Storm Martinho has begun to cause significant concerns in Madrid, as heavy rains threaten to overflow local rivers and disrupt transportation systems. The storm, which swept the region on March 19, 2025, has prompted authorities to take precautionary measures, especially regarding the Manzanares river.
On March 19, access to the M-40 highway from the M-30 at kilometer 25 was temporarily cut off due to fears of the Manzanares overflowing. Fortunately, this route reopened on March 20; however, officials warn it could close again if the anticipated rains materialize. With the current height of the Manzanares river coming dangerously close to the roadway—within just a few centimeters—authorities remain vigilant.
The Madrid City Council is not only monitoring the Manzanares but also the A-6 highway in the Puerta de Hierro area, which may face significant impacts due to the storm and subsequent reservoir overflow. Inma Sanz, the Delegate of Security and Emergencies for the council, noted during a press conference that "the situation is currently most critical for the Manzanares due to the reservoir releases," bringing ongoing concern for commuters and residents alike.
In the midst of the chaos, a report from the Canal de Isabel II confirms that the Valmayor reservoir is currently at 96% of its capacity. As a response to the rising water levels and incoming rain, it is releasing water at a rate of 40 cubic meters per second to manage the inflow from rainfall and upstream sources. This action aims to relieve the risk of flooding in lower areas of the Aulencia river and maintain overall water management in the region.
As the torrential rains continue, the Community of Madrid has deployed a command post to coordinate emergency responses across the region. The Madrid Community Security and Emergency Agency has urged residents to limit travel until conditions stabilize, emphasizing the need for safety amid the unfolding situation. Current yellow alerts have been issued across various areas, reinforcing the severity of the weather with warnings of further potential flooding.
Moreover, the storm’s impact extends beyond Madrid's borders. In Andalucía, a total of ten roads are closed, mainly in the province of Cádiz, while thirteen residents were evacuated in El Palmar de Troya due to rising waters. Additionally, ferry services between the port of Tarifa and Tangier are suspended, demonstrating the storm's widespread effects.
As heavy winds accompanied by the rains disrupt local air travel, Bilbao experienced the cancellation of sixteen flights, posing a further challenge to travelers in the region. In response to these disruptions, local authorities are working diligently to coordinate efforts to ensure public safety and restore normalcy as soon as the weather permits.
The environment in Madrid and its surroundings is precariously hanging in the balance as the storm continues to unleash its fury. Early reports indicate that the levels in the Manzanares river and the El Pardo dam have slightly decreased compared to the previous day, offering a glimmer of hope, but ongoing rains forecasted for later days may complicate matters.
As the local community prepares to face the full brunt of Storm Martinho, the coordination between the city council and regional water management authorities will be critical in mitigating flooding risks and protecting local citizens. The gravity of the situation necessitates continuous monitoring and quick response actions, especially as Madrid attempts to navigate through these tumultuous weather patterns.
For now, vigilance is key. Authorities encourage all residents and travelers to remain cautious, stay informed about the evolving situation, and heed advice from emergency services, ensuring everyone’s safety as the storm progresses.
