Southern California could experience minor to moderate coastal flooding due to swells from Hurricane Genevieve, especially during evening high tides. Beaches in the region may see dangerous rip currents and strong breaking waves. In Hawaii, east-facing shores are under high surf advisories, with hazardous conditions expected through July 29. Swimmers and beachgoers are advised to avoid the water due to strong currents and large waves. Additionally, the Baja California peninsula and parts of southwest Mexico are already experiencing life-threatening surf and rip currents from Genevieve.
