Residents of Kauai County, including Kauai and Niihau, should prepare for strong winds, heavy rainfall, and potential flash flooding. The steep terrain increases the risk of mudslides, particularly on Kauai and the Big Island. Researchers and staff in the Papahanaumokuakea Marine National Monument should also remain vigilant. Coastal areas may experience dangerous waves and elevated tides, though Hawaii is less prone to storm surge compared to regions like the Gulf of Mexico. Local officials are urging preparedness to mitigate risks.
