Isolated Coastal Flooding Expected Across Hawaiian Islands Through Thursday
The National Weather Service has issued a Coastal Flood Statement that will remain in effect through Thursday afternoon. This alert covers several Hawaiian islands—including Kahoʻolawe, Kauaʻi, Lānaʻi, Maui, Molokaʻi, Niʻihau, Oʻahu, and Hawaiʻi Island—where isolated, minor coastal flooding is anticipated. Residents along low-lying shorelines may notice beach areas that are normally dry becoming temporarily submerged, along with minor erosion and saltwater reaching inland.
Local drivers are advised to steer clear of flooded roadways. However, if driving through saltwater cannot be avoided, the NWS recommends rinsing vehicles thoroughly afterward to prevent long-term damage. Beyond that, it's wise to move electronics, vehicles, and other valuables to higher ground to protect them from water exposure. Boaters and coastal residents should also ensure mooring lines remain secure and watch for seawater overwash near boat ramps and beaches. Securing canoes or watercraft on the shore is also part of the preparedness checklist.
If you happen to capture coastal flooding images, consider submitting them to the University of Hawaiʻi Sea Grant College Program’s King Tides Project via PacificIslandsKingTides.org—your submissions could support coastal research and awareness efforts.
