traditional physical models, including the most reliable Europeans and American. How it works. Traditional models are based on complex physical equations that recreate current atmospheric conditions: humidity, pressure, temperature. Google’s approach It is radically different. Its AI has been trained with a massive data set that includes historical weather information of the entire land and a specialized database with details of almost 5,000 cyclones observed during the last 45 years. “They match these long historical data with details about how hurricanes behave and statistically combine them to see patterns that the human eye could not detect,” Explain James Franklin, former head of the Hurricane Specialists Unit of the National Hurricane Center. Why does it matter so much. The precise prediction of hurricanes is vital to know what type of measures are needed to protect themselves from them in case of emergencies. The three to five forecast days are crucial to make decisions about evacuations and preparation measures. In Google’s internal tests With storms of 2023 and 2024, its model managed to predict the final location of the cyclones with about 140 kilometers more precision than the European model (ECMWF), considered the most exact available. Exceptional performance. Franklin stands out The performance of the Google system: “It really surpassed the other guides in terms of intensity. It captured the general form of the change of the life cycle almost exactly. practically without error.” The model not only succeeded in the trajectory, but predicted with surprising precision how Erin’s intensity would evolve throughout his life cycle. Still in development. Despite success, the Google model is not ready for public use. Weather Lab includes a warning that recommends trusting the official forecasts of the National Hurricane Center. However, Franklin It is optimistic About the future: “For next year, you will receive a very serious look and will really play a role in the forecasts that leave the Hurricane Center.” Cover image | Brian McGowan In Xataka | It is no longer necessary to pay to transform our photos into what we want.

Solar storms are increasingly threatening for the earth. NASA wants to prepare with a “digital twin” of the sun

by

The sun, that star that gives us life, also has an unpredictable character and potentially destructive. So much so that A large solar storm It could return to us technologically to the stone age in the blink of an eye. To avoid this, NASA and IBM They have joined forces To create a model that simulates the behavior of the sun. And how could it be otherwise, it has been generated with artificial intelligence. A authentic twin of the sun to understand it better. The union of forces of these two institutions has resulted in the creation of Surya, an artificial intelligence Designed to act as a digital twin of the sun and anticipate their violent outbursts with precision that with the models that are currently used cannot be achieved. Training an AI with the heart of a star. The challenge of predicting the space climate is undoubtedly a great challenge For scientists. To build Surya, the engineers turned to an inexhaustible data source: the Solar Dynamics Observatory (SDO) NASA Hala. For nine years, this probe has State watching the sun without restcapturing images of very high resolution every 12 seconds in different wavelengths and measuring its complex magnetic field. Once you have all this information is where artificial intelligence comes into action to be able to organize and interpret them for experts. That is why the first thing Surya did is standardize all data formats to be able to process them together. Intelligent filtering of all this information. Once the data was unified, the next step was to use a long -range vision transformer, an architecture capable of analyzing gigantic images to identify patterns and relationships between points of solar activity, regardless of how far they are from each other. But he did not stay here, because thanks to a mechanism known as ‘spectral door’, the system was able to filter the ‘noise’ of the data to reduce memory use and improve the quality of the information with which it worked. Therefore, researchers were removed a lot of work to have to label all the images, causing it to adapt rapidly. More precision and twice as much time to react. The results of the initial tests are very promising. Until now, Traditional models barely gave us an hour in advance before a solar eruption. With Surya it has been shown to be able to launch a reliable warning two hours in advance, doubleing the humanity preparation window. But it is not only faster, but also accurate. The IBM and NASA team recorded a 16% improvement in precision when classifying solar rashes compared to the models used right now. Something that is also thanks to the ability to integrate information from other missions such as Parker solar probe or the Soho Observatory. An open tool for the science of the future. Far from saving this powerful tool in a key drawer, IBM and NASA have made it available to the entire scientific community. Surya is now available on platforms such as Hugging Face, GITHUB or even the Terratorch library. Kevin Murphy, NASA scientific data director, is clear: “We facilitate the analysis of the complexity of our star’s behavior with unprecedented speed and precision. This opens the door to a better understanding of the impact of solar activity on the systems on which our daily life depends.” The goal is for the Earth to be prepared. Although we see the central star of our system as harmless, the reality is that at any time this sensation can change. In this way, preparation and anticipation is fundamental and for the moment all hopes are put in this model of where it is possible to learn from the processes behind the evolution of the sun with the aim of having a greater amount of information.

