Badalona floods have reignited a critical debate about Catalonia’s emergency alert protocols.
Intense rainfall on Tuesday caused significant disruption across the Barcelona metropolitan area, with Badalona bearing the brunt of the damage.

However, the Generalitat’s Civil Protection service chose not to activate the ES-Alert mobile warning system, a decision now under scrutiny from residents and local officials.
Why Mobile Alerts Were Withheld During Badalona Floods
According to sources from Civil Protection speaking to El Periódico, the meteorological forecast consistently indicated a low-risk scenario. Consequently, no European weather model predicted the actual intensity of the rainfall that ultimately occurred. The episode involved a highly localised storm, primarily affecting the Badalona area, which produced accumulations beyond what weather services had anticipated.
One key factor in understanding the decision was the type of risk involved. Authorities detected no “hydrological risk” at any point, meaning there was no danger of rivers, streams, or ravines overflowing. The risk was classified as “pluvial flooding,” caused by the drainage system’s temporary inability to handle large volumes of water in a short time. This type of event, while causing material damage and inconvenience, is considered less immediately life-threatening.
The ES-Alert system, Civil Protection defends, is designed for exceptional situations where a serious and immediate risk to life exists. Furthermore, its activation requires a high degree of certainty about the danger and its potential impact on the population. Municipalities were nevertheless informed, with alerts sent to town halls at 3pm, 4pm, and 5pm about an incoming storm front that could be intense.
A significant increase in calls to the 112 emergency number from Badalona began around 6:30pm. Civil Protection then contacted emergency services, who confirmed water accumulation on public roads. However, by that time, the storms were already subsiding. Therefore, with the information available and no clear signs of imminent danger to life, authorities maintain the conditions for a mass mobile alert were not met.
This incident highlights the growing challenge of predicting and communicating increasingly intense and localised weather phenomena. The debate now centres on how to effectively warn the public about events that, while not meeting the strict criteria for a hydrological emergency, can still cause widespread disruption and significant property damage. This discussion is particularly relevant as other parts of the region face their own infrastructure challenges, such as the recent disruptions on the L5 metro line.
