Downpours in Biscay: Up to 12 liters per m² in 10 minutes. Heavy downpours hit Biscay: in Mungia, nearly 12 liters per square meter fell within just 10 minutes. Streets and sewers in Bilbao were flooded. Authorities maintain a yellow alert level.
Heavy rains hit Biscay on Friday afternoon, causing local flooding and disruptions to urban infrastructure. According to Euskalmet, precipitation began around 3:00 p.m. and led to a sharp rise in water levels in several towns within minutes.
The most intense rainfall was recorded in Mungia, where 11.7 liters per square meter fell in just 10 minutes. In Galdakao, the figure reached 10 liters, in Bermeo — 8.8, in Abusu — 8, in Sangroniz — 7.1, in Matxitxako — 6.1, and in Orozko — 5.4 liters. Such volumes of water in such a short time caused serious problems on the streets.
Flooding in Bilbao
In Bilbao's historic center, the intensity of the rainfall overwhelmed the sewage systems. On Calzadas de Mallona, water flowed down from the Begoña hill, turning the street into a rushing stream that reached Unamuno Square. Local services were forced to respond urgently to numerous calls from residents facing flooded entryways and roads.
Further rainfall expected
The yellow weather alert level in the region will remain in effect until 9:00 p.m. on Friday. Authorities warn of the likelihood of more heavy rains and urge residents to exercise caution, especially in areas already affected by flooding. According to RUSSPAIN.COM, such weather events have become increasingly frequent in recent years, prompting municipalities to reconsider stormwater management measures.
Context and consequences
The situation with heavy rains in Biscay is a reminder of how quickly weather conditions can affect urban life and the work of public services. At the same time, as recent experience in European cities has shown, unexpected natural phenomena can change the course of events even in areas such as sports: for example, the Europa League match between Braga and Freiburg also took place in challenging weather, which affected the dynamics of the game.