In the heat and extreme summer storms in Menorca, Aemet has just added one more risk: “Meteotsunamis”

by

A trough travels the peninsula and, like The experts advancedtheir impacts begin to be noticed today. These impacts have led to the State Meteorology Agency (Aemet) to issue various notices, Among them one focused on the risk of Rissagasthe phenomenon also known as “Meteotsunami”. Notice by Rissagas. In addition to the notices for rains and storms (which bind to notices still in force for temperatures of more than 36º in areas of Albacete and Murcia), Aemet has issued various coastal notices that will remain active during the next few days in the Mediterranean, specifically in Catalonia and Balearic Islands. Among these notices is an active one on the coast of the island of Menorca, since there are expected sea level oscillations that could reach 0.7 meters. This oscillation of the island region responds in the Balearic Islands At the end Rissagabut it is also usually called “Meteotsunami” for presenting some parallelism with the seismic phenomenon. Rissagas or meteotsunamis. As we pointed out before, the Rissagas They are abrupt oscillations of sea level. As explained some time ago Aemet’s then territorial delegate in Illes Balears, Mª José Guerrero, these phenomena occur only in coves and ports “with a certain geometry.” As with the tsunamis, these begin with the sea by backward, which can leave the small boats of the fishing and sports ports stranded. In a matter of minutes, the waters return to the port, and do so with a flood that can drag the vessels and overflow the docks. On average, these oscillations are usually about 50 centimeters. However, cases have been found in which they reached several meters. “Tsunamis“Meteorological. As its name suggests, the “Meteotsunami” differs from a tsunami in his Meteorological origin and not seismic. According to Aemetthese phenomena are produced by “small although sudden changes in atmospheric pressure (1-3 hectopascal) derived from the passage of fronts, gravitational waves, turbonada lines and in general phenomena associated with convection.” First red notice of Aemet. The forecasts speak of significant impacts beyond the risks on the coast. Aemet’s forecasts They alert today “showers and storms with a probability of being strong, even locally very strong”, which will affect large areas of Catalonia, Pyrenees, northern zone of the Valencian Community and east of the Iberian system. Tomorrow these showers and storms are expected to affect both the Mediterranean coast of the peninsula and the Balearic Islands themselves. Thus, the agency has issued notices of different categories distributed throughout the center and northern Mediterranean slope and the Balearic Islands. Today’s notices include a red notice (extreme risk) due to rains in the central depression of Barcelona. In that area, up to 60 mm of rainfall could be accumulated in one hour and up to 120 mm in a matter of three or four hours. Waiting for a change. In addition to the red notice due to extreme risk, the agency maintains various orange notices (for important risk) during today’s and tomorrow, both for rains and storms. The situation is expected Start to appease on Fridayalthough some episodes torments are expected to continue during that day.

A trough ready to free us from the scorching heat, but charging its price on storms

