November is a fascinating month from a meteorological point of view: the atmosphere is unstable, and the episodes of rain accompanied by storms are a spectacle for golf enthusiasts and experts. However, there is also a downside, as was evident in Valencia last night.
An astonishing 152 liters per square meter fell in just a few hours., which caused the closure of numerous tunnels, underpasses, and streets. This event became the largest downpour since October 11, 2007, when 178,2 liters per square meter were recorded in the capital of the Turia River.
The storm, which remained static near Valencia, began to move into the community around the afternoon. Around 9 p.m., the intensity of the rain increased significantly, and four hours later, it intensified again, which caused more than half a thousand calls to 112But it didn't just rain; it was also accompanied by an impressive display of hundreds of lightning bolts that lit up the night sky: 429 struck Valencia alone, out of a total of 2703 that struck across the entire Valencian Community, according to data from the State Meteorological Agency (AEMET).
The force of the rains was such that the Emergency Coordination Center decreed the zero situation and the hydrological alert for rains in the Horta Oest region and in the city of Valencia itself. What does a 0 emergency situation entail? It's a warning issued when there's a risk of danger or possible damage, as was the case on this occasion.
Flooded streets and avenues, cars trapped or nearly flooded... Even medical centers suffered serious problems, such as the Hospital Clínico de Valencia, which experienced severe flooding due to the strong torrential rain. For those facing the consequences of the rain, it is essential to know how to act in the event of a strong downpour and be prepared for similar situations.
Despite the intensity of the storm, no deaths or injuries have been reported, which is always good news in the midst of adverse weather conditions. Compared to other storm events in the region, such as the 1957 catastrophe when rains caused massive flooding with over 300 fatalities, this event demonstrated a surprising capacity for emergency management, although infrastructure in some areas was once again tested.
It is interesting to note that the 2024 storm has rekindled the debate about changing climate patterns. Increasingly intense but short-lived rainfall is characteristic of the new meteorological dynamics in the Valencian Community. AEMET warns that, although the annual rainfall volume may remain similar, the distribution has changed, increasing the possibility and severity of episodes of torrential rainThe situation also reminds us of the importance of knowing what is a flood and how it can affect society, especially in critical moments like this.
Waterspouts have also been a phenomenon associated with this series of storms. On the same day, it was reported that a "waterspout" Visible from many coastal towns, including Sueca and Cullera, it was considered the clearest and most impressive image captured on the Valencian coast in the last decade. This atmospheric phenomenon is common during episodes of instability and is caused by a shift in the air accentuated by the storm. It's a good time to review similar cases, such as the spectacular waterspout which has been seen on other occasions near the coast.
The intensity of the rains, meanwhile, has led authorities to take urgent measures. Emergency brigades were mobilized to respond to requests for aid and rescue. However, these efforts were complicated by the flooding of many access roads, which forced traffic restrictions and the need to activate emergency protocols in the face of adversity.
To understand the storm's impact, it's important to monitor rainfall data. According to the Júcar River Basin Authority, rainfall of up to 129,8 liters per square meter was recorded in several locations in Valencia, such as the Blasco Ibáñez area. At Manises Airport, 110,6 liters were reported, giving a clear idea of the magnitude of the phenomenon and the potential for flooding in the region.
Furthermore, for those who have experienced the effects of flooding, it is essential to reflect on how the city can prepare for future climate events. Urban planning and water resource management become crucial in a context where irregular rainfall could become the new norm. It is essential to focus on DANA and its impact on communities, as well as the need to implement infrastructure improvements.
This meteorological event, beyond being a catastrophe, should serve as a reminder of the importance of drainage infrastructure and disaster response capacity. In this sense, history shows us that after every severe event, such as the great flood of 1957, significant changes were implemented that have allowed Valencia to better cope with the impact of similar phenomena and reduce the risk of flooding.
Today, the combination of increased public awareness about climate change and the need to maintain robust infrastructure could help the community adapt to these new realities. Analysis of this storm and its effects is expected to help authorities improve mitigation and response strategies for severe weather events.
The Valencian community is in a moment of reflection, where it is vital to join forces to prevent and mitigate future disasters, thus ensuring safety and quality of life in the region.
