Flooding is expected to impact vulnerable coastal areas, including homes, businesses, and infrastructure. In Southern California, significant flooding could close roads and erode shorelines, while minor to moderate flooding is forecast for Los Angeles-area beaches and harbors. Northern California faces similar risks, with up to 0.58 m (1.9 feet) of inundation above ground in low-lying areas. Humboldt Bay may experience localized flooding near tidal waterways. Residents in affected areas should prepare for disruptions and potential damage to property.