by

The worst of this warm episode has not yet arrived but there are those who already have their view at its end. It is not for less, as it is customary this summer, the only thing that is helping to reduce the thermometers is the arrival of storms. And again meteorologists foresee them. Change the trend. On Friday part of the peninsula will see A new transition Meteorological: The heat episode we now live will give way to storms. These stormy episodes will affect the north third and could be strong, leaving winds of intensity and hail. Dorsal and trough. Again, the alternation between scorching heat and intense storms is given by the succession of dorsal and trough, air masses in height under the influence of high and low pressures respectively. According to explains the geographer Samuel Biener in Meteoredthe change in the situation will come from the hand of an Atlantic trough driven in turn by the undulations of the stream in jet. Two seas to red live. There is another important element in the risk that these storms suppose in summer, Remember too Biener himself. It is in the seas, and more specifically in the temperature of its surface waters. Both the Western Mediterranean and the Eastern Cantabrian They are suffering their own “heat waves”. The waters of the surface in these regions have been accumulating several degrees above what would correspond to this time of year. This increases the risk of convective storms. Heat and moisture are transmitted to the air on the surface and then this air interacts with possible cold and dry air masses such as those dragged by the rush that approaches, generating important storms that discharge the humidity and energy accumulated in the environment. Uncertainty, for now. There is still uncertainty about the evolution of this new episode of storms but The forecasts From the State Meteorology Agency (Aemet), on Friday both cloudy skies are expected and “locally with a storm” rainfall. These will circulate from the west and will end up affecting most of the north third, being especially intense in the Eastern Cantabrian and Western Pyrenees. The situation is expected to refer towards the afternoon of Saturday, although the forecasts indicate the possibility that during the day there will be “strong and accompanied by storm” rainfall between the Eastern Cantabrian and the Northeast of Catalonia. For now the agency has not issued any warning related to these storms, but it is still early to rule out a worsening of the situation.

What are solar storms and why society has become so vulnerable to something that has happened millions of years

by

“Understanding the space climate is not an option.” With this lapidary phrase summarizes its efforts to predict solar storms the European Space Agency. They occur since the sun exists, and some of the most powerful They are recorded in the trees rings. But they are not our ancestors, but we, the most dependent civilization of the technology that the earth has ever stepped on, the most vulnerable to them. But what exactly are solar storms? How are these energy outbreaks? And the million dollar question: can we predict when the next one will impact on earth? The answer is in a complex network of satellites, artificial intelligence models and constant surveillance of our star by space agencies. What is a solar storm 150 million kilometers away, the sun flushes with a magnetic activity so powerful that, from time to time, it goes out of hand. A solar storm is a sudden explosion of energy, plasma particles and magnetic fields that the sun releases towards the solar system. If the ejection occurs in the direction of the Earth, the solar storms can produce more intense auroraslike those that were seen in much of the world in May 2024. But they are not only a show: in our technological civilization, they are also a threat. To understand them, we have to differentiate their two main components. The guts or solar flares. They are a intense radiation outbreak: A whip of energy released when the magnetic fields of the sun tense and break. This radiation travels at the speed of light, reaching the earth in just eight minutes. They are classified according to their intensity by X -ray flow, measured in watts per square meter. The class A, B and C are the weakest, and those of class M and X, the most powerful, which usually cause interference in short wave radio communications. Coronal mass ejections. It is the ballistic part of the solar storms. While fulguration is the flash, the coronal mass ejections They are the “cannon bullet”: a gigantic bubble of loaded particles (plasma) and magnetic fields that are thrown into the space at speeds of millions of kilometers per hour. This massive cloud of solar material It takes between 18 hours and a couple of days in crossing the space to cross with our planet. Not all guts are accompanied by a coronal mass ejection, but when they occur together and in the direction of the earth, they are a powerful cocktail that can put astronauts at risk, knock down satellites (as happened during a Starlink deploymentor fry electrical installations on land (As in the Carrington event). How they form A Class M. Image: That The origin of the solar storms is the magnetic field of the Sun. A star is not a solid ball, but a sphere of rotation plasma. But it does not rotate uniformly: his Ecuador turns faster than his poles. This differential causes the magnetic field lines to twist, tangle and accumulate an enormous amount of energy, as if they were elastic gums twisted to the limit. These areas of intense and complex magnetic activity They usually manifest as sun spots on the visible surface of the sun. When the accumulated tension becomes unsustainable, there is a magnetic reconnection event: the lines are broken and violently reorganized, suddenly releasing all the stored energy. This release drives the guts and can launch into the mass of the solar crown. The intensity of its effects on Earth depends on its speed, its size and, above all, the orientation of its magnetic field. If the magnetic field of coronal mass ejection is oriented towards the south, it is aligned in opposition to that of the Earth, our protective shield, which allows a much more efficient and destructive energy transfer. How they affect the earth If we are here it is because the magnetic field and the atmosphere of the earth protect us from radiation. Solar storms are not a direct risk to the health of living beings on the earth’s surface. For astronauts it is another song. In 1972, shortly before the Apollo 17 mission, there was an intense solar storm that would have inoculated a mortal amount of radiation in astronauts if they had been on the surface of the moon. Today, astronauts who work in the low land orbit, even protected by the magnetic field, plan space walks according to the space climate. The really vulnerable to intense solar storms is our technological infrastructure. When a coronal mass ejection impacts the earth’s magnetosphere There is a geomagnetic storm. Extreme cases can induce electric currents in high voltage lines, overloading transformers and raising the risk of blackouts, especially now in summer, when the electricity grid is already very tension. The satellites, despite having mechanisms to avoid induced currents, usually carry the worst part. Solar storms expand the upper atmosphere of the Earth, increasing friction and accelerating the fall of satellites that orbit the earth at low height. This effect already is accelerating the fall of Starlink satellitesthe most large constellation of the low orbit. Even during moderate geomagnetic storms we can notice some effects, such as precision errors in GPS systems or that airlines deflect flights from polar routes to avoid failures in plane systems and protect passengers. The kind face of solar storms are the auroras: solar particles that when hitting our atmosphere They create a light show at the poles. During severe geomagnetic storms, dawn can also be seen in less common latitudes. When the next solar storm will occur Image: that The most severe geomagnetic storms occur Around solarthe period of more activity of the Sun in its 11 -year cycle. Now we are going through solar cycle 25, and we approach the maximum activity, planned by the NOAA and ESA by the end of 2025 or early 2026. This means that we are in a high probability phase of intense storms. Luckily, spatial meteorology is advancing by giant steps. To predict solar storms, … Read more

