We have been hearing talk for days about the “storm of the century”, this is what AEMET says about it (and about the trend of fattening meteorological headlines)

It’s curious. A “storm of the century” concept has been around for days and, in the last hoursa date has even been set: February 25 would be the moment in which the storm would reach the country’s coasts. And I say that all this is curious because, in short, it is inaccurate, a ‘journalistic hook’: a lie after all. This 25th changes time, yes. But what the models describe is more like an Atlantic front (with rain in Galicia and some instability in the Canary Islands), than a truly exceptional episode. But let’s take a look because there are more things to take into account. What do the models say? That is the big question: AEMET and the rest of the specialized media draw a very different scenario. Galicia stands out with relevant accumulations (we are talking about 20–40 l/m² in the area from A Coruña to Pontevedra), but little else: in the rest of the areas where it rains, the quantities are much more discreet. In most places, almost testimonials. On the other hand, it is also possible that it will rain in the Canary Islands, but (unlike the peninsula) it will be a DANA in Morocco. And then? So, nothing. We won’t have big announcements; neither by winds, nor by rain, nor by coastal problems. AEMET is worriedYeah; but due to the persistent rainfall that may accumulate in the northwest. For the rest, if there is any news on the table, it is that a phenomenon that has been somewhat missing is going to return: the haze. There will be no “storm of the century” and that, of course, is excellent news. After all, we come from a winter that has been nothing more than a huge chain of storms. This has led to a whole process of social desensitization that is forcing popular meteorological information to raise the threshold until it borders on (or settles into) sensationalism. And it’s not the best time to do it: as AEMET itself points outit is possible that we are approaching a new era of precipitation in Spain. Climate change is increasing precipitation extremes globally. It doesn’t seem like a good idea to play ‘Peter and the Wolf’ just when things are starting to change.

The meteorological winter has already begun for the AEMET. And now we have another problem with the DGT beacons

The State Meteorological Agency (AEMET) has not waited for the solstice to start winter. A season that, meteorologically speaking, extends from December 1 to February 28. Three months of cold await us (although less and less)rain, snow and various inclemencies. This year, it is inevitable to ask ourselves if the cold may affect the V16 beacons of the DGT. The answer is a resounding yes. Resistance up to -10ºC. All approved V16 beacons must have with a series of requirements. And one of them talks precisely about resistance. There are two things to keep in mind here: the IP rating and what temperature range they can operate in. New connected beacons must have at least IP54 certification. That is, resistance to dust and splashes of water. But they must also offer adequate operation within a wide range of temperatures. Specifically, between -10ºC and 50ºC. It is enough even If we leave the car in full sun in summerbut in winter it gets a little more complicated. BUT. Theoretically, Spain is not a very cold country. But although it is not at the level of the Nordic countries, in certain places or times the thermometer can fall below -10ºC. If we are going skiing, if we are driving on a mountain road on a particularly cold day or if we are considering a getaway to one of the “refrigerators from Spain”things get complicated. For example, Molina de Aragón (Guadalajara) is considered the coldest town in Spain and has the milestone of having reached -28.2 degrees. In these types of places and situations, the resistance to -10ºC of the beacons is insufficient, so their connectivity may stop working, thus losing virtual visibility, or even fail to turn on. Another problem: snow. Beyond the problems caused by extreme temperatures, there is another phenomenon that in the winter season can interfere with the beacons. Much has been said about the visibility problems of these devices in broad daylight, in fog or on very tight curves, but snow can also become another obstacle. Beacons should be placed on the highest part of the vehicle where possible, usually the roof. If the snow settles, it can cover it and thus kill the physical visibility it provides us. The alternative. The V16 beacons aim to improve safety on the roads, warning other drivers of the obstacle posed by a car stopped on them. In the event that the beacon does not work due to problems with temperatures or snow, the option left is to contact the emergency services via mobile phone. The V16 beacons, which will be mandatory from January 1, 2026, are not without controversy. From the scams around them until accusations from groups of the Civil Guardthe DGT He had to admit his mistakes and has already explained that will be flexible with fines.

