The flooding has caused damage to homes and infrastructure in Southern California's coastal areas, particularly in low-lying and harbor regions. Beachfront properties are at risk of further erosion due to elevated surf and high tides. Dangerous rip currents pose a threat to swimmers and surfers, while the rain and thunderstorms may lead to additional localized flooding. Residents in affected areas, including Los Angeles, Ventura, and Orange counties, are advised to remain vigilant. The Santa Ana winds, expected to pick up later in the week, could exacerbate conditions, particularly in inland areas.
