The primary risk for the Bay Area is coastal flooding, which could be exacerbated by the combination of El Niño, King Tides, and storm surges. Sea levels along the California coast may rise by up to 12 inches (30 cm) due to ocean warming, with King Tides adding another 12 inches (30 cm). Winter storms could push water levels several feet higher, creating a scenario where water levels are 3 to 4 feet above normal. This poses a significant threat to shoreline properties, infrastructure, and low-lying areas. Flash floods, mudslides, and debris flows are also possible during heavy rainfall events.
