Spain Prepares for Heavy Rainfall as New Weather System Approaches Mediterranean Coast

Spain is on alert in multiple regions, anticipating a new weather front that is forecast to deliver torrential rainfall and cooler temperatures, following flash floods that caused widespread devastation in the eastern part of the country two weeks prior. The eastern and southern Mediterranean regions are once more identified as the most susceptible. Aemet, Spain’s meteorological agency, has issued an orange alert for sections of the Valencia, Catalonia, and Andalusia regions, along with the Balearic Islands, effective immediately until Thursday. Aemet has issued a warning that the expected rainfall and storms could be “very strong to torrential”. This orange alert, which is the second-highest level, indicates a significant meteorological event that carries “a degree of danger for normal activities”. A military vehicle has been observed traversing towns, utilizing a megaphone to broadcast warnings about the impending storms. In numerous areas of Valencia, precautionary measures are being implemented, including the suspension of school classes and sports activities in certain towns, and the placement of sandbags to safeguard the center of Aldaia. Nevertheless, this second “Dana” weather system is not anticipated to be as severe as the red alert issued on 29 October, when the Valencia region experienced an unprecedented toll in terms of lives lost and material damage. The flooding in Spain last month resulted in 222 confirmed fatalities, with an additional 23 individuals still unaccounted for. Dana weather systems develop when a low-pressure zone becomes “cut off” from the primary current of the jet stream. Consequently, instead of traversing a region with relative speed, these systems become stationary over the same location, leading to prolonged rainfall over several days. The interaction of colder air at high altitudes with warmer air originating from the Mediterranean further intensifies the storm. Significant rainfall has already affected certain areas this week. On Monday night, sections of Almería province in Andalusia experienced flooding, leading to the temporary closure of a portion of the A7 motorway. Emergency services successfully rescued three individuals whose vehicles had been swept by floodwaters to a bridge in the town of Vícar. The Spanish weather agency has recommended that individuals in regions under an orange alert avoid ravines and waterways, even if they appear dry, due to the potential for sudden flooding. Furthermore, the national traffic office (DGT) advised residents in these areas to verify road conditions prior to operating vehicles. King Felipe VI was scheduled to visit a military base in Bétera, Valencia, on Tuesday, where armed forces personnel are engaged in the continuing search for missing individuals and the clean-up efforts. During an earlier visit to Valencia, King Felipe VI, Prime Minister Pedro Sánchez, and regional president Carlos Mazón encountered insults, jostling, and had mud thrown at them by residents in the town of Paiporta, stemming from a perceived inadequacy of state assistance following the tragedy. Mazón, specifically, has faced increasing scrutiny regarding his administration’s actions on the day the flash floods occurred. Dana weather systems are a regular occurrence in Spain, typically manifesting approximately 10 to 20 times annually in the western Mediterranean. This particular Dana, the second within a few weeks, is not regarded as being as extreme or as slow-moving as the system that impacted Valencia at the close of October. Nevertheless, the regions expected to receive the most precipitation, particularly near Malaga and Granada, could experience approximately 180mm of rain this week, which equates to about two months’ worth of rainfall concentrated over several days. Large hail and squally winds are also identified as potential hazards. The season’s initial significant snowfall is anticipated to impact the Cantabrian mountains, the Sierra Morena mountains, and the Central and Betic chains, as colder air traverses the Peninsula. Strong, gusty winds are also expected to accompany the snowfall in these mountainous areas.
