There is something strange about a storm in Aragón in August. It was hot in the morning, the kind of heavy, still heat that feels like it’s always summer. The sky over Cosuenda turned black around 3 p.m. What began as rain turned into hail in a matter of minutes. Not little hail. Three- to four-centimeter stones, and some that are said to be even bigger, are hitting roofs, cars, and the vineyards that cover a lot of the land around this small town in Zaragoza province.
People in the area talked about how it sounded on the phone, and the story spread on Spanish news sites. “It was almost like missiles hitting the ground,” she said. “Some of them broke apart.” Going outside was very scary. An account like that is easy to brush off as exaggeration, but the pictures that came out afterward—fist-sized chunks of ice picked up from the ground, streets briefly turning white—made the story feel, if anything, understated. The storm didn’t last long. That was enough.
The town of Cariñena, which is not far away, had the same storm happen soon after Cosuenda’s. Adolfo Simón, who is Cariñena’s deputy councilor for agriculture, took a quick walk around after the hail stopped and saw dents in many of the cars on the streets. All of them. He also said that some parts of the vineyard looked “quite damaged,” but he wasn’t ready to make any firm judgments yet because damage assessments were still going on. He agreed that the water that came with the hail might not be completely bad—August is usually dry—but the timing was really bad. Things were just getting ready to harvest that Wednesday.
Farmers in this part of Spain are very familiar with the tension between helping and hurting. The Cariñena wine region is one of the oldest in the country. It makes wine from Garnacha and Cariñena grapes that have been grown there for hundreds of years. It depends on how bad the hail is, how many rows were directly hit, and some luck, but a hailstorm at the start of harvest can ruin a season. No one in the industry wants that kind of uncertainty. It’s still not clear how bad the damage to the vineyard really is.
From a meteorological point of view, the storms were not a surprise. The Spanish weather service, AEMET, had sent out orange alerts for storms, big hail, and strong winds across many areas of Aragón before the weekend. These included the Ribera del Ebro and the Ibérica zaragozana. For the Ribera del Ebro corridor, forecasters had warned of hail that was between two and three centimeters across. It was bigger what fell on Cosuenda. In Spain, orange-level alerts are very important; they don’t happen all the time.
The day before, there was already trouble. A storm caused a tree to fall on the N-240 road near Monzón in Huesca, blocking the road. In Teruel, a rockfall blocked part of the A-1702. During a heavy rainstorm in Híjar, the streets turned into shallow rivers that made it hard to drive. Reports came in from Villadoz, Daroca, and Mainar of damage to roofs, broken car windshields, and branches that fell. Even tho none of them were life-threatening, the overall picture of the region was one of a landscape that had been hit many times over the course of several days.
It was also warned by the Confederación Hidrográfica del Ebro on Sunday that smaller rivers and ravines in the northern Ebro basin, especially in the western and central Pyrenees, could flood quickly. Some places get 15 to 30 liters of rain per square meter in just one hour, and small channels can’t handle the flow fast enough. People were told to keep an eye on official river and weather data and follow civil protection advice. This was standard language, but it means more when the water is already moving quickly.
As we watch the pattern of alerts and storms this summer, we get the sense that these events are getting closer together than in previous years. It’s really hard to tell if that’s because of a change in the number of storms or just more media attention. It’s clear that Aragón has spent a lot of August hopping from one weather alert to the next. Farmers, cities, and road authorities have all been fixing the damage in their own ways. On Monday, more warnings were sent out for Teruel. In some areas, it was expected to rain up to 40 millimeters per hour. It looks like August is still going on in Aragón