Meteorological forecasts are a private preserve. A new AI model wants to democratize the prediction of time

A group of researchers has just raised a most striking option: democratize meteorology. Your new weather prediction system challenges traditional systems, very expensive in computational resourcesand make use of AI so that (almost) any of us can become a meteorologist who performs his own personalized predictions. Aardvark Weather. This is the name of a new system of weather predictions that according to those responsible will make any researcher with a desktop PC in a full -fledged meteorologist. The system makes use of AI algorithms and raises an alternative to the conventional systems they use thousands of times more computing capacity. Homemade predictions. The normal thing is that a weather forecast platform takes several hours to process a prognosis. For this, it also needs supercomputers and a team of experts who develop, maintain and display those forecast systems. Aardvark Weather allows you to train an AI model with data from Meteorological stationssatellites, ships or airplanes worldwide and then make predictions based on that data. The investigation. The study Published in Nature this week comes from a group of researchers from the University of Cambridge, the Alan Turing Institute, Microsoft Research and the European Center for Medium-Russian Weather Forecasts (ECMWF). In it they explain how the numerical weather prediction (NWP) is being replaced For automatic learning and neuronal networks that allow “improving the speed and precision” of the prediction. Hyperlocalized forecasts. Among other things the system would allow to offer hyperlocalized forecasts and adapted to specific industries. Richard Turner, automatic learning professor at the University of Cambridge, explained In The Guardian how this model could be used to predict temperatures for agricultural crops in areas of Africa or The wind speeds For a renewable energy company in Europe. The time in the next eight days. Turner adds that the model could be able to generate precise forecasts for a range of up to eight days in the future, when it is normal for precise forecasts to only be guaranteed to five days. Rapid. This system is capable of generating a complete forecast from observational data in a second when processing it in four NVIDIA A100 GPUS, when 1,000 hours-nodo is normally taken in the HRES model of the ECMWF. Ideal for developing countries. There are regions in which these types of forecasts are especially important, and having a “personalized” system would be very useful. Aardvark Weather offers that option according to its creators, because both its implementation and its use is much more accessible. Previous attempts. At the end of 2023 Deepmind precisely Graphcast announceda meteorological prediction system based on AI that had an operation up to 1,000 times cheaper in energy consumption. Its precision was in fact greater than the best of current systems, but it does not seem that development has been implemented in practice. A few months ago Deepmind researchers presented their evolution, called Gencastanother prediction based on automatic learning that improved its predecessor and that of course competes with Aardvark Weather. Everything therefore points to this type of systems are gaining ground and interest, but remains to be seen if they apply massively.