Aemet indicates that we will touch the 43rd to orange notices for storms

by

In Sunday afternoon, locations such as Morón de la Frontera (Sevilla) or Montoro (Córdoba) saw their thermometers to place On the edge of the 43rd Celsius. Although high temperatures are not going to disappear so quickly, the phenomenon that experts are now worried is A week of change. Meteorologists foresee A new change Meteorological this week, one that will not only bring us a drop in temperatures: the models warn of the arrival of storms that could be intense. As if that were not enough, hail could also make an appearance. What is happening? Since the end of last month, the meteorological sway was marked by the succession of several dorsal and a trough. The former brought us atmospheric stability and high temperatures, the last one brought us rainfall and a brief relief of heat. However, the fresco is not going to bring a new trough, Experts warn: It will be an isolated depression at high levels, a Dana. Although it is expected that as of today the storms begin to demonstrate in the north, the effects of this Dana will be especially notorious in Galicia from the day of Tuesday. From heat to storms. According to The forecasts From the State Meteorology Agency (Aemet), the storms will have the probability of being strong and arriving accompanied by both hail and “very strong” gusts in some areas of the plateau, Eastern Betic System and in the Iberian South. The agency has activated various notices For storms in these areas, oranges in the case of the province of Teruel for “very strong hail probability and very strong wind gusts.” On Wednesday, “strong” storms are also expected in the northern half, with probable showers in western Galicia, Cantabrian environment, Alto Ebro, the Iberian and the Pyrenees. Aemet storm notices will be activated in most of the Peninsular Northern area, with orange notices in areas of the Basque Country and Catalonia. Not far from 40º. Despite the decrease in temperatures, storms will coexist with heat. So much so that weather notices for rains and storms will coexist these days with notices due to extreme temperatures above 37º. Aemet has also activated An orange alert on Tuesday on the Ebro banks in Zaragoza due to maximum temperatures of up to 39º.
