Severe Sudden Storm Floods Parts of Milan, Firefighters Deploy Over 50 Interventions

A violent flash storm struck Milan and its northern suburbs during the night of June 5‑6, 2026, delivering intense rainfall measured at up to 90 mm per hour in Cinisello Balsamo and 51 mm in one hour in the same area. The downpour caused rapid swelling of the Seveso River, prompting authorities to activate the Bresso flood‑control basin and raise concerns about the Lambro River.

More than 50 emergency calls were handled by the provincial fire brigade, which focused on clearing fallen trees, rescuing flooded streets and addressing other safety hazards. Local officials, including assessor Marco Granelli, confirmed the scale of the event and coordinated civil‑protection efforts to protect residents and infrastructure.
