A strengthening El Niño is projected to deliver record-breaking precipitation and coastal flooding across California and global regions.

Climate models indicate that a strengthening El Niño is poised to deliver unusually wet weather and coastal flooding across California and other global regions. The European Center for Medium-Range Weather Forecasts predicts a greater than 90% chance of above-normal precipitation for the California coast from December through February, with some areas potentially receiving 40% to 70% more rain than normal. Climate scientist Daniel Swain noted that the current event is expected to intensify into a "Super El Niño," potentially becoming the strongest on record. This intensification is expected to drive higher sea levels, leading to significant coastal flooding and beach erosion. While the impacts will be most pronounced in the fall and winter months, the World Food Programme warned that the system could push 50 million people into acute hunger by the end of next year. Experts suggest that the advanced notice provided by these models allows governments and communities to prepare for extreme heat, heavy rainfall, and potential disruptions to global food supplies.
