Storm Kristin was a named Atlantic storm that struck Portugal in late 2024, bringing heavy rainfall, strong winds (gusts exceeding 100 km/h in some areas), and significant coastal wave action. The storm caused widespread flooding, roof collapses, fallen trees, and power outages across several districts.
IPMA issued orange and red warnings for affected regions, and ANEPC activated emergency response plans. The impact was particularly severe in flood-prone areas of the Lisbon metropolitan area and the Tagus and Mondego river basins, where drainage systems were overwhelmed.
Storm Kristin highlighted recurring vulnerabilities in Portugal's infrastructure during extreme weather events — including urban drainage capacity, riverbank management, and the need for updated emergency response coordination. Residents in storm-affected areas were advised to follow civil protection guidance, avoid coastal zones and riverbanks, and report damage through municipal services.
