The primary risks associated with Fausto include high surf and dangerous rip currents along east-facing shores of the Hawaiian Islands. A high surf advisory is in effect for the south shores of all islands, with waves of 7 to 10 feet (2.1 to 3 meters), and for the east shores of Oahu and the Big Island, with waves of 10 to 14 feet (3 to 4.3 meters). While most islands are not within the cone of uncertainty, Kauai remains at slight risk of impacts if the storm shifts southward. Residents are advised to monitor updates as any deviation in the storm's path could bring stronger winds and heavier rainfall to the islands.