Winter storm spreads across southern US with ice and snow

NEW ORLEANS— A massive storm of snow, sleet and freezing rain hit the southern United States on Wednesday, setting new records for snowfall and exposing the region to unaccustomed winter joys and dangers. From Texas and extending south to Florida and the North Carolina coast, snow and sleet caused ice accumulation in cities New Orleans, Atlanta and Jacksonville, Florida. In Alabama, the weight of the snow caused the dome of the Mobile Civic Center to collapse, which is scheduled for demolition to make way for a new arena for sporting events. At least eight deaths were attributed to the storm as temperatures settled below freezing with even colder wind chills. The arctic air also turned much of the north-central and eastern parts of the country into a freezer, causing hundreds of flights to be cancelled. Government offices remained closed, as did classrooms for more than a million students who are more accustomed to hurricane evacuations than snow days. New Englanders know what to do on days like these: Terry Fraser of Cape Cod, Massachusetts, didn’t have his windshield snow removal tool with him when he went out to visit his granddaughter in Brunswick, Georgia, so he used the card from a discount store to remove snow and ice from his rental van in a frozen hotel parking lot. “This is what we do up north when you don’t have a scraper,” Fraser said. “Hey, it works.” In Tallahassee, Florida, the Holmes family set their alarms for the early hours of Wednesday and headed out in search of a snow-covered slope before it melted. Layla, 9, and Rawley, 12, used what they had: their surfboards. “You have to be creative in Florida!” said mom, Alicia Holmes. Anchorage wants its snow backThe record 10 inches (25 centimeters) of snowfall in New Orleans more than doubled the snowfall Anchorage, Alaska, has received since early December, the National Weather Service said. “We would like our snow back,” the weather service office in Anchorage joked in a post on the social network X. “Or at least some King Cake in return.” Anchorage was also warmer Wednesday morning than New Orleans, Atlanta, Jacksonville or Charlotte, North Carolina, according to the weather service. Dangerously cold temperatures and wind chills are forecast to persist in the southern region of the country on Thursday morning, with widespread frost in some places through the weekend, the weather service said. The thermometer is expected to return above freezing on Thursday in places such as New Orleans, and by Friday in Tallahassee and the coast of the Carolinas. Interstate highway closures Snow and ice also forced road closures, including a several-mile stretch of Interstate 10. Causeways and bridges crossing the Louisiana marshes were particularly prone to frost. “Louisiana, if you can, just hang in there,” Gov. Jeff Landry said, warning that Tuesday’s “magical” snow day would turn dangerous Wednesday as conditions worsened. In Charleston, South Carolina, it took crews nearly 16 hours to reopen traffic along the massive 2.5-mile (4-kilometer) Ravenel Bridge, which carries about 100,000 vehicles a day. Icy conditions plagued drivers in Georgia, where authorities responded to more than 1,000 calls for help. Who needs a beach when there’s snow?Some people took advantage of the Ravenel Bridge’s steep overpasses and turned them into makeshift sledding tracks. On the Outer Banks, children slid down snow-covered sand dunes near where the Wright Brothers made their first flight, while adults attempted to navigate waist-deep drifts of snow at Kitty’s Pier. Hawk. One ferry system suspended service between the barrier islands. “Maybe every 10 years we get a good snowfall like this,” said Ryan Thibodeau, 38, co-owner of Carolina Designs Realty, a vacation rental company. The storm that triggered the first blizzard warnings for some locations along the Texas and Louisiana coast also blanketed the beaches of Gulf Shores, Alabama, and Pensacola Beach, Florida. Snow covering the South Carolina sand from Hilton Head to Myrtle Beach created more opportunities to convert surf gear into sleds. “It didn’t have the speed of a sled,” Alex Spiotta said as his family rode a boogie board on the Isle of Palms, South Carolina. “But in the south, you have to use whatever you have.” Other things that were used as sleds were: a laundry basket in Montgomery, Alabama; a pool tube in Houston; and kayaks, cardboard boxes and alligator inflatables on the Mississippi River levees in Louisiana. A vehicle was dragging a skier down a street in Pensacola, Florida. In Metairie, Louisiana, several nuns were having fun throwing snowballs at a priest. Flight cancellations and fatalitiesNearly 2,000 flights were canceled in the United States and another 2,300 were postponed as of midday Wednesday, according to the website FlightAware.com. The unprecedented demand for electricity to stay warm was met by the Tennessee Valley Authority, which provides power to more than 10 million customers in seven states, and PJM Interconnection, which operates the 13-state grid. But more than 100,000 families were without power in the Mid-Atlantic region Wednesday morning, according to the website PowerOutage.us. The Texas Department of Safety and Security reported that five people were killed early Tuesday when a tractor-trailer crashed into other vehicles on an icy highway southwest of San Antonio. Two people died from the cold in Austin, Texas, where emergency crews responded to more than a dozen reports of “cold exposure.” In Georgia, authorities said one person died of hypothermia. And yet the planet is warmingIn Southern California, where fires have killed at least 28 people and consumed thousands of homes, Santa Ana winds and arid conditions worsened by climate change continued to raise concerns. Although the United States, which covers approximately 2% of the planet’s land surface, experiences unusually low temperatures, the planet as a whole sets heat records. So far in 2025, the first 20 hottest days of a year on record have been experienced, according to the European climate service Copernicus, leaving last year’s mark behind, according to the data, which goes back to 1940. So far this year, U.S. … Read more
