The controlled discharge from the Aguieira Dam has raised the Mondego’s level and increased the likelihood of a centennial-level flood in central Coimbra. Several railway links and roads are already affected, with transport disruptions and infrastructure at risk. Local authorities and emergency services are monitoring the river closely, issuing advisories and managing responses; residents and travellers are advised to follow minute-by-minute updates as flood forecasts and dam releases evolve. The situation poses short-term travel, safety and logistical challenges and will require coordinated emergency and transport management if levels continue to rise.

Civil Protection has issued warnings for flood-risk areas, particularly in the Mondego region, following the collapse of part of the A1 motorway pavement near the Mondego River. The incident occurred after a dyke failure, leading to the closure of the motorway in both directions. Authorities are monitoring the situation closely as additional subsidence has been reported due to landslides.

The National Emergency and Civil Protection Authority has issued a warning about potential flooding risks near major rivers due to ongoing heavy rainfall expected to last until Wednesday. In response, the municipalities of Coimbra, Soure, and Montemor-o-Velho have activated evacuation plans affecting over 3,000 residents. Additionally, the political landscape has shifted with the resignation of the Minister of Internal Administration, which has been accepted by the President of the Republic.

Authorities in Alcácer do Sal report a 'brutal' and rapid rise in the Sado river's flow but say the situation remains under control. Civil Protection is monitoring conditions, has evacuation plans ready should riverside areas flood, and expects the flow to rise slightly more before beginning a slower fall from around 04:00—timing that will depend on further rainfall and dam management decisions. Updates will hinge on precipitation forecasts and operational releases from upstream infrastructure.

Following post-depression Kristin, the Government has declared a state of calamity for 60 municipalities as Civil Protection warns of an elevated flood risk in the coming days. The measure centralises resources and fast‑tracks emergency funding, placing urgent demands on local services for evacuation planning, infrastructure inspections and continuous minute-by-minute weather monitoring. Authorities urge residents to follow official updates, prepare for possible evacuations and heed flood warnings as forecasts evolve.

Coimbra authorities will begin preparing measures to prevent a potential evacuation after water releases at the Aguieira dam, the mayor told Lusa. Officials will closely monitor river levels and conditions to assess whether evacuation of people and animals becomes necessary and to coordinate public-safety and emergency-response actions if flood risk increases.
