Coastal areas in Southern California, including Malibu, Long Beach, and Ventura, face heightened risks of flooding and beach erosion due to elevated sea levels and storm surges. The combination of Tropical Storm Rachel and the Kelvin wave could lead to isolated damage in vulnerable areas. Strong rip currents and dangerous waves will increase the risk of drowning for beachgoers. Inland areas may experience light to moderate rainfall, with minimal risk of debris flows or landslides. Winds could disrupt outdoor activities and boating, particularly on Sunday, when gusts are expected to peak.
