The active storm and swell patterns in the Pacific pose risks to coastal areas in Hawaii and California. East-facing shores in Hawaii will experience dangerous surf and rip currents as Hurricane Fausto's swells build, potentially reaching warning levels by July 28. Southern California will see long-period swells from Tropical Storm Genevieve starting July 29, with wave heights potentially exceeding 5 feet. Mariners and coastal residents should prepare for hazardous conditions, including strong currents and elevated surf levels.
