A deadly storm surge inundated the coastal city of Penco in central Chile overnight, flooding homes and causing significant infrastructure damage.

The powerful sea conditions have prompted urgent warnings from authorities for residents to avoid the shoreline as the region grapples with the aftermath.

The surge, described as exceptional, saw massive waves crash over coastal defences, rapidly submerging low-lying areas and disrupting daily life for thousands.

Water levels rose quickly in many areas, turning streets into rivers and trapping residents in their homes. Rescue efforts are reportedly underway, though details on specific casualties or the full scale of impact remain unclear.

Chilean officials have begun assessing the full extent of the damage across Penco. Emergency services are mobilising resources, with a primary focus on ensuring public safety and clearing debris.

Chile, a country accustomed to seismic activity and tsunamis, faces regular challenges from Pacific weather phenomena. Coastal cities are particularly vulnerable to such extreme weather events.

As the immediate threat subsides, the focus will shift to long-term recovery and support for affected communities. Authorities continue to stress the importance of caution near the sea until conditions fully stabilise.
