The strong El Niño is expected to bring more frequent and intense winter storms, leading to risks such as flooding, mudslides, and coastal erosion. Coastal areas, including state parks, face threats to infrastructure, such as roads, trails, and campgrounds, due to higher sea levels and storm surges. Inland regions, particularly in the Sierra and Central Valley, may experience flooding from heavy rainfall and runoff. Marine ecosystems are also at risk, with warmer waters disrupting food chains and affecting wildlife. Visitors to coastal parks are advised to exercise caution due to unstable bluffs and high surf conditions.
