The super El Niño is expected to bring widespread coastal flooding, heavy rains, and mountain snow to California, with potential for severe damage to infrastructure and property. The combination of El Niño-driven storms and higher-than-average tides could lead to erosion of fragile coastlines and disruption of transportation routes. According to experts, the rise in coastal water levels could threaten an additional 170,000 people and $60 billion in property. Hazards such as mudslides and landslides are also likely, posing risks to public safety and critical infrastructure.
