Hurricane Genevieve poses risks of coastal flooding and dangerous surf conditions along the Southern California coast, with swells potentially reaching 5 to 7 feet and breaking waves of 9 to 11 feet by July 30. Lunar high tides and El Niño conditions may exacerbate tidal overflow. In Hawaii, Hurricane Fausto is expected to generate surf of 10 to 14 feet along east-facing beaches, creating hazardous swimming conditions due to strong currents and large breaking waves. Swells from Genevieve are also impacting the southwest coast of Mexico and Baja California, causing life-threatening surf and rip currents.
