The lamination basin of the Seveso river, which has been in operation since 6.30 am, has filled up on the outskirts of Milan due to torrential rain that has caused the city's other river, the Lambro, to break its banks and flood parts of the northern city, local officials said.

The Civil Protection's municipal operations centre has been active since Tuesday to monitor the level of the river and coordinate interventions in the city, where Civil Protection and MM teams are at work, also with water pumps, to guard the basin and subways.

In the meantime, the rain continues and the Lombardy Region's Natural Hazards Monitoring Functional Centre has confirmed the orange (moderate) criticality warning for hydrogeological and hydraulic risk for today as well.
