The primary risks associated with Hurricane Fausto include flooding from heavy rainfall, strong winds, and high surf with dangerous rip currents. While the storm is expected to weaken to a tropical storm before reaching Hawaii, its exact path remains uncertain, and a southern shift could increase the severity of impacts. East-facing shores may experience swells reaching advisory levels of around 10 feet, posing risks to swimmers and coastal residents. Residents in flood-prone and coastal areas are particularly vulnerable and should prepare for possible evacuations.
