Heavy rains in early October caused the Mapocho River to overflow in the city of Talagante, submerging neighborhoods and forcing residents to seek higher ground. Police and emergency crews responded with helicopters that air‑lifted families and pets from flooded homes, marking a dramatic rescue operation in central Chile.
Santiago recorded 74 mm of rainfall in the first seven days of the month, the wettest October in 76 years for the area. Meteorologists link the record‑set precipitation to the unusually strong El Niño phenomenon, which is forecast to continue delivering wet weather, powerful winds and storms throughout the southern hemisphere’s spring.
Officials confirmed one death in a flooded underpass in San Bernardo, south of Santiago, though the exact cause is still under investigation. The incident underscores the heightened risk of flooding during the ongoing El Niño cycle, a climate pattern that is projected to intensify precipitation in Chile.
Climate experts warn that the 2026‑2027 El Niño episode could bring major weather shifts worldwide, provoking droughts in some regions and floods in others. In central Chile, above‑average rainfall is now expected, raising concerns for communities that have already faced repeated flooding events.
