The primary risks from Tropical Storm Fausto include dangerous surf conditions, strong currents, and potential coastal flooding along east-facing shores. Vulnerable low-lying areas, such as roads, boat ramps, and harbors, may experience minor flooding. Increased rainfall could lead to localized flooding, particularly in windward and mauka areas. Utilities and services may face disruptions, and road closures, such as near the Hanalei Bridge, could occur with little notice. Recreational activities near rivers, streams, and beaches are strongly discouraged due to hazardous conditions.
