Rio Mobilizes Preventive Plan as El Niño Forecasts Intensify

Overview

• The municipal government announced a package of preventive measures at the Centro de Operações Rio to limit damage from extreme heat and heavy rainfall.
• City leaders highlighted about R$1 billion earmarked for flood-control works and related infrastructure upgrades in vulnerable neighborhoods.
• Operational steps include round-the-clock monitoring with pluviometers and radars, 165 community sirens, and a protocol to open 270 cooling points if needed.
• Mayor Eduardo Cavaliere warned that completed and ongoing works reduce risk but leave many sensitive areas exposed to extreme events during the high-risk season.
• International and local forecasts show an intensifying El Niño expected to peak in the Southern Hemisphere spring–summer, a pattern that raises the chance of hotter temperatures and more intense storms and that may push temperatures higher by late winter.
